I have a problem. My wifi is sketchy at best. I'm wondering if anyone is aware of any tool out there that will allow you to use your wifi card to scan the 2.4GHz spectrum and assess/identify what is happening.
Allow me to explain my dilema in deatil so you get what I mean:
I have a linksys wrt54g
wifi router. I also have an IBM ThinkPad T40
with built in wifi(centrino), an intel pro wireless 2100
. I run Gentoo Linux
On average they are about 3-4m apart. I have a one bedroom apartment so I only travel so far with my laptop.
Constantly, and I mean constantly, my connection is very unpredictable at best. Not all the time, but it happens in spurts up to an hour at a time.
What I want to do is find something that will allow me to analyze the 2.4GHz specturm with my wifi card so I can see what is going on.
Using /proc/net/wireless stats I see that my Rx signal level is between -40dBm and -50 dBm, decent. however my "link quality" fluctuates all over the map. I want to konw why?
Is it a micowave? A cordless phone? Something else that uses the 2.4GHz ISM band? I want to know.
00:52 You might also try changing the channel
00:52 ahh, thought of that
00:52 I'm on 1...
00:52 It seemed to help when i had that problem
00:52 and I'm there because when I moved in I scnanned the specturm
and found a shitlod of defaults at 6, and then 3 others on 11
00:52 nothing on 1
00:53 I usually scan the area once a week to seee what's out there
00:53 now there 2 others on 1, 3 on 11, and the usual boatlods of
defaults on 6
00:53 i can see about 25-30 other AP's fome my apartment
00:54 so I've look at that wuite a bit
