Public bug reported:
Binary package hint: network-manager
Bug:
Wireless connection becomes lost and the wifi message "Authentication required
by wireless network" keeps reappearing for no apparent reason. There is no way
to reconnect other than restarting the computer.
What should have happened:
The wireless network should stay connected.
What happened instead:
The wireless connection stopped working and returned an error message that
can't be resolved unless the whole system is rebooted. (Logging out and
logging back in doesn't fix the problem.)
Distro: Ubuntu 9.10 Karmic Koala
Package: network-manager
Wifi Device: Linksys WUSB54G
uname -a:
2.6.31-15-generic #50-Ubuntu SMP Tue Nov 10 14:54:29 UTC 2009 i686 GNU/Linux
More info:
The message "Authentication required by wireless network" keeps reappearing for
no apparent reason. I had already set the saved password in Network
Connections -> Wireless so it should remember it. Yet even after it connects
successfully on a reboot, a couple hours later it will lose connection and then
ask for the same password again.
However, retyping in the password in that error window doesn't fix the
problem. And when the user goes to the wireless icon on the Top Panel
and clicks "Connect to Hidden Wireless Network", there is no way for the
user to click on the final "Connect" button since for some reason it's
grayed out. I have attached 2 pictures showing the problem.
Here is the Log info:
