Gigablast download speed issue

Yeah if you want decent speeds your best bet is going to go buy a new cable modem you own.. When I got Gigablast upgrade the panoramic modem they supplied wouldn't give anymore then around the same speed you mention at the modem (speedcheck showed similar results when they had a tier 2 tech crew come out it was 900-950Mbps there were getting at the connection outside and they re ran the cabling to the house even and couldn't understand why they couldn't get more then 400-500 on their network analyzer at the modem) amazingly I went to Best Buy and bought my own Docsis 3.1 modem and suddenly yep sure as heck speeds went up significantly where my higher end router could speed check and even during busy times I was getting in the 800Mbps range and at night Id hit 900 or so..So the tech likely was full of it.. Go buy your own modem that listed as supporting gigablast (I agree we shouldn't have to because cox should supply hardware worth something to its customers but ya do whatcha gotta do sometimes).
