Christopher, no, I can't upgrade the BIOS; my wifi card its not Lenovo branded, and I had to hack the whitelist in the BIOS to use the card at all. In any case, this is an issue with the wifi card itself, so unrelated to the system BIOS.
But the problem has not recurred with more recent kernel releases, so closing as resolved. ** Changed in: linux (Ubuntu) Status: Incomplete => Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1036427 Title: 8086:422b [Lenovo ThinkPad ThinkPad X201] unreliability with Centrino Ultimate-N 6300 wireless connection, 802.11n To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1036427/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
