My home came prewired with ports in each room. The cable going into the house didn't have a terminal piece, so I wired it with the rj45 connector and plugged it into my modem. Prior to wiring it, I checked the configuration in the bedroom and it was set to the t568A configuration, so that's how I wired it. I plugged my computer in to the bedroom wall and it worked great. However, none of the other rooms work. I've used the same cable and they don't work on my computer or my xbox. I pulled the jacks out of 2 of the walls, and they are also in the "A" configuration. Any ideas?
