Update/Upgrade killed WPA wireless network (again!)

[siloko]

Hi all,

Updated my 8.04 install and it killed my wpa encrypted wireless network - ok connecting to open networks or using a network cable.

Decided to bite the bullet and do a dist upgrade to 8.10 to see if it sorted it out - no luck.

The 8.04 update has caused problems with wpa before. I generally use Network Manager to administer my wireless, although to try and debug these problems I dropped down to using wpa_supplicant from the commandline.

If anyone has a clue as to what is going wrong I have all the relevant output here:

http://mango.homelinux.net/wlan_debug

iwconfig output is here: http://mango.homelinux.net/wlan_debug/iwconfig.txt
ifconfig output is here: http://mango.homelinux.net/wlan_debug/ifconfig.txt
wpa_supplicant output is here: http://mango.homelinux.net/wlan_debu...ant_output.txt
and my wpa_supplicant.conf is here: http://mango.homelinux.net/wlan_debu...icant.conf.txt

My call to wpa_supplicant is:

sudo wpa_supplicant -Dwext -ieth1 -c/etc/wpa_supplicant.conf -dd


Any help much appreciated

What wireless chipset are you using?

Can you post
lshw -C network
iwlist scan
lspci -nnm

Thanks

Hi,

Thanks for the reply. I have posted the output of all commands you asked to the same place:

http://mango.homelinux.net/wlan_debug

The device is a standard built in intel wireless card, using the ipw2200. Incidentally I have tried wpa_supplicant passing the proper driver but it uses -Dwext anyway, as I think it has support for more recent functionality/attributes.

Interested if this shows up anything weird because my setup is pretty standard and must be used by thousands of others!

Cheers

Ok so this is a bit embarrassing but . . . well firstly I am sure the update to my Hardy install killed my wireless but it's possible the upgrade to Ibex sorted it out . . . however in the meantime I had changed the wireless broadcast channel to 13 (as I am in Europe) and just found out:

dmesg | grep 2200

returns

ipw2200: Detected geography ZZM (11 802.11bg channels, 0 802.11a channels)

giving me only 11 supported channels - so no matter what I did I was never connecting to my network on channel 13. So I dropped down to Channel 1 and all was well!

Thanks to whoever looked at this, apologies for wasting your time
