I've moved to a new house and try as I may my wifi connection from my IMac G5 to TimeCapsule (n) network is very poor. I did get a Buffalo g router the past week and flashed it with DD-WRT but still not good. My Mac laptop connect to TimeCapsule in N mode (not 5 ghz) and does great. So I was wondering if anyone knew of a USB 802.11n network adapter for my IMac?
