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 Maybe others with the iwlwifi driver should try doing this. Notice how it's the same fix others have mentioned with the iwlagn driver, except that "iwlagn" was replaced by "iwlwifi" in the config file. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/836250 Title: [Oneiric] [Regression] Intel Corporation Centrino Ultimate-N 6300 poor networking, packet loss and very slow Lenovo X201 and T500 laptops To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/836250/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
