RBK 853 5gHz Wireless Backhaul Issues
About 30 days ago, my otherwise rock-solid Orbi 850 system (RBR + 2 RBS) began to slow way down. After some troubleshooting, I noticed the backhaul was using 2.4 gHz, not the dedicated 5 gHz band and...

Refurbished RBR850 arrived yesterday. Initialized it and replaced my old RBR with refurb about 1 hour ago. Used backup config file to set up refurb and re-synced sats. After about 10-15 minutes settling time the system came back to daisy-chain topology. 5 gHz backhaul (see screenshot) is working and speeds throughout property are back to historical numbers. (Over 3X faster than when 5 ghz backhaul stopped working).
Obviously, my original RBR had some sort of tx/rx problem in 5 gHz band. All is good...for now!

Since you have already done a Factory Reset and have temporarily moved one satellite into the same room as the router, this does not look good.
It might be time to consider connecting at least one of the satellites with Ethernet cable. The cable itself is not expensive. In many houses, the effort to install cable is overwhelming. (why my satellites remain connected using WiFi backhaul.)

Agreed the effort required to install Cat 6 cable to my RBSs makes it a non-starter. I've ordered a refurbed RBR from Amazon.com. Will test that and report back.
