I also have this problem. Wireless keeps disconnecting, seemingly at
random - once it disconnects, it is unable to reconnect again (although
the panel icon suggests that it is trying). The only way for me to
connect again is to disable wireless in NM and enable it again.
I've tried the vesa driver fix and it didn't help at all, the behavior
is completely the same. Running the vesa driver right now and was just
disconnected.
I've also tried downgrading the NM, currently running at version
0.7~~svn20081018t105859-0ubuntu2, again, to no avail.
This behavior started after upgrading to Jaunty.
Some info (if you need anything else, I will be more than happy to
provide it, but please, explain how to get to it first - I am still a
Linux newbie)
