I bought a 2020 Coachman Prism 2200FS and have the same problem. The dealer didn’t have a clue what the switch was for. I don’t see the WifiRanger network when I turn it on. Any advice would be greatly appreciated. Hello, did you ever get your WiFiRanger working on your Prism? I have spent way too many hours on this and seem to be getting nowhere. The blue switch goes on, but I do not see the WifiRanger Network in my available networks. Thanks.
