RBE971 reboots

RMAd router did reboot unexpectedly once since install... however the symptoms were slightly different.

Post repalcement of the router, I've had stabiliyt issues with satellites.   

The Satellites have been powered down.  I'm just running the whole house with the router alone - and THAT has been pretty stable.   

Will probably give it another few days/week and see about adding one satellite to see if I can get a 1+1 configuration stable....

When I was having satellite trouble, the status light would regularly just flash white - like it was booting.  But the web interface on the router seemed to show the satellite still connected...   with no clients.   Assuming some lag in status when the satellite reboots.

But when a satellite got like this, it kept flashing white... never did finish what I thought was the boot cycle.   

That's why they are both off currently.  I'll do a factory reset on one and try to bring back on line probably over the coming weekend.

Ok, keep us posted on the RBS.

What is the size of your home? Sq Ft?
What is the distance between the router 📡 and satellite(s)🛰️? 30 feet or more is recommended in between RBR 📡 and RBS 🛰️ to begin with depending upon building materials when wired or wirelessly connected.

What channel configurations are currently set on the router?

You might reset the entire system while both RBS are connected and let the system fully come to ready and get any FW updates on the RBS as well, if needed. I would do this with the RBS near the RBR or same room, say 15 feet away. 
You can follow this PDF Guide to run thru the reset process.
