I have a home Sonos network with many Sonos products running on my home Wifi. I have a camper with a SoHo router installed. The idea is to take my cell hotspot or campground WiFi as as the WAN connection creating a local LAN in the camper. This all works as it should except for Sonos. It seems that only one of my Roams work and I can't create the stereo pair. The 2 Roams work as a stereo pair in the house but not in the camper. Any ideas.
