I get this dialog a number of times each day for both my Mesh routers.

I have reported this to FING support and have never been able to work it out. Also, I get no network disconnect reports or outages. Below is a screenshot. Also my setup is as follows. Main Router connected to Xfinity Gigabit router. Wi-Fi is turned off on Xfinity router and the network is created by the ASUS AiMeash router. There is an additional ASUS router operating as the mesh Node.
