Speed bump from 1Gbps to 1.2Gbps not working

I got the notice of increase, but only get about 940mb with 23mb up. 

I have a Net Gear CM2000 MODEM connect to Asus AX-89X router in 10gb wan, and using 10gb out for lan to my pc which has tp link TX401 10GB card.

I do have a tech coming Friday to test the line, but is there anything else I should try?

1. I have reboot modem and factory reset router already. tried directly to the modem same speed.
