Hello, We had a new system installed yesterday. 1 Hopper, 2 Joeys, 1 Sling. Everything seemed fine except we were having internet connection issues with speed and connectivity after the install. After a couple of support calls to Dish and our ISP, we now know it is a problem with the Hopper in the network. We now have the Hopper disconnected from the ethernet cable and the internet is back to running normal. With the Hopper connected, it switches on/off constantly with it being mostly off. This can be seen on the network set up screen as it refreshes it says connected then not connected. This was ongoing for almost 20 hours until we disconnected the Hopper from the network. I've looked around in the set up, but cannot see how to make any changes. A call to Dish support seemed to be little help as they only want to send a tech out. I don't think there is any problem other than the settings. I already tried changing ethernet cables and connection ports. I also have done multiple hard resets on the router and Hopper. This was an existing ethernet connection that was changed over from Direct TV DVR to the Hopper. No problems before the Hopper. Any help is appreciated. Router is a 2012 Apple AirPortExtreme. ISP is NextGen Access sent via a repeater to an antenna on our house. It all works great without the Hopper.
