I have recently upgraded to the COX Gigablast plan. I have a brand new Netgear CM1100 modem. My upload speeds are great (36Mpbs), but my download speeds average 450mbps. I noticed that my modem is connected to 32 channels at QAM256. Should gigablast be using DOCSIS 3.1 and QAM4096??
I have tried modem reboots and factory resets. Nothing seems to get the speeds up. The modem is connected directly to the main cable drop, no splitters.
Any help would be great. Thank you in advance.
