Hi, I've been having some trouble lately with the wifi on my Lenovo X201 and I was wondering if anyone was having similar trouble or could suggest a fix. All help gratefully appreciated.
I've been banging my head on google around this for a good number of weeks now and the suggestions that I've found (mostly around turning off IPv6) don't seem to resolve it. I've also tried resetting the bios to the defaults and re-installed Ubuntu 11.10 (the problems started in the summer under 11.04). The card is: Intel Corporation Centrino Advanced-N 6200 The error message from dmesg is: [ 52.966566] iwlagn 0000:02:00.0: Error sending REPLY_QOS_PARAM: time out after 500ms.
