Orbi RBK50 Losing “internet connection” with wired backhaul

Thanks I will give disabling the daisychain a try. I have just been using it without wired backhaul for now. When I intially set up the router I used the iOS mobile app and again after the last time this issue happened. I don't remember setting an router password and the default admin/password combination isn't working.  The password recovery feature seems to be active but my answers to the questions are not correct.  Mainly because one of the questions is "What is your youngest sister's name?" and I do not have a sister.  Do you have a suggestions on how access the settings another way?

I do have a couple of switches in the mix.  I have an Araknis AN-100-SW-R-S that splits into a Microprice 12 port cat 5e patch panel that goes to various hubs in wall ports in home two of which I used for wired backhaul. The other connection from the Araknis goes to a Netgear GS608 network switch that supplies a bunch of AV equipment (satellite TV box, Bluray player, Apple TV, sonos bridges, etc).

Thanks again for the reply.
