I'm having some issue with internet access. I've got a Samsung laptop with a Broadcom wireless card and Ubuntu 12.04 on it. Everything worked fine at the beginning, but recently, probably after some kernel update, I noticed that I don't receive any packets for few seconds. When I tried to look what's wrong I noticed I can't access to router (some cheap TP Link), even ping is failing. Router is ok, because I am able to access it from other devices, and even from my laptop from Windows. But this disconnecting is very annoying. Anyone has the same issue? Where can be the problem?
