Spectrum Gig CM1100
So I was told by multiple agents that I can use my own modern for spectrum gig. Splurged on the high install cost, got their (generic) modem, checked that the cm1100 is compatible on their networks, a...

I appreciate the quick response. After going round with Spectrum I sent the modem back for a replacement with Amazon. I'll PM you once I get the replacement. Thanks again!
Did you get this working? I am having a hard time getting spectrum to lock all of my channels. I feel like this is an issue with Spectrum, but want to know what, if anything worked for you?
Be sure you are using good quality RG6 coax cabling up to the modem.
Be sure there are no cable coax line splitters in between the modem and ISP service box.
Have the ISP come out and check the line...

I have a split. When troubleshooting this, I removed the spliter and used a different coaxe cable. The results were the same. I am not sure if it is a RG6 cable or what standard the coaxe I have is. I am getting the expected results on speed tests. Although, this is not what I am trying to improve. I want to reduce latency by leveraging the DOCSIS 3.1 and maxium bonded channels available to me. I think this is an issue with signaling from Spectrum, but also could be a firmware issue since Netgear states they issued Spectrum v3.1.6, but my modem is running v3.1.4. Spectrum refuses to acknowledge they push firmware updates to customer owned modems and is refusing to take much of any responsibility.
Of the 32x8 channel bonding I am only getting 24 down and 4 up.... On the DOCSIS 3.1 2x2 OFDM/OFDMA channeling, I am only getting 1 down. I also see a high number / percentage of correctable errors and fortunately, no uncorrectrable errors..... Spectrum has assured me that they support 32x8 and 2x2 OFDM/OFDMA channeling at my residential location. I have attached an image of the lack of channel signaling...
