Yet prior to this only my computer was working through the router as the other had some tech issues and I was fine playing online with others. What could be the issue here and is it possible to fix?
I can host a game no problem However when I give my ip to people from "showip.com" they cant get into the room however this was possible before my brothers computer got connected to the router again.
The router we got now is called "Buffalo Air Station, TURBO G"
