RBR750 Mesh network

[George56]

I have an RBR750 mesh network with 2 satellites. They have worked well for over a year. The router is in my basement, one satellite is one flight up on the main level and the 2nd satellite is 2 stories up on the top level of the house. All of a sudden the satellites are no longer communicating with the router. They are flashing white and pink and sometimes blue. I have brought both of them into the same room with the router and reset them and attempted to sync them. In the same room all lights go out but when I put them in the other rooms - no success!

I would appreciate any advice to help get them back on line. I have no issues with the router.

Thanks.

Thanks Alex. I am not very technical. What specifically do you mean by power cycling?

Ignore the poster above. He's got spam links in the profile. 

1. what firmware is on the router and satellites?

2. what modem/gateway are they connected to

3. how big is the home? 

4. what are the walls/floors made of? (certain materials block wifi better than others)

5. They've never had syncing issues before?
