How can we tell from an HP WiFi card spec whether the NIC is 2.4GHz or 5GHz,
or both?

I'm trying to help my sister buy an HP laptop on the web.

My problem is that I contacted HP Support (via their chat mechanism) because USA
phone support is not open now, and technical support isn't open tomorrow.

All I want to know is HOW to tell if a WiFi card has both 2.4GHz and 5GHz.

For $300 at Costco, plus $30 for shipping, this seems to be a decent 15.6-inch
display laptop:
http://www.costco.com/HP-15z-Laptop-|-AMD-E1-|-Windows-10.product.100222779.html

The main drawback from that Costco offering is that the WiFi isn't "ac", there's
no mention of bluetooth, and the laptop doesn't come with Office 2013.

But, we can fix that at the HP web site.

If we go to the HP site to buy it, we can customize it to add what Costco doesn't
have (and get free shipping).
http://store.hp.com/us/en/pdp/Laptop...&TabName=specs

0. We start with the HP price of $350 which comes with twice as much memory as
Costco's (4GB - 8GB) plus free shipping (worth $30), so it's only $20 more
than the Costco price.
1. We add the Microsoft Office Home & Student 2013 from HP for an extra $140 (either
boxed, or already installed - I suggest they get the box for easier re-use later).
https://store.hp.com/webapp/wcs/stor...tNumber=QM4342
2. We add a WiFi "ac" card from HP for an extra $30 but is it dual band, 2.4GHz and
5GHz or not?
3. We add an extra wireless mouse and keyboard (no wires!) for $30 (because my sis
wants that).
https://store.hp.com/webapp/wcs/stor...=LV290AA%23ABA
The resulting price is $550 + tax (free shipping).

For that price, I see she gets a good laptop, but I chatted for half an hour with the HP
sales chat people and they couldn't confirm if this 802.11 n/ac laptop has both
2.4GHz and 5GHz or if it only has one of those two frequencies.

HP chat sent me this URL but it just confirms that both "ac" and "n" don't have to be dual
band; either one can be a single band. Also, it confirmed the 1x1 or 2x2 or 4x4 just means
the number of dedicated data transmit and data receive antennas, which says absolutely
nothing about the frequency.

Looks at the specs. If it says 802.11 followed by:
b/g = 2.4 GHz only
b/g/n = 2.4 GHz only
a = 5 GHz only
a/b/g/n = 2.4 and 5 GHz
The key is the "a" as in 802.11a, which is 5 GHz only.

Buy a few spares as I've been shipped defective receivers.

Office 2013 is usually extra. If you must have Microsoft Office, look
at Office 365 or the various Office Mutations available. Or, use free
open source software such as Libre Office or Open Office. There are
also Office alternatives:

When I bought my HP I got the starter version of Excel and

Keep in mind some WiFi card in HP laptops are white listed. You can't
install(or upgrade) with any WiFi card. BIOS won't allow it. I use
OpenOffice and it is free. Don't have to use word or excel.

I am lost on the questions and answers that you guys are posting.
I never hear of different WiFi to me all are universal speed depend

Hi,
-AC mode runs on 5GHz band, -N can run on either.
So, it'll be dual band card, 2 stream one(2 antennas)
Full -AC needs 4 antennas and there are almost no such thing
yet for users. Of course it'll have Gbit Ethernet controller too.
Does it have Bluetooth? Bluetooth mouse and keyboard?
8 GB memory is good. You don't have to spend 140.00 on MS Office.
Freeware Openoffice is compatible with MS Office. Let her try it and
you can buy MS later on student discount. And what cpu, and Video
controller?(what is native resolution?) I am sure the laptop will have
HDMI port and sufficient no. of USB port. And my(very robust game
machine with enough cpu and video controller power) daily use laptop is
14", i7 quad cpu, 8GB memory Nvidia 740M video card and DVD r/w drive,
etc. gotten for ~500.00 on eBay. Built-like tank. Never let me down. I
never owned HP laptop. Personally I just don't like it. But I used many
different Enterprise grade HP work stations or server.
Most people use Intel 7260 dual band WiFi card. I have it in all our
laptop except my wife's Asus GX60 which has Bigfoot Killer N card.
I seldom use desktop any more. At home I use 17" Asus ROG with SSDs,
16GB memory, Nvidia 840m video card, i7 quad cpu, Blue ray R/W drive,
etc. I use this for my real work. triple boot, W7 x64, Ultimate, W10 Pro
and Ubuntu. (What real work? I am retired old fart, LOL!)

Office 365 is stupid, for anyone buying only 1 copy of Home & Student,

Basically, the WiFi cards for the Costco & HP web pages, do NOT list
the frequency. I won't recommend a laptop that does not have *both*
2.4GHz and 5GHz.

I just want to know how I can be sure of that, when they don't bother
to list the frequencies in the WiFi specs!

Here is the HP spec for that laptop:

No. Both 802.11a and 802.11ac are 5 GHz only. Just look for the "a"
and it should be able to do 5 GHz in some manner.

Are you sure? Office 365 can be installed on 5 machines. If the
skool has 5 machines of any type, which makes the price for each
machine about $20/year.
http://www.microsoftstore.com/store/msusa/en_US/pdp/Office-365-Home/productID.286395000
Meanwhile, Home and Student is $140 and should last about 5 to 7 years
before it become too old to use. At an optimistic 7 years, that's the
same $20/year per machine as Office 365.

Back to the "a", which is 5GHz and "g" which is 2.4GHz.
What if it's 802.11 b/g/n/ac ?

No such thing. In order to do "ac", it will need to also do "a". So
the typical designation will be:
802.11 a/b/g/n/ac

I know who Jeff is. -a is another mode consumers do not bother.
I can buy a legit key for MS Office 2015 for 30.00 or so.
Download it and use that key to activate. Always worked for me.
I even bought keys for my surveillance camera use on Synology NAS.
Real =AC mode, 80MHz wide is full -AC with 4 MIMO(4 antennas) and some
will work on MU-MIMO(yet to come by Qualcom, Quantenna, etc.)
You just specify dual band card as an option. Some HP laptops don't
like any card. HP has white list of WiFi card.

I would guess the number 3 will certainly do 5 GHz. However, the web
designers truncated the letters that designate the all the protocols,
listing only the highest (fastest) 802.11ac. Presumably, that would
include all the lesser protocols, including 802.11 a/b/g/n. However,
I can't be certain without knowing the Intel model number of the
wireless card.

Who cares about -b ancient slowest mode. G, N, AC. If it is AC card or
router AC is downward compatible with slower modes.Student version lacks
some features and miscellaneous things. Why do you think it is cheaper?
WiFi is 2 way street one laptop has AC card does not mean it'll be
faster, corresponding device at the other end should be AC
capable too. If AC card talks to N card speed will be that of N.

I am lost on the questions and answers that you guys are posting.

Basically, the WiFi cards for the Costco & HP web pages, do NOT list
the frequency. I won't recommend a laptop that does not have *both*
2.4GHz and 5GHz.

I just want to know how I can be sure of that, when they don't bother
to list the frequencies in the WiFi specs!

Here is the HP spec for that laptop:
http://store.hp.com/us/en/pdp/Laptop...ptop-m7d88av-1

I can't tell which WiFi card has *both* 2.4GHz and 5GHz.

The option Intel -AC card with Bluetooth is what you want then.
This one is dual band(2.4GHz, 5GHz) This is AMD cpu based laptop.
A10 is the top end one. Video card... Rxxxx. xxxx at higher number is
better one. Any more questions? Don't forget to read reviews on this
model to see whether buyers are happy or not.

Look at this screenshot:

If I press the customize button, I have three WiFi card choices.

1. 802.11b/g/n WLAN [1x1]
2. 802.11b/g/n WLAN and Bluetooth(R) [1x1]
3. Intel 802.11ac WLAN and Bluetooth(R) [1x1]

Which of those is *both* 2.4GHz and 5GHz?
How do I know?

Again No. 3 Looks like basic dual band being 1x1, not 2x2 or 3x3.

FWIW, this Lenovo ThinkPad W550s has two cards listed as options:

-- Intel 7265 AC/B/G/N Dual Band Wireless + Bluetooth Version 4.0"

Number 3 is: "Intel 802.11ac WLAN and Bluetooth [1x1]".
So, what does that tell us?

Are we saying the "ac" is both 2.4GHz & 5GHz by virtue of the "a" in "ac"?

No such thing. In order to do "ac", it will need to also do "a".
So the typical designation will be: 802.11 a/b/g/n/ac

Unfortunately, the "typical" designation doesn't help us here.
The HP spec, as you have seen, just says "ac" for the high end card.

She's a teacher. Not a school.

She only has an ancient WinXP desktop that has Office 2007 on it.
When she gets a new laptop, she needs a new Office anyway.

1. Renting Office 365 for a laptop costs $100/year and can be put on 4
more non WinXP machines that don't actually exist. After 7 years, renting
cost her $700 for Office for that one laptop, which is more than the
laptop costs.

2. Buying Office 2013 costs her $140, and can be put on one desktop and
one laptop. Since the desktop is WinXP, the additional license is moot,
so, it costs her $140 for 7 years (or 10% less with the teacher discount).

It's a no brainer, to me; but this isn't the question in the OP, so it's
just an offshoot discussion which isn't at all confusing to me.

Office 365 is stupid, for anyone buying only 1 copy of Home & Student,

ten times over with the subscription than with the one price.

No. But if you google "Intel 802.11 ac wifi Bluetooth" you'll see
it says the Intel product supports dual band. All the similar products
I've seen do too and I'd say you're 99% certain the product you're buying
does too. Notebooks have to work everywhere and it would be pretty
dumb to have some unusual card that doesn't support the older standards.

In fairness, his issue is that while I think all the AC cards I've
seen say "dual band", and I think it's 99% sure that this one does
too, the HP website doesn't specifically say it. And he said that he
did ask HP and couldn't get an answer from them, which is amazing.
The best source here is that HP says it's an Intel product and googling
what Intel has, I only see one card and it's dual band. That and the
fact that it would be very dumb to sell a notebook that can't connect
to older networks, is enough for me.

No, because they are obviously the same Intel card, the same part #
and Intel isn't dumb enough to have a wifi AC card that can't also
connect to older networks. That card is dual band, period.

Grab Belarc Advisor, run it on the XP machine, and PRINT the results.
Somewhere in there, it will have the various serial numbers needed for
the installation. If the ancient XP machine crashes without a backup
or a list of serial numbers, she will not be able to reinstall Office

Right. With only one machine, Office 365 doesn't make economic sense.
I was thinking of a skool, not an individual user. I still think the
various alternatives (Google Office, LibreOffice, etc) are worth
investigating.

Good luck.

It tells me that HP marketing is clueless. The assumption is that
anything that does "ac" will also do the lesser protocol of "a". Since
"ac" only works on 5GHz, and nobody today makes a 5GHz only radio,
it's a fair assumption that anything with "ac" will be dual band.
However, that's an assumption. I tried to find the Intel card used in
the 15z and failed. You'll probably have to ask HP pre-sales, this I
predict will be clueless. You might try the HP support forums.

Yes, but the "a" and "ac" are a concidence. The IEEE 802.11
committee(s) ran out of letters when they hit "z", so the started
using two letter suffixes as in "as", "ab", "ac", etc. There fact
that "a" and "ac" are both "5GHz only" is purely coincidental and
should not be relied upon to determine if something operates on 5GHz.

As I mentioned before, if it does "ac", it should be able to do "a".
Nobody makes a 5GHz only radio these days, so if it does 5GHz in any
form, it should also be able to do 2.4GHz. However, these are logical
deduction and assumptions which should not be relied upon. To be
sure, you need to pry the Intel product number out of HP and lookup
the specs on the Intel web site, which should have a better
description of the products capabilities.

OK. I'll wait while you review the session so that I won't need to repeat
anything.
Basically, I can't believe it's this difficult to just ascertain whether
the laptop has a WiFi card that handles both the 2.4GHz and the 5GHz
bands.
Also, since"
&nbsp that simple question wasn't answered, it's hard to know if the
answer I got regarding the shipping being free but that there was tax, is
correct, or not.
Neither of these questions is difficult for someone who handles basic
(and these are EXTREMELY BASIC
&nbsp questions) computer questions.
09/06/2015 08:41:03PM Agent (Vann): "Yes, I see that you have
questions, Ewald."
09/06/2015 08:41:05PM Ewald Bohm: "If the spec sheet simply gave the
information that it should give, I wouldn't even NEED to ask these
questions."
09/06/2015 08:41:47PM Ewald Bohm: "I know the broken record; and I know
that you're taught to "reflect" the customer's question - but let's just
get the answer please (I was a customer support manager for two decades)."
09/06/2015 08:41:54PM Agent (Vann): "Yes, I understand that our website
product information is very limited."
09/06/2015 08:43:31PM Agent (Vann): "The shipping charge is zero and
that is for free."
09/06/2015 08:44:03PM Agent (Vann): "Sales tax will apply to the
product price itself and its computation is based on the shipping zip
code and state."
09/06/2015 08:45:12PM Ewald Bohm: "Hi Vann,
Thank you for confirming that the sales tax is based on where the item
will be shipped and that the shipping is free.
Now all we need to know is whether the three WiFi card options available
for this laptop are 2.4GHz or 5GHz or both."
09/06/2015 08:45:30PM Agent (Vann): "Yes, I am actually checking on
that."
09/06/2015 08:46:04PM Agent (Vann): "Honestly, our tools and resources
are very limited to answer your question."
09/06/2015 08:46:16PM Agent (Vann): "I totally understand why the agent
referred you to our product expert."
09/06/2015 08:46:25PM Agent (Vann): "However, let own this question and
I will this to you."
09/06/2015 08:46:28PM Agent (Vann): "*answer."
09/06/2015 08:46:35PM Agent (Vann): "Now, can you give me 1-2 minutes
of your time."
09/06/2015 08:46:41PM Agent (Vann): "I am checking on something here."
09/06/2015 08:47:43PM Agent (Vann): "Ewald,"
09/06/2015 08:47:46PM Agent (Vann): "I am sorry for that."
09/06/2015 08:48:10PM Ewald Bohm: "I am here - and will wait."
09/06/2015 08:49:00PM Agent (Vann): "Ewald, I can tell this by the
decription of the WLAN card. Everytime you see a wlan card listed as b/g/
n, it is a single band (2.4 GHz) card."
09/06/2015 08:49:58PM Ewald Bohm: "HI Vann"
09/06/2015 08:50:03PM Agent (Vann): "I found more information here."
09/06/2015 08:52:01PM Ewald Bohm: "oooPS.
Hi VAnn,
I believe you can have 5GHz on "n"but not on "g" but I can check that
out. Certainly "ac" would benefit from 5GHz, but are you saying that only
the "ac" card is 5GHz?"
09/06/2015 08:52:54PM Agent (Vann): "I am verifying that."
09/06/2015 08:53:17PM Agent (Vann): "I cannot confirm it yet and this
is based on something that I am not sure of."
09/06/2015 08:54:33PM Ewald Bohm: "Hi Vann
Look at this web site (http://pocketnow.com/2014/01/23/5ghz-wifi).
Notice that "b" and "g" are ONLY 2.4GHz - but - notice that either "n" or
"ac" is also 5GHz."
09/06/2015 08:57:20PM Agent (Vann): "Thanks!"
09/06/2015 08:57:32PM Agent (Vann): "Let me check that."
09/06/2015 08:59:32PM Ewald Bohm: "Hi Vann
So, we still don't have the answer, since clearly both "n" and "ac" can
do 2.4GHz and 5GHz - the only difference is that "n" can do either one at
a time while "ac" does both at the same time - but that's not my question.
My question is whether th"
&nbsp e "n" and "ac" cards from HP for this laptop are 2.4GHz or 5GHz
or both.
Thanks for "owning" this issue to the conclusion - since - it's actually
an easy question - for someone who has the spec to answer.
In fact, I fault HP for not putting that answer on
&nbsp the web site since it's a CRITICAL question to ask!
09/06/2015 09:00:18PM Agent (Vann): "Ewald, I see where you are coming
from."
09/06/2015 09:00:53PM Agent (Vann): "I even sent a quick email to the
marketing department and web content team to put a brief pertinent
description of each wi-fi options."
09/06/2015 09:04:48PM Ewald Bohm: "Hi Vann,
As I had said, I was a customer-support manager for twenty years and I
found only about 10% of the support team would take the time to solve
long-term problems such as missing information in a web page; therefore,
I do appreciate that you are in"
&nbsp the top 10% for "owning" the problem, and I appreciate that.
I'm still not sure though, whether the specific cards available for this
laptop have "both" 2.4GHz and 5GHz bands, since we have ascertained that
"n" can be either (just not at the same time), w
&nbsp hile "ac" also can be either (but if it has both, it can do both
at the same time).
So, the FREQUENCY BAND is a critical piece of data that a person needs to
figure out if their laptop will connect to the "n" or "ac" 2.4GHz or 5GHz
bands.
09/06/2015 09:04:55PM Agent (Vann): "Ewald, as far as what I understood
in my readings here. You need a dual band that can support both 2.5 and 5
Ghz."
09/06/2015 09:05:26PM Agent (Vann): "This is what you need WLAN 802.11
ac 2x2 ."
09/06/2015 09:05:35PM Ewald Bohm: "Hi Vann,
Yes. I will ONLY BUY a dual-band card. I am just trying to figure out
which card(s) that fit that laptop are dual band."
09/06/2015 09:05:50PM Ewald Bohm: "Note: It's 2.4GHz and not 2.5GHz."
09/06/2015 09:06:10PM Agent (Vann): "Sorry for the typo error."
09/06/2015 09:06:18PM Agent (Vann): "So you are saying that your router
has a dual band?"
09/06/2015 09:08:41PM Ewald Bohm: "HI Vann,
I know MANY (most) "ac" cards will be dual band. But, remember, an "ac"
card can also be one or the other. So, I am just trying to CONFIRM
whether the "n" and "ac" cards you offer actually make use of both bands.
(I know that the "n" can make use"
&nbsp of either band, and so can the "ac", with the only difference not
mattering to this question that "ac" can do it simultaneously).
But, "ac" can't do it simultaneously if it doesn't have both bands, and
"n" cards can be of three types (1) only 2.4, (2) o
&nbsp nly 5Ghz, or (3) both 2.4GHz and 5GHz.
As for my router, it is dual band (both 2.4GHz and 5Ghz) and it is an
AC1750.
09/06/2015 09:14:10PM Ewald Bohm: "Hi Vann
The 802.11n spec allows up to 4 transmit and four receive antennas
(802.11n supports up to 4x4), so, again, just knowing it's 2x2 or 4x4
does not tell me what the bands are."
09/06/2015 09:17:33PM Agent (Vann): "Ewald, I am sorry if I kept you
waiting."
09/06/2015 09:17:40PM Ewald Bohm: "I'm here ..."
09/06/2015 09:18:06PM Agent (Vann): "This is overly complicated and it
would be better you consult our product expert."
09/06/2015 09:18:23PM Agent (Vann): "As far as I know that if it has a
1x1 that is a single band which can support up to 2.4ghz/"
09/06/2015 09:19:36PM Ewald Bohm: "The 1x1 means one (dedicated)
transmit antenna and 1 (dedicated) receive antenna; the antenna itself
can be any frequency (either 2.4GHz or 5GHz) but almost all the time, it
is 2.4GHz (I agree) but it does not have to be since the 1x1 is
indicating the de"
&nbsp dicated "channels" and NOT the frequency band!
09/06/2015 09:20:46PM Agent (Vann): "It looks you've done more research
on this and you get a lot of understanding how these things work."
09/06/2015 09:21:36PM Agent (Vann): "Can you check this link http://
http://www.intel.com/content/dam/www...t-gen-80211ac-
wifi-for-dummies.pdf"
09/06/2015 09:21:58PM Ewald Bohm: "I know that the 2x2 has two
dedicated "channels" (i.e., antennae), 2 for transmit and 2 for receive.
But, again, that does not indicate the FREQUENCY. It "could" mean that
they are using 2 frequencies - but - it could also mean that they're NOT
using 2 d"
&nbsp ifferent frequencies.
09/06/2015 09:22:07PM Ewald Bohm: "checking the link ..."
09/06/2015 09:22:53PM Ewald Bohm: "Looking for the specific page ..."
09/06/2015 09:24:08PM Agent (Vann): "I also read from the HP Forums."
09/06/2015 09:24:09PM Agent (Vann): "http://h30434.www3.hp.com/t5/
Wireless-Internet-Home-Networking/WiFi-Connections-HP-laptop-unable-to-
find-5Ghz-wireless/td-p/3300523"
09/06/2015 09:24:31PM Agent (Vann): "A dual band card would be listed
as either a/b/g/n or a/g/n."
09/06/2015 09:25:00PM Ewald Bohm: "VAnn, you'll notice that, on page 10
of the wifi for dummies, it confirms what I said, which is (verbatim):
"In the vernacular of the new multispeed Wi-Fi stan
-
dards, the number of send and receive antennas and
stream configurations are noted as 1x1 (o"
&nbsp ne antenna
supporting one data stream), 2x2 (two antennas sup
-
porting two data streams), and 3x3. Table 2-2 compares
the performance of antenna and stream configurations
in the 802.11n and 802.11ac standards"
09/06/2015 09:25:31PM Ewald Bohm: "So, the 2x2 just means the number of
antennas. It tells us NOTHING about the frequency."
09/06/2015 09:26:15PM Agent (Vann): "Ewald, I will have to refer this
to our product expert and I shall email you the answer."
09/06/2015 09:26:38PM Agent (Vann): "This would consume so much of our
time and this is something that I cannot confirm."
09/06/2015 09:26:44PM Ewald Bohm: "Hi VAnn,
An "n" card can be dual band - but an "n" card can also be single band.
That is why the SPECIFICATION is so important. We'd never have to ASK the
question if the spec simply said what it should say!"
09/06/2015 09:26:48PM Agent (Vann): "I admired how you are really want
to get the answer of this."
09/06/2015 09:28:23PM Agent (Vann): "I will email the product expert
with your questions."
09/06/2015 09:28:24PM Ewald Bohm: "HI Vann,
If the specifications were written correctly, we'd never have to ask. In
the book you kindly referenced, you'll see this exact quote on the first
line of page 11:
"Wi-Fi works over two spectrum bands: 2.4 GHz and
5 GHz. Older 802.11bgn uses the"
&nbsp 2.4 GHz frequency"
09/06/2015 09:28:35PM Agent (Vann): "Can you summarize your questions
now so I can forward this now."
09/06/2015 09:28:54PM Agent (Vann): "I will be able to email you within
24-248hrs once I get a reply from the product expert."
09/06/2015 09:29:09PM Ewald Bohm: "Later, in that same page, it says
what I'm trying to tell you, which is that "n" can be either 5GHz or
2.4GHz or both."
09/06/2015 09:29:14PM Agent (Vann): "This is already beyond on my basic
technical knowledge, Ewald."
09/06/2015 09:29:23PM Ewald Bohm: "OK ... gimme a sec... to simplify..."
09/06/2015 09:30:12PM Agent (Vann): "Sure."
09/06/2015 09:32:36PM Agent (Vann): "Please do as this already rambling
in my head."
09/06/2015 09:33:10PM Ewald Bohm: "I would like to know if the three
available WiFi cards for the HP 15z laptop (http://store.hp.com/us/en/pdp/
Laptops/hp-pavilion-15z-laptop-m7d88av-1#!&TabName=specs) are 2.4GHz,
5GHz, or both.
I realize that the "n" 802.11 spec can be either only 2.4GHz o"
&nbsp r 5GHz or both (just not at the same time); and I am aware that
the 802.11 "ac" spec also allows for either only 2.4GHz or 5GHz or both
(possibly at the same time); so the fact that it's "ac" or "n" tells me
NOTHING about the frequency band!
In addition,
&nbsp I realize that 1x1 means one dedicated transmit antenna per
channel and 1 dedicated receive antenna per channel, just as 2x2 means 2
dedicated transmit antennas per data channel and 2 dedicated receive
antennas per data channel, which again, tells me NOTH
&nbsp ING about the frequency band!
09/06/2015 09:34:06PM Agent (Vann): "I will take note of this and what
you exactly write here will be forwarded to the product expert."
09/06/2015 09:34:31PM Agent (Vann): "I am very sorry if I failed to
answer by myself."
09/06/2015 09:34:57PM Agent (Vann): "This is already beyong my power
and knowledge. I really to get an answer for you immediately but this mix
up in my head."
09/06/2015 09:35:06PM Agent (Vann): "I am sorry for the typo error."
09/06/2015 09:36:01PM Ewald Bohm: "OK. Thank you Vann,
I was hoping to purchase the laptop, on the web, tonight, but I will
await the response from your technical expert.
I don't consider this a difficult question because EVERYONE would want to
know what frequency the WiFi card operates in"
&nbsp - and - you can't tell from the fact that it's "n" or "ac" or 1x1
or 2x2, etc.
I have never seen any WiFi card advertised that didn't tell the user the
FREQUENCY (so I am happy that you forwarded information to the web-
marketing team to let them know the
&nbsp ir web pages are missing critical information).
09/06/2015 09:36:55PM Agent (Vann): "Ewald, this is not a common

09/06/2015 08:33:31PM Agent (Vann): "Hi!"
09/06/2015 08:35:14PM Ewald Bohm: "Hi Vann
Thank you for trying to help me.
I am asking a simple question.
Do you need me to repeat the question?"
09/06/2015 08:36:41PM Ewald Bohm: "Is anyone there?"
09/06/2015 08:36:47PM Agent (Vann): "Yes, I am here."
09/06/2015 08:36:53PM Agent (Vann): "Sorry for the long wait."
09/06/2015 08:37:02PM Agent (Vann): "I was reading your chat session
with Paige."
09/06/2015 08:40:18PM Ewald Bohm: "HI Vann,
OK. I'll wait while you review the session so that I won't need to repeat
anything.
Basically, I can't believe it's this difficult to just ascertain whether
the laptop has a WiFi card that handles both the 2.4GHz and the 5GHz
bands.
Also, since"
&nbsp that simple question wasn't answered, it's hard to know if the
answer I got regarding the shipping being free but that there was tax, is
correct, or not.
Neither of these questions is difficult for someone who handles basic
(and these are EXTREMELY BASIC
&nbsp questions) computer questions.
09/06/2015 08:41:03PM Agent (Vann): "Yes, I see that you have
questions, Ewald."
09/06/2015 08:41:05PM Ewald Bohm: "If the spec sheet simply gave the
information that it should give, I wouldn't even NEED to ask these
questions."
09/06/2015 08:41:47PM Ewald Bohm: "I know the broken record; and I know
that you're taught to "reflect" the customer's question - but let's just
get the answer please (I was a customer support manager for two decades)."
09/06/2015 08:41:54PM Agent (Vann): "Yes, I understand that our website
product information is very limited."
09/06/2015 08:43:31PM Agent (Vann): "The shipping charge is zero and
that is for free."
09/06/2015 08:44:03PM Agent (Vann): "Sales tax will apply to the
product price itself and its computation is based on the shipping zip
code and state."
09/06/2015 08:45:12PM Ewald Bohm: "Hi Vann,
Thank you for confirming that the sales tax is based on where the item
will be shipped and that the shipping is free.
Now all we need to know is whether the three WiFi card options available
for this laptop are 2.4GHz or 5GHz or both."
09/06/2015 08:45:30PM Agent (Vann): "Yes, I am actually checking on
that."
09/06/2015 08:46:04PM Agent (Vann): "Honestly, our tools and resources
are very limited to answer your question."
09/06/2015 08:46:16PM Agent (Vann): "I totally understand why the agent
referred you to our product expert."
09/06/2015 08:46:25PM Agent (Vann): "However, let own this question and
I will this to you."
09/06/2015 08:46:28PM Agent (Vann): "*answer."
09/06/2015 08:46:35PM Agent (Vann): "Now, can you give me 1-2 minutes
of your time."
09/06/2015 08:46:41PM Agent (Vann): "I am checking on something here."
09/06/2015 08:47:43PM Agent (Vann): "Ewald,"
09/06/2015 08:47:46PM Agent (Vann): "I am sorry for that."
09/06/2015 08:48:10PM Ewald Bohm: "I am here - and will wait."
09/06/2015 08:49:00PM Agent (Vann): "Ewald, I can tell this by the
decription of the WLAN card. Everytime you see a wlan card listed as b/g/
n, it is a single band (2.4 GHz) card."
09/06/2015 08:49:58PM Ewald Bohm: "HI Vann"
09/06/2015 08:50:03PM Agent (Vann): "I found more information here."
09/06/2015 08:52:01PM Ewald Bohm: "oooPS.
Hi VAnn,
I believe you can have 5GHz on "n"but not on "g" but I can check that
out. Certainly "ac" would benefit from 5GHz, but are you saying that only
the "ac" card is 5GHz?"
09/06/2015 08:52:54PM Agent (Vann): "I am verifying that."
09/06/2015 08:53:17PM Agent (Vann): "I cannot confirm it yet and this
is based on something that I am not sure of."
09/06/2015 08:54:33PM Ewald Bohm: "Hi Vann
Look at this web site (http://pocketnow.com/2014/01/23/5ghz-wifi).
Notice that "b" and "g" are ONLY 2.4GHz - but - notice that either "n" or
"ac" is also 5GHz."
09/06/2015 08:57:20PM Agent (Vann): "Thanks!"
09/06/2015 08:57:32PM Agent (Vann): "Let me check that."
09/06/2015 08:59:32PM Ewald Bohm: "Hi Vann
So, we still don't have the answer, since clearly both "n" and "ac" can
do 2.4GHz and 5GHz - the only difference is that "n" can do either one at
a time while "ac" does both at the same time - but that's not my question.
My question is whether th"
&nbsp e "n" and "ac" cards from HP for this laptop are 2.4GHz or 5GHz
or both.
Thanks for "owning" this issue to the conclusion - since - it's actually
an easy question - for someone who has the spec to answer.
In fact, I fault HP for not putting that answer on
&nbsp the web site since it's a CRITICAL question to ask!
09/06/2015 09:00:18PM Agent (Vann): "Ewald, I see where you are coming
from."
09/06/2015 09:00:53PM Agent (Vann): "I even sent a quick email to the
marketing department and web content team to put a brief pertinent
description of each wi-fi options."
09/06/2015 09:04:48PM Ewald Bohm: "Hi Vann,
As I had said, I was a customer-support manager for twenty years and I
found only about 10% of the support team would take the time to solve
long-term problems such as missing information in a web page; therefore,
I do appreciate that you are in"
&nbsp the top 10% for "owning" the problem, and I appreciate that.
I'm still not sure though, whether the specific cards available for this
laptop have "both" 2.4GHz and 5GHz bands, since we have ascertained that
"n" can be either (just not at the same time), w
&nbsp hile "ac" also can be either (but if it has both, it can do both
at the same time).
So, the FREQUENCY BAND is a critical piece of data that a person needs to
figure out if their laptop will connect to the "n" or "ac" 2.4GHz or 5GHz
bands.
09/06/2015 09:04:55PM Agent (Vann): "Ewald, as far as what I understood
in my readings here. You need a dual band that can support both 2.5 and 5
Ghz."
09/06/2015 09:05:26PM Agent (Vann): "This is what you need WLAN 802.11
ac 2x2 ."
09/06/2015 09:05:35PM Ewald Bohm: "Hi Vann,
Yes. I will ONLY BUY a dual-band card. I am just trying to figure out
which card(s) that fit that laptop are dual band."
09/06/2015 09:05:50PM Ewald Bohm: "Note: It's 2.4GHz and not 2.5GHz."
09/06/2015 09:06:10PM Agent (Vann): "Sorry for the typo error."
09/06/2015 09:06:18PM Agent (Vann): "So you are saying that your router
has a dual band?"
09/06/2015 09:08:41PM Ewald Bohm: "HI Vann,
I know MANY (most) "ac" cards will be dual band. But, remember, an "ac"
card can also be one or the other. So, I am just trying to CONFIRM
whether the "n" and "ac" cards you offer actually make use of both bands.
(I know that the "n" can make use"
&nbsp of either band, and so can the "ac", with the only difference not
mattering to this question that "ac" can do it simultaneously).
But, "ac" can't do it simultaneously if it doesn't have both bands, and
"n" cards can be of three types (1) only 2.4, (2) o
&nbsp nly 5Ghz, or (3) both 2.4GHz and 5GHz.
As for my router, it is dual band (both 2.4GHz and 5Ghz) and it is an
AC1750.
09/06/2015 09:14:10PM Ewald Bohm: "Hi Vann
The 802.11n spec allows up to 4 transmit and four receive antennas
(802.11n supports up to 4x4), so, again, just knowing it's 2x2 or 4x4
does not tell me what the bands are."
09/06/2015 09:17:33PM Agent (Vann): "Ewald, I am sorry if I kept you
waiting."
09/06/2015 09:17:40PM Ewald Bohm: "I'm here ..."
09/06/2015 09:18:06PM Agent (Vann): "This is overly complicated and it
would be better you consult our product expert."
09/06/2015 09:18:23PM Agent (Vann): "As far as I know that if it has a
1x1 that is a single band which can support up to 2.4ghz/"
09/06/2015 09:19:36PM Ewald Bohm: "The 1x1 means one (dedicated)
transmit antenna and 1 (dedicated) receive antenna; the antenna itself
can be any frequency (either 2.4GHz or 5GHz) but almost all the time, it
is 2.4GHz (I agree) but it does not have to be since the 1x1 is
indicating the de"
&nbsp dicated "channels" and NOT the frequency band!
09/06/2015 09:20:46PM Agent (Vann): "It looks you've done more research
on this and you get a lot of understanding how these things work."
09/06/2015 09:21:36PM Agent (Vann): "Can you check this link http://
http://www.intel.com/content/dam/www...t-gen-80211ac-

09/06/2015 09:21:58PM Ewald Bohm: "I know that the 2x2 has two
dedicated "channels" (i.e., antennae), 2 for transmit and 2 for receive.

09/06/2015 09:25:00PM Ewald Bohm: "VAnn, you'll notice that, on page 10
of the wifi for dummies, it confirms what I said, which is (verbatim):
"In the vernacular of the new multispeed Wi-Fi stan

stream configurations are noted as 1x1 (o"

09/06/2015 09:25:31PM Ewald Bohm: "So, the 2x2 just means the number of
antennas. It tells us NOTHING about the frequency."

to our product expert and I shall email you the answer."

09/06/2015 09:26:44PM Ewald Bohm: "Hi VAnn,
An "n" card can be dual band - but an "n" card can also be single band.

question if the spec simply said what it should say!"

You have to realize what you're saying, & that your suggestion can't work.

If you were suggesting to "me" to use openoffice or staroffice or
libreoffice or framemaker or numbers-pages-keynote or polaris office or
kingston office or wps office or any number of freeware office look-alike
apps, then your suggestion might actually make a lot of sense.

But, you can't take the average extremely non-technical grade-school
teacher, and seriously suggest they use a free office-like equivalent,
when they have enough trouble just getting used to the ribbon changing
from one Microsoft office version to another.

They complain when they have to open an office 2013 doc in office 2007,
and they fail at that, half the time, without help.

They can't even print something as simples as a protected PDF without my
help.

So, if you're suggesting that free office-look-alikes are "equivalent" to
office for such a person, then you fundamentally don't understand people.

It's just not gonna happen.

You missed the point.

I'm trying to *recommend* a laptop for a teacher who is not technical.
I started at Costco, but the Costco laptop wasn't dual band.
I went to the HP site and can't figure out if it's dual band.

If it's dual band, I'll recommend the teacher buys it.
If not, I will choose another laptop.

I don't actually care what laptop she gets.
I'm just trying to help her.

The laptop has to be about the right size & shape.
It has to be within her price range (around $500 out the door).
It has to have MS Office on it.
It has to be Windows.

Everything else, she's leaving up to me.
One thing I'm requiring is dual band 2.4GHz & 5GHz simultaneously
(with backward compatibility).

All I'm trying to find out is if this HP 15z laptop is dual band.
It's amazingly difficult to find this out.

I'm online right now with a supposedly-special HP customer support sales
hotline (888-999-4747), and they STILL don't know the answer.

Thank you Jeff for clarifying this spec:

After a half hour on three separate HP calls, I learned something (I

2. Advanced HP Tech Support 866-221-4553
3. HP Shopping Team 888-999-4747

HP: They first told me the ac card was just ac.
ME: I told them that this was unlikely, so I asked them to doublecheck.

HP: After a long wait, they told me the "ac" card was backwards
compatible, but it was only 5GHz.
ME: I told them that was impossible.

HP: Then, after another long wait, they told me it was NOT dual band, but
that it had both bands.
ME: I told them that this confused me, and I asked them to clarify.

HP: Finally, they came back and said that the "ac" card was backwards
compatible, so that it had two frequencies, but they don't operate at the
same time, so it's not dual band.
ME: I said thank you but I would like to ask you, Jeff, to clarify.

Does that HP answer make sense?
The "ac" card is backwards compatible, so, it has both frequencies, but
it doesn't do both frequencies at the same time?

What does that really mean?

802.11 ac == 5GHz only

Jeff: Notice the question mark in the "n" spec.
Is "n" always just *either* frequency (i.e., one or the other).
Or can "n" be either one or the other or *both* frequencies?

Office 2007 will run on Win 10:
Grab Belarc Advisor

Jeff.
You are correct.
But you were thinking differently than I was.

You were thinking of bringing the (winxp desktop) 2007 license upward to
the new (win10 laptop), and I discounted that out of hand.

This is a hand-me-down desktop that someone else didn't want, so they
gave it to this teacher, many years ago. It came with zero discs!

But that wouldn't stop you or me.

If it were you or me, we'd use Belarc to find the original office product
key (or serial number, I forget which) and we'd then find the Office 2007
download ISO hidden deeply on the Microsoft web site - and we'd download
that Microsoft-provided ISO, perhaps burn it to optical disc for re-use,
and we'd simply install Office 2007 on the new laptop from that ISO, and
we'd bring over the old key that we unearthed using Belarc Advisor.

In the end, you or I would have Office 2007 running on their one (winXP)
desktop and their one new (win10) laptop, which is within the license
constraints (I believe).

But that ain't gonna happen with these people.
They are not technical.
They can't handle the complexity.

Plus, it's time they moved into the new century, so, if they stick with
Office 2007 (which they continue to call "Word 2007", not realizing there
are multiple office apps), they will eventually have problems reading
Office 2013 documents.

So, it's time they got a new Microsoft Office suite.

Since they will *keep* the WinXP desktop with Office 2007 on it, all
we're looking at is a *single* license of Office 2013 (which they
continue to call "Word 2013", which means they're not using Outlook).

So, the price comparison is the following:
1. Pay $100 per year for Office 365 for the rest of their lives, or,
2. Pay $140 once, for Office 2013 H&S for the one laptop.

To me, unless I missed a step, it's a no brainer.
