slow down speed on Gigabit connection

Hey guys, figured I'd tap into the knowledge pool here before trying 2 Degrees help-desk.

I just got a new 2 Degrees Gigabit connection activated yesterday, but I'm only getting 93Mbps down, 530Mbps up via the 2degrees ChCh server on Speedtest. Similar results on a bunch of other servers I tried.

Getting identical results on the Speedtest app via 5G on my S7 (93/525 on last test)

Fritzbox 7490 shows my current active connections as:

LAN 2 at 1 Gbit/s <-- PC Ethernet connection

WirelessLAN 5 GHz, 780 / 866 Mbit/s <-- Galaxy S7

My PC and phone are the only devices connected.

Power Mode is 1 Gbit/s on all LAN ports.

Enable ONT connected LAN 1 to Fritz LAN 1. Lights green (correct for Enable).

Anyone had the same issue? Only similar result I can find points to a NIC driver issue but I'm getting exactly the same speeds on the 5G connection to my phone.
