R750 2.5G POE port limited to 55Mbps down, 94Mbps up

[Alleprt]

Running Unleashed. I have one R750 AP that produces such speeds on speed tests with power supplied through the 2.5G POE port. The speeds are quite consistent, maybe + or - 2Mbps. When I connect another R750 to this cable it produces normal speeds, close to 1Gbps down and up. POE at is manually selected in settings and the injector is definitely at, no problems with other APs. 

When I connect uplink to the other 1Gbps non-POE port and use a power adapter the speeds become normal, close to 1Gbps. So, something is limiting that POE port. I think it would be unusual if a hardware fault would limit speeds to such consistent values. Is it possible that something in the settings is limiting that particular port? I did factory reset several times without any change. That AP didn't have Unleashed initially and I cross-flashed Unleashed to it. I did the same to other 3 AP and they don't have any issues. Is it possible that some limiter was left over from another firmware and was not cleared by factory resets? Where can I look? I assume I need to use CLI.

Hi Allepet

Thank you for reaching out to us.

Based on the details you’ve provided, it appears that the issue is isolated to a single R750 access point, as swapping with another unit of the same model did not reproduce the problem.

To proceed with further investigation, I’d recommend logging a support case with us. We would be happy to assist with a deeper diagnostic and resolution.

Thank you
