Have you tried the "backport" modules? In the past, the backported rt2x00 modules worked better for my USB dongle, thought I haven't tested it on Karmic.
$ sudo apt-get install linux-backports-modules-karmic-generic (A restart is required for the new modules to load properly). -- Edimax Wireless USB Dongle Failure Karmic Kernel 2.6.31-X https://bugs.launchpad.net/bugs/396417 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
