changed modem now limited radio connection

Hi I have changed the modem here in Australia to a new version, the radio servers time out and dont start sometimes. Early on they would work for 5 minutes then stop now they come up with the red error in the corner.It is connected via wifi 5ghz 396mbps so good connection. Playing music via the NAS is great still but not via radio, I havent deleted and reinstalled the radio plugins yet but will try that next. Does the Pi 3 need to have ports forwarded, if yes then what ports are needed opened?
