Since @PaulaBean's gone AWOL again:
http://thedailywtf.com/articles/getting-wired
Paging @mark_bowytz.
Admin
Because you can't have WiFi and Ethernet in the same computer at the same time.
Now, TRWTF is doing this sort of stuff all-at-once instead of progressively.
Admin
NO NO NO. TRWTF IS ATTACHING DESKTOP PCs TO WI-FI.
Admin
But look, no wires! Except that black powered one, the USB one, one for the screen mounted on the wall...
Admin
Unless you are in a place where you can't run network cables...
Admin
True. But that place had network cables everywhere.
Admin
TRWTF is using USB WiFi adapters. :trollface:
Admin
And how would you have extended PCI adapters?
That's why all of my components are USB. My graphics card is 10 metres away from my PC
Admin
@Jaloopa, is your graphics card really 10 metres away from your PC? Why?
Admin
Ventilation

It's outside the window and sitting in a snowpile for better cooling.

A few years ago I was involved in what was to be the largest single wireless network. New York City Schools - All Buildings. Forget the exact numbers but computers approx. 250K, Buildings in the thousands, Access Points approaching 50K....
Even back then, "good" access points monitored their signal as well as other access points to automatically adjust the radio power level to avoid the situation.
So add just one more WTF to the article, of them not selecting quality access points, and instead resorting to the "wired wireless" solution.
Admin
You have to keep it on the windowsill, snow does nasty things to the electron-majigs.

I found TRWTF:
He should have had his resume updated and out the day he heard about the plan and that anybody who pointed out the obvious errors would be fired. WTF is the point in waiting for the obvious failure to strike, wasting your brainpower thinking of a way around the ridiculous restrictions, and only after that, thinking about looking for a job that isn't insane?
Admin
By running an extension cable between the adapter and the antenna, naturally.
A metre or two of 50 Ohm RG8 should do the job nicely.
Of course, if you bought PCI adapters without removable antennas then your name is Andy and you deserve whatever happens to you.
Admin
Bear in mind that anything up to 99.99% of an article on the front page is made up of whole cloth....
Admin
Hell, I'm fairly certain this wouldn't even actually work.
Admin
+1
I believe you can still get those through Radio Shack.
Admin
RG-8 seems like a bit of overkill. It's rather stiff and awkward to work with compared to, say, RG-58, and the loss at 2.4GHz of 2m of RG-58 is only about 2dB vs. about 1.4dB for RG-8 — not a big difference.
Admin
That doesn't help when all the clients are blasting out 30-35 dBm each with no regard as to what the others are doing. Contention isn't due solely to nearby APs, but also due to clients stomping on each other in an attempt to communicate with the AP.
Admin
As a person who has designed a wireless network or two in his day...that percentage seems a bit low...
Admin
That's when you implement physical TDMA by segregating each wifi adapter into a mini faraday cage and building a mechanism to rotate the AP's antenna through each section in the cage in sequence. :stuck_out_tongue_winking_eye: Bam! Everyone gets a few seconds of 100% access at 54 Mbs, right? :P :P :P :P :stuck_out_tongue: [spoiler]No. No it does not. At all.[/spoiler]

Not for long...

Missed opportunity to have NUTS as the acronym.
Admin
Hmm, that was my intention, but it either got edited out or I forgot what I was doing.
Admin
NUTForce is neat, too.
Admin
Now stop and think....putting all of the adapters physically close (allegedly) helped. That would contraindicate your position. In fact the "with no regard as to what the others are doing" is the basic flaw in your logic.
Admin
Probably could have just gone around and powered down 75%? 80% of the WAP rather than making a rat's nest.
Admin
Not for long...

Nuts - you beat me to it

Where you can't run network cables... but where you can run power cables? I'm sure such places exist, but truthfully it's a very narrow scope. I mean, we're talking WiFi for desktop PC, not cellular service or WiMAX for some sensor out in BFE. Just how far from civilization are you expecting to put your PoE 802.11 AP?
In my experience, wireless desktops exist where network drops could be run perfectly fine, but people decide they don't want to pay to have them pulled. It's particularly fun because then they complain about signal problems. They pick an inherently unreliable connection method, and then complain that the connection is unreliable.
I worked with a school cafeteria where they had no name 2.4 GHz handsets, several microwaves, and the students have issued iPads, but they still insisted that the PoS systems be wireless. Getting a wireless signal in the middle of lunch was a joke. 50 student devices connect to each of the 3-4 APs every lunch. About the same number tried to connect and would time out. The ancient microwaves and handsets acted like signal jammers, forcing everybody to the 5 GHz band every few seconds. They tried to blame us for it. Nope, sorry. You were warned and you did it anyways. We told you wired network was a requirement. You opted for wireless anyways.
Admin
I'm still entirely unclear on how they got a "federal grant" to switch their network to wireless.
Admin
If you're dealing with a rental scenario where you can't drill holes, running cable suddenly becomes quite a bit harder, especially if you have to traverse between floors...
(My house fits this description, for instance.)
Admin
Then why have the 2.4 GHz WiFi at all? Most devices are capable of 5 GHz these days. I get better signal on 5 at home sometimes too and I live in a house in the suburbs with nontechnical neighbours (few other networks).
Admin
Heh, you're not trying hard enough! :) I've drilled holes in plenty of rentals and never got pulled up for it.
Admin
And of course, all stories happened yesterday.
Admin
I was replying to someone talking about iPads jumping to 5 GHz because 2.4 was getting interference from microwaves and ancient handsets. My suggestion was to just turn off 2.4, at least around the cafeteria to stop clients jumping between bands. All iPads support 5 GHz so it's really a cow's opinion.
Admin
Putting them physically close meant they were all broadcasting from a single location instead of distributed across the entire area and suddenly all the hidden nodes disappeared as every client of an AP was right next to every other client of the AP.
That doesn't contraindicate what I said.
Admin
Ah, college days... and toothpaste.
Admin
I am always amazed by these people who think that anything they come up with is genius and anyone who disagrees or points out that they could be wrong is a threat that needs to be fired. You would think that an intelligent human would understand they don't know everything, that's why they hire people who do. If you hire someone who knows more than you and you dismiss everything they say, why the hell did you hire them in the first place?
This mentality shocks me that people in business can be that stupid so frequently.
Admin
Money, my friend. As long as you're getting paid, who cares? Plenty of people think that way.
Admin
I think laws mandating meaningful shareholder democracy would help. Right now often no one has an incentive to care.
