Public bug reported:
When I attempt to connect to any wireless network using wicd , during
the "get ip" stage the status bar is filled with hex jibberish, the
operation times outt, and I cant connect. I look in dmesg I see the
following crash , I think it happens before wicd is used. When I attempt
to connect I get more "deauthenticating from XX by local choice
(reason=3)" messages. Doesn't alway crash, but almost always.
What can I do to get my wifi working??
