Two networks available in windows network and sharing centre, Network 2 (home network) Internet access homegroup joined and Unidentified network (public network) no network access and both are on separate connections. I've tried joining them but no change in the receiver network status, even assigning an ip to the receiver in the network settings thats within the range specified by the mobile router options via the browser on the computer. I know there are several issues highlighted here but the missing HD channels on hotbird is crucial i can live without net connectivity via the receiver but it would be nice, thanks in advance

Btw the cable traffic light indicators between the receiver and PC are flashing orange is on and yellow flashing (Pc end) and one green light and one yellow flashing periodically (receiver end).
