Well, I got my 360 back from repair and they gave me a refurb from April 2006. Well, that sucks. But, I am running into a problem. Before I sent it in, my internet connection on my Xbox was strong and had no problems. Now I cant stay on Live because I keep getting disconnected some how. I am using my Xbox Wireless USB Adapter. I am using a Linksys WRT300N (yes I know it is not on the list, but it works with no problems before). Anybody got any tips? I have opened all ports and assigned my 360 the IP 192.168.1.108.
