I upgraded to the latest stable release of the 3.0.x series kernel, 3.0.10. For testing I removed the line "options wlagn 11n_disable=1" from options.conf in /etc/modprobe.d/ and reboot into the new kernel. This problem still persists in the latest 3.0.x series kernel. I re- added the options for the wlagn driver in options.conf and reboot back into the 3.0.10 kernel, and connectivity went back to normal.
Connection is stable on the 3.0.x series kernel with 11n_disable=1 and stays stable. However, with the 3.1.x series kernel with 11n_disable=1, the connection is stable for only a few minutes at a time, which then it drops the connection all together. Either series kernel without 11n_disable=1 results in a completely unstable and unusable wireless connection. -- 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/ubuntu/+source/linux/+bug/836250/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
