M350 but only getting about 110mbps max

I've checked all the cables, restarted and reset the hub, tested on different devices, in Windows safe mode and on Android, wired and wireless.

Re: M350 but only getting about 110mbps max

Your downstream power levels are out of spec (-6 to +10 is in spec).

You require an engineer visit to either adjust the power levels at the cabinet or fit something like this between the HUB and cable to the wall socket:
