I've been having similar issues under jaunty and karmic. It's hard to tell if this is the same issue or an independant one.
I'm on a bcm4322 wireless chip with broadcom's wl driver. I frequently lose wireless connectivity, and nm-applet doesn't indicate it. As far as I can tell, this is always on a network with many access points, one or two of which are clearly the closest ones. The system itself seems to be aware that it's lost its connection, as the logs indicate. It seems like the network roams from one AP to another, and gets disconnected, reconnects and authenticates, but doesn't run dhcp. Then, if I manually try to reconnect (by re-selecting the network in nm-applet, which already indicates it's connected) it fails to connect. The only reliable way I've found to correct is whenever the issue comes up, running: sudo killall wpa_supplicant dhclient; sudo /etc/init.d/NetworkManager stop; sudo rmmod wl; sudo modprobe wl; sudo /etc/init.d/NetworkManager start. I'm attaching a daemon.log with NetworkManager and wpa_supplicant messages. ** Attachment added: "daemon.log" http://launchpadlibrarian.net/31552629/daemon.log -- network manager frequently disconnects from secure networks in intrepid https://bugs.launchpad.net/bugs/294905 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
