So I just got a PCE-AC56, and the speed is fine on speedtest and pingtest, but the second I try to game online with it i get insane 300+ ping, totally unplayable and this should not be the case. (I thought it would be worse than wired but not THAT bad). Any idea what could be causing this and any ideas how to fix it. (also the card is plugged into my second PCI-e x16 slot, not the PCI-e x1 slot since that didnt work at all).
