I have a similar kind of problem. Updated from 8.10 to 9.04 dev, now Network Manager tells just that wireless is not available (it's grey). However, iwconfig shows I've wlan0, and I can manually setup the connection just fine (via iwconfig or /etc/network/interfaces & ifup).
Usually when one has wlan0 in /etc/network/interfaces, network manager skips it (or has the behavior changed?) so that it's manually managed, but no matter if I remove it or add wlan0 to interfaces, network manager does not give an access to wireless. On the time of update, there was no wlan0 in the interfaces file. So far, I have no idea what's wrong, or what other aspects besides the interfaces file could affect this. -- [jaunty] Network Manager no longer sees wireless networks https://bugs.launchpad.net/bugs/337076 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
