More details on situation encountered on IBM Thinkpad T60 w/ Intel wireless 3945ABG
card used to deauth itself (but still appear connected according to the network manager applet icon) Telling nm to reconnect to the network would fix the problem. Now (after upgrade to xubuntu 15.04 from xubuntu 14.10), the wireless light will shut off completely and refuse to come back on, even after: sudo modprobe -r iwl3945 (wait a few seconds) sudo modprobe iwl3945 Last time this happened I manage to dump some information, you'll find it attached. Package versions are the latest from vivid-updates and vivid-security. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1408963 Title: [Xbuntu 14.04, 14.10 and 15.04] Network manager stops working: iwl3945 0000:03:00.0: BSM uCode verification failed at addr ...; wlan0: deauthenticating from... by local choice (Reason: 3=DEAUTH_LEAVING), To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1408963/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
