Issues with Gigablast

Question

I recently upgraded from the Ultimate Internet packet to Gigablast.&nbsp; I purchased an Arris SB8200 and the DOCSIS 3.1 is not working.&nbsp; It's failing back to DOCSIS 3.0 and giving me the ultimate speeds.&nbsp; I check the event logs and finding the below failures.&nbsp; Any help would be greatly appreciated.

Internet is operational, but only getting around 300 mbs.&nbsp; I called support and they have reset my modem a couple times, still no joy.&nbsp; They want to send a tech out but curious if this is a provisioning issue that can be solved without a tech coming out. Here is my current modem status;
