I've been having this bug lately. Also on an Acer Aspire One, but running 10.10 NBE. Mine has an Atheros AR5001 wireless card.
Here is what was in the messages file in /var/log after the wireless drops Oct 20 21:00:15 AAO-Netbook kernel: [ 1106.381052] cfg80211: Calling CRDA to update world regulatory domain Oct 20 21:00:15 AAO-Netbook kernel: [ 1106.399980] cfg80211: World regulatory domain updated: Oct 20 21:00:15 AAO-Netbook kernel: [ 1106.399992] (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) Oct 20 21:00:15 AAO-Netbook kernel: [ 1106.400002] (2402000 KHz - 2472000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) Oct 20 21:00:15 AAO-Netbook kernel: [ 1106.400011] (2457000 KHz - 2482000 KHz @ 20000 KHz), (300 mBi, 2000 mBm) Oct 20 21:00:15 AAO-Netbook kernel: [ 1106.400020] (2474000 KHz - 2494000 KHz @ 20000 KHz), (300 mBi, 2000 mBm) Oct 20 21:00:15 AAO-Netbook kernel: [ 1106.400028] (5170000 KHz - 5250000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) Oct 20 21:00:15 AAO-Netbook kernel: [ 1106.400037] (5735000 KHz - 5835000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) -- Wireless connection is lost, cannot reconnect without reboot https://bugs.launchpad.net/bugs/372885 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
