My wired backhaul is no longer working for two of the three satelite units. This started happening right after the most recent firmware update. I have tried multiple reboots and physically powering off and powering on the devices in different orders, however, the two satelite units turn red when connected via the WIRED backhaul. When the Cat6 cable is disconnected and the units rebooted, they work fine in wireless mode. Prior to the firmware update, everything had been working fine for a few months since I purchased this unit on Amazon

My main Deco a BE65 unti and is named "basement"  It is set up as a router, connected to the Internet with a static IP address.  It functions fine.

I have an "outside" unit (Deco X50-Outdoor) that is connected via wired backhaul and it continues to work okay - even when connected via wired backhaul.

The other two units are "living room" and "kitchen" and these are the other two BE65 units.  These are the units that have stopped functioning after the most recent firmware update when connected via wired backhaul.  They will function when connected via wireless backhaul.

When connected via wired backhaul, I am using all new Cat6 cables.  All satellite units are physically connected to the "basement" unit - there are no routers or switches.  The wired backhaul was functioning as expected since July (when I installed the system) so I can only guess that the firmware update has caused this issue.

Is there any solution other than downgradeing the firmware?

Thank you.
