Ok, I'm getting a gaming PC and have one BIG problem. My router/modem is at one corner of the house and my computer is supposed to go in the other corner of the house. I am looking to play Battlefield 3, CS:GO, CoD:4, DayZ, and some other online games that require good connection to even do decent. I am going to be downloading different things and uploading videos to YouTube. I need a VERY FAST WiFi adapter that is comparable to wired connection, and remember, my computer will be all the way across the house.
