Having same issue. As reported by other users, I did not have this problem w/ Jaunty. Disconnects when connected via WPA2. Disconnects during downloads.
Oblivious to hardware make/models, but laptop is a Sony VGN-NW240F. Sometimes Network Manager reconnects automatically, but most of the time I'm prompted for WPA key. When at home I type it in, when I'm not at home I have to restart. Sometimes key is accepted, but most times I have to restart. As already expressed by others, this is an extreme pain in the rear. Just now (reason I looked for a solution) it has disconnected like 10 times while I try to DL a Linux Mint .iso. -- [Karmic] wireless connection keeps dropping - WPA TKIP https://bugs.launchpad.net/bugs/481432 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
