The following workaround has solved my issue on my ThinkPad X220 with Intel Centrino Wireless-N 1000 card using iwlwifi driver (except, of course, that I don't have N wireless capabilities now): 1) Create a file at /etc/modprobe.d/intel_11n_disable.conf containing this one line: options iwlwifi 11n_disable=1 2) Run this command: sudo update-initramfs -u 3) Reboot -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/939218 Title: Intel Centrino Wireless N-1000 WiFi slow and disconnects sometimes (iwlwifi) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/939218/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
