Linux Wireless Networking issue

I have a dell inspiron 630m running fedora core 4 (kernel version: 2.6.11-1). I have installed a driver for the wireless card (something like a Intel Corporation PRO/Wireless 2200BG). I had it working well for a while but I messed around with the software settings and it stopped working. It would not be able to detect any networks even when others could.

$ iwlist scan
eth1 No scan results

I cant figure out what is wrong with it. Heres iwconfig:

$ iwconfig eth1
eth1 unassociated ESSID😱ff/any
Mode:Managed Channel=0 Access Point: 00:00:00:00:00:00
Bit Rate=0 kb/s Tx-Power=off
RTS thr😱ff Fragment thr😱ff
Power Management😱ff
Link Quality:0 Signal level:0 Noise level:0
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0

If anyone has even the remotest idea I would be glad of help.

Does your network have wep enabled? Not quite sure how to connect to an ap through the command line; Suse's yast set up my wireless card with a few clicks. Which distro do you use?

Umm...there are no profiles with iwconfig. Unless you use a wifi progile program, you will lose your wireless settings after a reboot.
 
You can create a init script for WPA_Supplicant to load at start up and set your IP address, or even using iwconfig.

Make sure you have your antenna on btw, if I remember correctly it doesnt have the ability to turn on the WiFi led due to a driver issue with ifconfig, though it was experimental and may work now if enabled....

I put windows back on my Inspiron 6000(Gnome refused to finish compiling 🙁 ), or id check for you, if all else fails recompile it from source, starting with the ieee80211 subsystem, then ipw2200 driver, and then wireless tools, make sure to get the firmware as well.
The driver works pretty well, and if it is an unsecured AP it will automattically connect if memory serves me right, though I don't see a radio off message I can't remember if it tells you through iwconfig or iwpriv.

Couldn't even imagine what happened based on "messed around with the software settings", or even suggest how to fix it, you can also use the uninstall the rpms and reinstall them if that is the method you like.
There is not much in the way of settings for the drivers, in my experience they either work or they don't, there arnt that many settings that could cause everything to break.

BTW anyone know if they have fixed the ipw2200 + WPA_Supplicant = no dhcp?
 
Thanks for the help...
I dont really want to recompile the drivers. The antenna off might be what all my trouble is. Only problem is I dont know how to turn it on.
Also, I am pretty sure the wireless card does not need an IP address to scan for possible networks. But I think I am going to give up on
wireless for a while, it isnt all that necissary for me.

Do an lsmod. You should see ipw2200. If not, then modprobe ipw2200.
Then see if you can get an ip address: dhcpcd eth1.
ifconfig to see if you got an address.

Uh fixed? I've never had a problem with it. My laptop uses ipw2200 and at home I use wpa_supplicant to connect to my LAN via dhcp. It's always worked for me (a little over a year now).

Opps I should have mentioned that it was a preticular issue with some Dlink access points with it.... but it was completely solid otherwise, never dropped the connection 🙂
