So my brother have a problem with Internet on his computer. You know that Internet Indicator/Icon in the right hand side of the tray in Windows 7 which indicates LAN/WLAN status ? He can use computer as always but It either randomly stop working and suddenly displays yellow exclamation mark or when we try to download a game via Origin after like 5 - 20 minutes it's happening the same thing. The only way to do is to turn off and on Lan adapter in computer management. I want to also add while this is happening, other computers in the network have internet and router is working as it should.
Any suggestions ?
