Public bug reported:
I just purchased a Thinkpad 410s which for the most part Ubuntu works
with fantastically out of the box (suspend and hibernate both work, 3D
works, sound works). But the wifi occasionally gets disconnected, and
when that happens it becomes impossible to reconnect without a reboot --
network manager will ask for the key as if it had been rejected, and
then if I click ok it will try for awhile and eventually say I'm
disconnected. I primarily have seen this when connecting to a WPA
protected network, but I believe it's also happened on an unprotected
network (where it doesn't ask for a key obviously but still can never
reconnect).
I played with toggling networking/wireless in the network manager
context menu but it didn't have any effect on whether I could reconnect.
The laptop also has a physical switch for turning the wireless on and
off, but it made no difference either. Here's the identifying snippet
from lspci for my card:
