Not Getting Gigablast Speeds

I recently upgraded my service and I am only getting 300-600 mbps and I am averaging around 400 mbps. I have a CM1100 DOCIS 3.1 modem. I have had multiple tech's out to fix issues on their end (terminations are curb and amplifier in node) and I have only seen a small improvement from what I was getting prior to the fixes, 200-500 mbps. Here my modem connection stats are below. Anyone have any ideas?
