I programmed my own Linksys routers with OpenWRT so they aren't
representative, but I found that they would sometimes go offline when
traffic was heavy and require manual reboot. So I wonder if whether
your wifi router is rebooting could be tested by seeing if two
connections to it would be lost at the same time?
That's an interesting idea, thanks. In the meantime I'm rummaging
through syslog to find out what AP MAC addresses the wlan0 interface has
been authenticating with. Seems the last authentication timed out and
it then authenticated with a different one. If that sticks it will be a
pretty good clue that the first AP is bad.
By the way I figured out how to get a ssh reverse tunnel going so I can
keep tabs on it from home. :)
So maybe the bad AP reboots and the disconnected netbook connects to a
more distant AP. Then the bad AP comes back online and the netbook
reconnects, but before the bad AP was really ready so the connection stays
dead until the networking is restarted on the netbook?
Reverse tunneling is lots of fun, especially with the -X option. It's
like having a computer while getting to give it away too! :)
