Today I installed this card in my PC, it worked fine at first, then I noticed it only connected to my network at the 802.11g standard and won't go any higher than 54Mbps.
So I went to Device Manager, went to the card advanced settings and changed them. OK, now it connects to 802.11n standard, but I can't play games on Steam. The connection to the Steam servers is lost, about 10 seconds after launching a game. Reverting the settings back to default, Steam games work but I have to play at a crappy speed of 54Mbps at 802.11g standard.
Please tell me how to force the card to connect at 802.11n standard without messing with the settings in the advanced tab.
