I too got broken wireless upon upgrade to lucid. It was an USB dongle using driver rt73usb. Simptoms were the same deauthenticating barrage of messages, and mangled essid.
Following the clue of a previous reporter, I saw that I too had network- manager installed, albeit I use wicd. Killing the process (sudo service network-manager stop) didn't work. Uninstalling the package, however, did it even without rebooting. -- Wireless connection frequently drops [deauthenticating by local choice (reason=3)] https://bugs.launchpad.net/bugs/548992 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
