The mysterious case of the 82Mbps PPPoE upload

Hello there,

I have just migrated over from UTM and would love some help with a curious case of why my PPPoE connection refuses to upload faster than 82Mbps.

I have a 200mbps down and 200mbps up fibre optic connection.

The PPPoE interface and LAN interfaces have gigabit negotiated. QoS is ok. Download speeds exceed 200Mbps - but I cannot replicate on the upload.

The 82Mbps sounds very much like the expected rate if the cable was 100mbps - but no, the system confirms gigabit negotiated.

I have checked all the cables with a cable tester - all ok.

I plugged in my old mikrotik router, and it managed to get 180Mbps in both directions before topping out of CPU - so it is not my fibre connection.

Using dedicated quad core pentium 2.6Ghz with 8 GB of RAM - system is idling under load.

Can you help - is there something odd going on here?

Any tips on how I could test the upload speed and / or correct?

Thank you kindly.
