Netgear CM3000 issues. Hoping somebody can help.

Firstly, I have read thru several posts here regarding CM3000 and am aware of the issues and their possible solutions. I have a very similar situation to a user that was upgrading from a CM1100 to a CM3000 except that I don't have any line issues in the ground. My main issue is that coming off of the modem I was getting anywhere between 300-600Mbps and with my router (Asus RT-AC88U) my wifi speeds are at around 300-400Mbps. I've spoken with several tech support agents and they've all "provisioned" my modem and confirmed everything was good. They sent out a technician today that confirmed everything was good up to the modem (he was getting 2Gbps+ from the jack on the wall). I asked if he could check the speed coming off of the modem and he confirmed ~1000Mbps which he questioned seemed low because my plan is at 2Gbps and the modem is rated for 2.5Gbps. I mentioned about some of the known issues with the CM3000 firmware, but he couldn't do anything about that. 

My CM3000 is currently on v6.01.04 and when I login, via browser, it says my Connection Status: POOR and the downstream status is yellow. I will attach the event log. Could someone please help? Is there anything else I need to do? Do I have a bad modem?

Small update. The technician had mentioned something about my downstream power being too high and I also chatted with Netgear support who confirmed also my downstream was too high. I managed to get an attenuator and now am getting all green for downstream and upstream thru the netgear gui. I'm still only getting ~500Mbps from the modem. Any help?

Thanks for posting on our Community Forums for assistance, phyko1. Are you hardwired to the modem or testing the wireless connection through your router? Are your devices capable of reaching 2 GB of speed?
