Can't access Spark fibre with TP Link AC750

Switched to Spark today and no internet. Why am I not surprised.

I've gone through the help page: https://www.spark.co.nz/help/internet/set-up/non-spark-modem/

And changed what I can see, but can't find options like

Operating mode: MDI/MDIX

Encapsulation: 802.1Q

PCP marking: 0

VID (or VLAN): 10

I've changed what I can but internet is still not working and Spark say not our problem contact tp link.

Any help on offer?
