I am connected to the new BT Hub 4 by ethernet cable. I am sued to streaming video from my laptops to my Xbox. For some reason the Xbox is not recognising my laptops. The settings on the hub tell me all are connected to the Hub 4 but they don't appear in the PC connection section on the Xbox. I had no problems with the Hub 3 and the laptops automaitcally popped up in the Video streaming section on the Xbox but this Hub 4 is causing me problems. I tried opening the ports on the laptops suggested by the Xbox help section, which worked temporarily but when I turn the Xbox off and try it again the laptop has gone. It seems the ports are closing when the laptop is turned off.
