I've done a bit more work on this to see if I can get everything in. If I do a manual configuration, switch off roaming mode and enter the SSID details by hand then I can get an association and the network works.
Process to reproduce: Restart access point. Restart laptop in roaming mode. Login. Fire up a terminal running 'iwevent' and 'tail -f /var/log/daemon.log' Enter incorrect WPA password. - Network manager will now try and associate with access point, and eventually ask for a new key (usually in a minimised window which is annoying). Enter correct WPA password. - Network manager will log an assertion failure 'nm_utils_supplicant_request_with_check: assertion 'ctrl !=NULL' failed. This comes after a 'Error opening supplicant global control interface' earlier on. - Association fails. - (You get the same association failure without the assertion fault if you enter the correct WPA password first time). Select manual configuration and enter 'network admin' password. Switch off roaming mode on the wireless and select the ESSID from the drop down list. Enter the correct WPA password and select DHCP configuration. - Access point will associate correctly. Go back into the wireless configuration and switch 'roaming mode' back on. - Once network manager wakes up, it will associate correctly with the AP (and probably ask for the WPA password again - probably with a window in the background or minimised). If you now reboot the machine, then network manager appears to work correctly (although it doesn't retrieve the WPA password from the keyring - you have to enter it again). Multiple reboots appear to have the same effect until the AP is restarted -- [Gutsy]Network Manager Applet can't connect wireless with ipw3945 driver https://bugs.launchpad.net/bugs/121439 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
