(Yet another) SB8200 and Gigabit Speed call for help

Hi - trying to figure out why I'm topping out at 150-300 Mbps here in DC. We were on a 600 Mbps speed tier but always seemed to top out at 300 or so at the most. SB8200 Config info is below. Updated home infrastructure to Cat.6 but for the sake of troubleshooting am running speedtests while hardwired direct to LAN 1 on the modem.

 

Any ideas? Thanks in advance!

What do you get for the upload speed ?

A steady 40 Mbps upstream.

This morning, ever since submitting the order for gigabit last night, the downstream has now topped off at 150-180 Mbps.

Have you tried rebooting the SB8200?

O/k so then it appears to be provisioned correctly for the gigabit speed tier so that's not the issue.

Rebooted the modem plenty of times, called T1 support and she ran diagnostics on the line levels and said everything checked out.
