could any of you disconnect your router and directly connect your xbox one to your cable modem with ethernet? that would tell you that its your router. could be a NAT problem. there is 3 types: Open, Moderate, closed. ps4, xbox one, PC, doesnt matter, it could be ports that need to be open on your router. there are tutorials/videos on how to do so. i cant getin my brothers game!!! (both if us are on xbox one)
