> Wireless with the BCM4312 adapter connects, runs several minutes, and disconnects unexpectedly with Ubuntu Jaunty (9.04) Alpha 4 on an HP 2133 MiniNote laptop.  The same laptop runs wireless flawlessly under Ubuntu Intrepid (8.10). I only have wireless issues under Jaunty. Once it has disconnected, I'm unable to reestablish a connection w/o rebooting.

> All this takes to reproduce is to boot Jaunty with the B43 driver, bring up wireless, and then wait 5 or 10 minutes. I've hit this at home, with WEP encryption, and at work on an open guest network so its not the AP. The wireless works fine for several minutes, disconnects, and then won't reconnect

> I considered loading a different version of the B43 firmware as suggested but the firmware stored under /lib/firmware/b43 is identical between Ubuntu Intrepid and Jaunty.
