new Arris sb8200 - issues with downstream (no blue light) with gigablast

Hi There,

Wondering if you can help me, I just got an Arris SB8200 modem today and ordered Gigablast service. 

My lights are all green (no blue at all). I am in orange county, california (92630). I connect to Cox orange county server

and my download speeds range from 300-600Mbps. Upstream is consistent at 35-40Mbps.

WIFI speed is not consistent on downstream (100-250Mbps)

So I'm not getting advertised 940Mbps and the blue light (which Arris documentation states indicates high speed DOCSIS 3.1

connection is NOT ON - still green.

My older Docsis 3.0 modem and 200Mbps service didn't have this problem. Always consistent downstream for both LAN and WIFI.

Any ideas on what the problem could be?

Thanks,

Steve
