Hi, barging in on this thread…
We have the same problem here. SSID disappears after a few hours. Only a hard reset of the surf SOHO will bring it back.
And we are in a similar RV environment, we are in a TV production truck. With WiFi communications being an essential part of our operations.
We are considering adding an Airport base station to resolve this. We need it to be absolutely reliable.
I have tried the above settings but the problem keeps popping up.
And firmware is at 6.3.2 with Output power now dropped to medium with boost off.
…Food for thought :
A Truck or RV constitutes practically a Faraday cage. Could it be that the WiFi reception gets overloaded by reflexions and just cuts off and falls in a “self protect” mode ?
