We have a satellite dish that includes the modem and router in the same device supplied by ViaSat. I've added an extender toward the back of the house so I can get a solid signal while in the shop which is in the garage. Recently my iPhone would indicate: No internet signal when using the router, it would however work anywhere in the house using the extender signal. I'm sitting now right beside the router and still it says no internet signal but will show a signal with the extension. When I unplug the extension, my phone does use the main router. Does anyone have any clues about what's going on?
