Welcome to the forums, I am sorry to see you have had trouble with your modem.
I am not 100% sure what is happening here can you explain a little further for me.
Are you finding the Superhub restarts when you connect a satellite receiver?
If so does the Hub restart at any other times or only when the receiver is connected?
What type of receiver is it, if that is the issue you have been having?
The connection looks ok from this side so it may be worth trying Getting the best Wireless Network Signal.
Let us know how you are getting on.
