Yeah baby. Topic says it all. For the few months i've played bf2, my ping has spiked every 30 seconds to a minute from 30 ping up to around 800 then back down again with terrible consequences in game. eg. planes into carrier, helis upside down, jeeps into water and just generally being owned by my ping. But i just got a cable, ditched the wifi card in comp and no more spikes. Also, anyone who has ping troubles with wireless, I'd advise getting and cable and linking it up. This will make playing so much more enjoyable. Anyways, just wanted to express my joy.
I did that too Awesome.
