Thank you all for your replies. Our home base is Crystal River, Florida since 2018 and originally from PA. We are waiting on Tech Service to come back and recheck system since we had it checked at Cummins. We will keep you posted on what they find this time. We do have a large surge protector on our 50amp main line, but believe the strike came in thru internet line at post. We and a lot of other people lost routers, some also lost TV's/Computers. Does anyone know of a surge protector for internet lines?
