Public bug reported:
PROBLEM
After an apparently-random amount of time, the network connections icon
will simply disappear. An active wireless connection will also be
terminated at this time.
A wired connection will continue to work. Upon unplugging the ethernet
cable, no wireless connection will start up. I have not noticed if the
icon remains up until the wire is unplugged or not.
This problem started at some point after I had upgraded to the Natty
beta.
HOW TO REPRODUCE
I am not sure. Information about my wireless chipset should be attached.
If it is not, please tell me what further information is needed.
EXPECTED BEHAVIOR
Upgrades will not cause regressions in wireless network performance.
