Could be also an 2.4GHz wireless (home) phone... I have one that if I use that to make a (landline) call, my tablet and home computer will drop off their WiFi connection and can not connect as long as the phone call is active. (I'm not using that phone any more... but use my ancient 900MHz phone that coexist with my WLAN without any interference...)

LOL Mara... my mom's microwave oven kills Dad's gaming wifi. You should hear him and my brothers holler when someone fires it up-- adios, Halo match!

(and hello from Helsinki!)

How is it over there? We are about to enjoy same weather here than you have over there...

EDIT: Shouldn't you be at sleep right now?

(Sorry, off topic...)

It's cold of course, and light but steady snow.

I'm trying to sleep-- timezone change messes me up. Only 3 hours sleep last night... shooting for 5 tonight. : /

With wirelesstools you can also use the command 'iwlist wlan0 scan' which will give just a simple list of what AP's it sees and their channels and ESSID.

EDIT: On the NIT the above only works when you're connected to an AP, unlike with most Linux wi-fi drivers where you can run the scan command before you connect. Still useful on the NIT though, except for the OP I guess as the problem was it wasn't possible to connect in the first place due to the router clashes.

EDIT2: All these scanning- and probing commands/tools/programs have the risk of stopping the wi-fi working altogether, requiring a reboot to get wi-fi working again. At least on OS2007.

Most WAP manufacturers recommend at least 3-channel separation to avoid interference.

I had a similar problem with my very-old Linksys getting over-powered, too, so I updated to a more modern wireless router.

I still had some problems which I traced to a system across the street from my house trying to establish a "network bridge" to my system. I complained about it to the homeowner and the problem went away.

ok.
to Mara & Texrat: I don't think a phone or microwave will have their own SSID !

I installed wirelesstools but when I run airodump-ng as root it just says "comand not found".
Anybody knows where wirelesstools are installed to so I can go to the directory ?

Haven't tried NetStumbler yet. Have to dust off my old laptop and install it there at home and then bring it to the office. (haven't used it since I got my N800.)

The router is a linksys WRT300N.

These are the apps in the official wireless tools distribution
http://www.hpl.hp.com/personal/Jean_...nux/Tools.html

* iwconfig manipulate the basic wireless parameters
* iwlist allow to initiate scanning and list frequencies, bit-rates, encryption keys...
* iwspy allow to get per node link quality
* iwpriv allow to manipulate the Wireless Extensions specific to a driver (private)
* ifrename allow to name interfaces based on various static criteria

my usr/bin directory shows:

iwconfig
iwevent
iwgetid
iwlist
iwpriv
iwspy
ifrename

True. Mine was a side comment, sorry.

I think it's time to get a new router. If you can't receive it from 3 ft away, it's just not working. They do fail, with regularity.
