I hope these lines may help. Another thing is, the back port modules doesn't fix the wifi problem for me but they cause another which is reported here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/286285/ I followed the suggestion in the thread above and removed the back port modules and the problem doesn't appear again. -- iwlagn causes kernel panic on 802.11n wifi https://bugs.launchpad.net/bugs/323622 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
