Ubuntu 7.04 has a major regression related to the bcm43xx card and NetworkManager. Unfortunately it also found its way into Cassandra. I filed a bug here: https://bugs.launchpad.net/ubuntu/+sour ... bug/110459 It's filed against Kubuntu, but it doesn't matter which variant- the NetworkManager daemon doesn't work with my bcm43xx card. It worked almost perfectly before in 6.10 and also in Linux Mint KDE 2.2.
Basically the problem is that the NetworkManager just hangs while trying to connect. Sometimes if I unload/reload the driver or disable/enable the WiFI radio I can coax it into connecting, but it's very unpredictable. Somewhere I read that this seems to be the case only when the connection is open, without encryption, as is the case with me. Ubuntu is not doing anything about the bug. I hope maybe somebody here has a solution for Cassandra?
Thanks a lot!
