Clare--I want to make something clear. I am having a problem with the
fellow who is asserting that if you run a CAT6 cable to your garage
you end up with fire and brimstone coming down from the skies, rivers

dead rising from the grave, human sacrifice, dogs and cats living
together . . .

I have never known _you_ to give advice regarding network that was
other than sane and straightforward.

If he only got 2 Mb/sec out of modern Ethernet he's got a computer in
the middle there purposely designed to be a throttle.

Gigabit is just not that fragile. It has been shown to run on barbed
wire.

8 strands of barbed wire I assume?????

Yep.

https://www.wband.com/2002/05/wideba...onal-magazine/

IIRC Broadcomm was demonstrating their interface chips--they did a
similar one with 100baseT a few years earlier.

That was specific to WideBand Corps implementation of 1000Bt
networking. Not everyone's implementation was as robust!!!

It will NOT downgrade it's speed as required to maintain connectivity.
Instead it will fail and retry, and fail again, untill it manages to
successfully pass the packet. This will NOT result in gagabit speeds -
likely even less than 10BT speeds.

I was having trouble with the computer I am using right now.

Periodically Internet access would slow to a crawl. Speed was all
over the map. The network connection would drop from gigabit to 100
mbit. Speedtest would show speeds as low as 5 Mb/sec but usually more
like 50 and sometimes back up to 300 (limit here is my ISP).

Finally tracked down the problem. There was a patch cable that had
gotten walked on, had furniture run over it, been gnawed by rodents,
and was in a few spots there was bare wire poking out,. Sometimes it
was _still_ carrying 300+ Mb/sec.

It's not as fragile as people think it is, at least not when it's
being run in a typical residential environment where runs are,
compared to what the spec allows, quite short. If you're working
right at the limit of what it can do, where signal attenuation is
piled on top of everything else it's another story, but that doesn't
typically happen in somebody's house.

You want to try in a 300 ft long building with various itterations of
cat5/cat5e cabling running both bundled and helter-skelter, some in
troughs, some not - running both over and beside flourescent lamp
troughs, down walls behind service panels, under floors, over
suspended ceilings, with "noisy" led lighting, you name it - with
servers and switches in 2 different areas of the building, with 2
separate networks interlinked (one data, one voip) and other
challenges.
The voip was POE 10/100 - the data mostly 1000BT.

There is a reason IT techs like myself keep our hair cut short!!!!

I also still have a few routers, switches and stuff, Cisco commercial
products, wanna buy them and get them off my hands?


I've got gigabit stuff that's technically obsolete too - but would
still make someone a DANDY network

About $20,000 worth, at the very minimum when new - and it is NOT
CISCO.

The devil in me wants to say "good decision".

I suspect that they are well and truly obsolete.

In any case, nobody is going to be running a T1 from their house to
their garage on a CAT6 cable. What's going to be running on it, in
2018, is gigabit Ethernet.


Or even. more commonly, a 100Mb connection (still WAY faster than
most internets)

A couple of years ago I'd agree, but at this point any computer you
buy has gigabit and the local Best Buy doesn't even have any switches
that don't support gigabit--the cheapest is a 5 port for 30 bucks.

Of course not, the switchgear costs alone would be prohibitive, plus
the cabling. But he could run fiber optics and never have any of the
problems associated with hard wire systems.

What would justify the expense?

The only thing that would justify fiber to the shop is EMI issues -
and they would have to be BAD - unless you just happen to have a bunch
of fiber net equipment gathering dust in the "sandbox" and you want to
play - - - -

Yep.

If my creds are so important to you then you can call Cisco and see
what all I was certified for at the time. I am not keeping my certs
updated because I am retired. Get it?

And the equipment is leaving you WAY behind as well.
I never got CISCO certified because you could go broke just
maintaining currency with their new product.

I did not say "creds", I said "cred". You're topping it the expert
here when it's clear that you are far from up to date.

I'm basically "retired" for a year and I know I'm already far from up
to date with current technology.

I'm not retired but I've been away from the networking world for a
long time, still, knowing what a CAT6 cable actually looks like when
you cut it open is pretty basic. Where I get lost these days is with
all the wifi variants and the 10gig stuff.

I gave up trying to keep up 5 years
ago when I offloaded the network management to a third party
consultant - who also prooved to be less than current and has now been
replaced by a larger and more proficient network consulting/management
firm. I wouldn't know where to start with the current setup in the new
insurance office facility. It's all enterprise grade stuff surplussed
out from Blackberry's downsizing - well over 1/4 million dollars worth
of network switches, routers, servers etc

The "obsolete" gear I have sitting here is what came out of the 2
offices when they moved in together in the new facility - virtually
all less than 5 years old

Explaining or rationalizing why it is important to do it right in the
first place.

What is "right" and what is adequate to the task are two different
things.

Overkill in IT installations is RAMPANT - particularly for home
installs.

Precisely my point. For this situation I would either use wifi to
begin with or run a direct-burial cable (note that in my location the
town will be on you if you run an overhead cable).

Well that's all well and good. So how much measured degradtation have
you experiences in wires run from people's houses to people's garages
carrying gigabit?

I didn't do houses expect for friends. But the ground field for the
bldg is a big issue in such cases which I addressed in another post.

Apples - oranges - Turnips.

Yep. Spreading FUD. "You're gonna get electrocuted because you ran a
CAT6 cable to the garage". So why don't you get electrocuted when you
plug in the hedge trimmer to the outlet in that same garage?

Yeah, you addressed it but didn't give any reason to believe that you
are familiar with transformer-coupled network interfaces which are
standard with modern Ethernet but apparently didn't exist the last
time you dealt with Ethernet.

If I gave you my full resume from all the years I've worked you would
probably call me a liar too. Oh well. what's a guy to do?

I don't care about your damned resume. You remind me of the mainframe
types who have been in IT for 50 years but can't figure out how to
work Excel.

About 27 years and I'm already a dynasaur - and I've never been
involved with anything outside the IBM compatible PC world, except for
the old 6809 Tandy world. (a bit of Banyan Vines, a bit of Unix Xenix,
a bit of Nohell, a touch of OS9 on the 6809 Trash80) - but
functionally illiterate outside the MS DOS / Windows world.

It's hard to keep up with all of it. The sad thing is that the kids
running it today seem to be lost. I suspect that there's going to
come a time when I bring my cable analyzer to work and show the IT
people what's wrong with their damned network.
