I am having the same problem, on a Dell Latitude CPxJ. It has a PCMCIA Prism54 card (Gigafast WF728-AEX) worked fine on Edgy.
Upon upgrading to Feisty, the card is recognized, and can scan for APs, but does not associate. dmesg shows: [ 42.764000] p54: LM86 firmware [ 43.800000] wmaster0: Selected rate control algorithm 'simple' [ 43.992000] wiphy0: hwaddr 00:0a:e9:08:69:86, isl3880 Then several occurrences of this error as well: [ 142.420000] eth0: starting scan [ 142.480000] wiphy0: frequency change failed [ 142.540000] wiphy0: frequency change failed [ 142.600000] wiphy0: frequency change failed [ 142.660000] wiphy0: frequency change failed [ 142.720000] wiphy0: frequency change failed [ 142.840000] wiphy0: frequency change failed [ 142.900000] wiphy0: frequency change failed [ 142.960000] wiphy0: frequency change failed [ 143.020000] wiphy0: frequency change failed [ 143.080000] eth0: scan completed I will attach the relevant info in subsequent comments. ** Attachment added: "dmesg.txt" http://librarian.launchpad.net/7563338/dmesg.txt -- Feisty wireless broken after update https://bugs.launchpad.net/bugs/105357 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
