Searching around I found the following thread which seems to be related: http://thread.gmane.org/gmane.linux.kernel.wireless.general/29172
That thread noted the following which seemed to have positive feedback. "This sounds like http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=1703 for which new uCode was released to address the problem. Could you please try with the most recent 4965 uCode available from http://www.intellinuxwireless.org/?n=Downloads ?" It would be good to know if this resolves what you are seeing. I'd note that Karmic already has this newer firmware available if you were to test. Thanks. ** Bug watch added: Intel Wireless Linux Bugzilla #1703 http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=1703 -- iwlagn/iwlcore modules stop responding https://bugs.launchpad.net/bugs/378189 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
