The key is the "a" as in 802.11a, which is 5 GHz only.

So, if it doesn't have "a" (all by itself and not with "ac"),
then it's not 5GHz? Is that correct?

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.

Broken link. Try:
http://reviews.costco.com/2070/10008...d-hp-envy-15z-
laptop-amd-quad-core-a10-backlit-keyboard-reviews/reviews.htm
which says:
802.11b/g/n WLAN
which is 2.4 GHz only.

This link worked for me just now:
http://www.costco.com/CTOConfigureCm...1&prodtype= 2

The WLAN card is listed as "802.11b/g/n WLAN [1x1]" which will NOT do
5 GHz.

If you must have Microsoft Office, look
at Office 365 or the various Office Mutations available.

Sad story. Long story. Experience. Nothing else is Microsoft Office.
You and I can handle any office lookalike program, but teachers can't.
Office 365 is stupid, for anyone buying only 1 copy of Home & Student,
and who is still using Office 2007, which means they'd pay for Office
ten times over with the subscription than with the one price.

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.

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
