I recently went wireless and installed an Airport Extreme card in my G5 and bought an Airport Express. I plugged in the antenna lead and noticed that there was some other wire right by the plug. Is that supposed to be used for something? My signal strength is usually at max and my download speeds seem to be OK. When I play World of Warcraft, however, the latency link is always red and everything is laggy. I bypassed the Airport and plugged my cable modem right into my G5 and downloads and web pages seemed faster and the link in WoW was a constant green. Is there some kind of known performance problem with the Airport Express? Before this, I always played wirelessly on my PC laptop with no problems via my M$ Wireless Base Station.
