I am having this exact same problem, but am using version 1.2.26ks of iwl3945 and version 1.3.27k of iwlcore. Most of the time, I can fix the problem by running:
rmmod iwl3945 rmmod iwlcore modprob eiwl3945 modprobe iwlcore though sometimes I need a full reboot. -- iwl3945 goes defunct, requires rmmod + modprobe https://bugs.launchpad.net/bugs/205506 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
