after more testing, it might be that the problem is not really with NetworkManager.
i installed wicd (which uninstalled NetworkManager), and there it was much easier to see exactly what is happening. when i set my access point to "not-hidden" mode (broadcast SSID), then i was able to connect to the WPA1 network. when i set it to hidden, i was not able to connect to it anymore. in fact, wicd claimed the network does not exist. normally at this point i would be suspicious about the access-point, that maybe it's just broken, but i am able to connect to it's hidden WPA1 network without problems from the suse-linux-enterprise-desktop-10, which is preinstalled on the laptop. -- unable to connect to WPA-protected network https://bugs.launchpad.net/bugs/336230 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
