Hello. Just purchased a 3-pack of BE85's. Using wired backhaul over CAT6. Testing with iperf3 to my Synology FlashStation which is connected to the main BE85 via 10GB SFP. Satellites are directly wired to main deco - no switch.

1.6Gb/s throughput at close range via wifi6e to the main BE85.

1.6Gb/s throughput at close range via wifi6e to a satellite deco -only if- satellites all use the 10Gb ports for backhaul.

1.2Gb/s or lower throughout at close range via wifi6e to a satellite deco when the satellites are using the 2.5Gb ports for backhaul.

This is repeatable 100% of the time. Been futzing with it all day. I can sit beside a satellite deco and switch the cable from the 2.5Gb port to the 10Gb port and throughput matches the primary deco. Back to the 2.5Gb port, satellite throughput back down to 1.2Gb/s.

I want my 10Gb ports for my ATT modem and NAS. Ideas? Are the backhaul ports half-duplex?
