I experience similar behavior on a Dell D610 laptop with the ipw2200 driver connected to a WPA2 network. I have not tested using just plain WEP.
Sometimes I can get the network working without totally needing to reboot, and sometimes not. What I try to do is: # killall -9 NetworkManager # /etc/init.d/dbus stop ubuntu$ gnome-keyring-manager # /etc/init.d/dbus start I restart dbus to get NetworkManager back into shape. gnome-keyring-manager has to be restarted as my desktop user otherwise when network-manager restarts, it will asks for the WPA2 key again because it can't access the previously stored values. -- Network Manager becomes confused by sleep https://bugs.launchpad.net/bugs/158338 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
