I also have the same issue, however if I go under the network manager and disable the wireless, wait 10 seconds, then enable the wireless I am reconnected.
I am running 12.10 fully patched on an HP dc7800p with a Trendnet TEW- 423PI PCI wireless card. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1066404 Title: wireless connection drops To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1066404/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
