I could reproduce this bug as described. If you try to add the correct network with wpa to the network manager with the edit buttons and type adhoc, it won't work, too.
So it's actually impossible to create or join(?) a secure adhoc network with ubuntu because wep is not secure, you know. I think it's a really dangerous situation...like a rope of sand. -- incorrect encryption detected when logging on to WPA ad-hoc wireless network https://bugs.launchpad.net/bugs/322902 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
