I can confirm this bug. I seem to have the same situation as Christiansen on my Thinkpad T61. madwifi (ath_pci) worked for me over the past several Ubuntu cycles but ath5k never did (this has been the case at least since Hardy). I just upgraded to Karmic, which has no madwifi. ath5k behaves as in previous releases. I can specify an essid and scan for available networks, but dhclient fails to retrieve an IP for my network (see iwconfig example below). I have also tried connecting to my router with Network manager and WiCd, but had similar disapointing experiences with those when using ath5k (can see available networks but cannot connect). Wired connections work fine however. Thanks for all the hard work you developers are putting into making Ubuntu better!
