I seem to have the same issue with Lucid. I'm using a Netgear WNDA3100 USB dongle which works using the ar9170usb driver. After some time (from 5 minutes to a couple of hours) the connection will drop and scanning for wireless networks will produce no more results. In my case, rebooting has no effect. The thing that cures the problem is unplugging the USB dongle and replugging it - voila, instant connection.
I believe this is due to Network Manager. Uninstalling network-manager and network-manager-gnome and configuring wpa_supplicant by hand has given me a stable connection since this morning (it's never lasted this long so far). -- Network card keeps dropping the connection https://bugs.launchpad.net/bugs/525902 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
