Public bug reported:
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.
