I'll get straight to the point. I just built a gaming rig, and I have no choice but to use wireless due to the fact that the modem and router cannot be moved from the main floor of the house. My PC is down in the cave and I get horrible connection. I'm using TP-LINK model TL-WN851ND. Would buying a better/bigger antennae do me any good, rather than using the antennae that came with it? Any suggestions?
