Bug Description
I have a Lenovo Thinkpad T60 with Atheros AR5212 wi-fi adapter. When it is connected by wifi, it loose packets exactly every 2 minutes (120 seconds). Packet loss is about 2-4%. When I connect ethernet, no packets are lost. Another laptop (dell) in same wifi network do not loose packets as well.
Problem affects skype, every 2 minutes remote person can not hear me for a few seconds, while I hear him perfectly.
Attaching a log pinging my local router.

Hi Alexander,
If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https:/ /wiki.ubuntu. com/KernelMainl ineBuilds . Once you've tested the upstream kernel, please remove the 'needs- upstream- testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs- upstream- testing' text. Please let us know your results.
Thanks in advance.
