RBR40 Orbi wired devices not connecting suddenly

What is the Mfr and model# of the ISP modem the NG router is connected too?

What is the Mfr and model# of the ethernet switch in the configuration.

After 18 months my RBR40 wired devices are no longer working - One port goes to switch to rest of the house.

ISP thought it was the cable modem so I replaced (ARRIS Surfboard - Compatible with Suddenlink).

Firmware is updated ( V2.3.2.58) - Rebooted several times (2 satellites not updated and working correctly)

No other updates - which wouldn't have been updated if the problem didn't exist first

Wireless devices are working correctly - 20+ devices

Connected multiple devices using multiple ports/cables 

Checked Access Control - set to "Allow all new devices to connect"

Auto DHCP - printer has a static address

Nothing else fancy - no port forwarding - just for home use

Any ideas as to why this would happen all of a sudden?
