Bug Description
SRU justification:
Impact: In order to have the wireless drivers from compat-wireless living beside of the ones that come with the stock kernel (or ubuntu modules) the mac80211 stack gets modified, so the exported symbols are unique and also the module names for the stack get prefixed. The modification missed out some request_module calls where the stack tries to get certain cryptographic algorithms (wep, pkip, ...). These calls still request the modules from the base package. However the loaded modules will not interact with the modified stack. This results in being able to see access points but always being asked for the passphrase.
Fix: Adapt the munging script to find and replace the requested module names.
Test: See bug report. Unable to connect to an encrypted AP with drivers from LBM (ipw2200 in that case).
My Dell Inspiron 9300's wifi stopped connecting to my access point with kernel update 2.6.24-22. I am able to boot with -21 and have working wifi. Later kernel updates have not fixed the issue either (the latest one I have is -23).
Symptoms: Network Manager applet shows it is trying to connect to my access point, and sees it and other access points around as well. But rather than connect, it asks me for my WEP key info after a while, then tries for a while, asks for WEP info, ad nauseam. In that sense it looks like https:/
My writeup of my system is here: http://
Will attach other info.

What encryption is the AP running? The log shows only WEP being loaded. I got the same network card here running with the latest Hardy kernel and can still connect to my AP (WPA). However I can see the tkip algorithm being loaded. Could you please also attach the output of lsmod? Thanks
