Hex PoE with Unifi AP fails to negotiate 1 GBps

Sat Nov 06, 2021 1:59 pm

Hi there,

I'm a bit at a loss with the following:
I have a Unifi AP (Mesh Pro) connected to a Hex POE router (with a 48V PSU). When the device is directly connected (power supplied by the Hex) both devices fail to negotiate 1 Gbps and fall back to 100 Mbit/s FD.

When I put the Unifi POE unit in between, 1 Gbit/s gets negotiated. Forcing 1 Gbits doesnt work.

I thought at first the cable was at fault but I even ran a cable test with it (with a separate testing device) which clears that. I have the same setup (Hex Poe 48Vbut with another model of Unifi AP) running without a problem and can't figure out what the problem might be.

Any ideas would be greately appreciated? Thank you!
