Yarbo WiFi settings

Yarbo WiFi settings

I have UniFi as my outdoor WiFi. It’s a mesh system. My yarbo base has connected just fine to my UniFi system. I can’t however seem to get the rover to connect and stay connected. What are the optimal WiFi settings to keep Yarbo connected? I have tried both using my phone and the Yarbo tool. I can get it connected to my WiFi from inside the house but it won’t seem to connect to my outside access point. 

Does Yarbo have an optimal channel, channel width 2.4 or 5ghz,  or any of the other settings?
