Sometimes it connects to router but internet is like 20 kbps, speed test: http://www.speedtest.net/result/2746428758.png . More times it says that: windows was unable to connect Edimax(router).
Troubleshooting says that problem is with WI-FI adapter or access point.
I tried:
Power saving options
Windows repair and reinstalling
Transmit power to High
Newest WI-FI updates(Bios update included)

Recently I disassembled my laptop to clean from dust. Also changed termo pasta for cores. Can this effect wifi? p.s. while assembling pc all wires were connected correctly. Do I need re-assemble it again to check it out?
So what solutions u can give me? Any Idea?
