just want to pitch in my experience..

I'm using wireless network for my gaming PC right now.. my connection is quite good so far, no lagging or jerkiness that is noticeable..

however.. this is after I changed my wireless network card to external USB wifi device and it even have an external antenna connected to it.. my previous wifi device gave me all sorts of connection problems

so the moral of the story is.. if u are using wifi, try to get the High Gain wireless device that have 6inch antenna attached to it.. now I can even get near full bar reception from my neighbor's house

not adding much.. except for recettear
