Ah, thanks Cerowain. Yes, after commenting out *every* line that mentioned the wireless interface (ath0 in my case) in the file /etc/network/interfaces, and saving the file, the gnome-keyring prompt box popped up. I rebooted and logged in again just to make sure, and wireless was back in business.
It seems from the forums that Network Manager will leave alone any interfaces mentioned in /etc/network/interfaces and not try and manage them. There is, no meaningful documentation on such details on http://www.gnome.org/projects/NetworkManager/ I did a dpkg -S interfaces to see which packages owned a file with "interfaces" in its name, but there was no package that admitted to owning /etc/network/interfaces. Presumably it must have been created/mangled dynamically by a postinstall script on one of the packages that was updated on the night things went wonky. Whatever package mangled the file should be blamed for the bug I guess, but there's no way to find out what that might have been. -- gutsy: wireless non-functional after update https://bugs.launchpad.net/bugs/141394 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
