CM1100 - New gigablast user stuck at 300M instead of 1000

A few weeeks back I got a CM1100 Netgear Modem, and upgraded my cox service to gigblast

I have never seen the gigablast speed

The best I have achieved is 300MB speed

Im wondering if the cox side still thinks I have a docsis 3.0 instead of a 3.1?

Any ideas?

Can anyone who gets close to gigablast tell me what looks different on their modem status page?

Looking at the modem status screen I see this
