Wireless works - only if router security is turned off!

OK, I’m a longtime openSUSE user (servers) – and am now trying it out on an IBM laptop with a Cisco Aironet card.

openSUSE 11.1 with KDE 3.5

Wireless works fine as long as I turn off security at my router. When I turn on WPA2 Personal security I end up with the following:

First, the iwlist command:

linux:/home/chris # iwlist scan
lo Interface doesn’t support scanning.

lo no wireless extensions.

eth1 no wireless extensions.[/FONT]

So, why is it losing the essid and access point? When I check the NetworkManager log, it says that eth0 timed out when trying to associate.

I tried switching to different channels, and I also tried changing all the permissions in the knetworkmanager.conf and NetworkManager.conf files from deny to allow. No luck.

Like I said, when I turn wireless security off at the router everything works fine. When I turn it back on, it fails. I copied/pasted the 64-hex digit key to a USB stick so there would be no chance of error in retyping it – I’m just copying/pasting it into NetworkManager.

Please help. Five hours of my life has just slipped by :’(

Linux driver for that card does not support WPA(2).

:open_mouth:

ok, that would explain it - thank you!

So, I assume if I switch to WPA instead of WPA(2) it will work (?)

Try and you’ll know.

As I don’t have any further information on the hardware in question (PCI-ID, name of kernel module in use), I also could only guess.

well, turns out that I could not get WPA to work, either.

Looks like only WEP will work. I’m using 128 bit keys.

(edit: I did a quick google search…WEP is way too weak…not good)

Thanks,
