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...
Yeah I am not sure what to do. I am hoping they send me the DOCSIS 3.1 modem, but won't know until next week. If they don't, I am likely going to return the CM1000 and purchase the CM700 since the CM700 is listed as Approved for Spectrum internet < 400Mbps. The CM1000 is only "Minimally Qualified Modem".... I posted the link to the modems they approve and provide. The MB8600 and the SB8200 are minimally qualified as well. There is not a single modem a customer can buy that is approved by Spectrum and that supports DOCSIS 3.1. What a joke....

I strongly believe this is a signaling issue on Spectrums end. My CM1000 is 32x8 channel bonding, but it is only using 24x4. I am hoping that the new modem they ship me is at least 32x8 even if it doesn't support DOCSIS 3.1. Atleast then, if the signaling isn't getting the 32x8 on their hardware, it is clear that the problem is on their end and not the CM1000. My other thought is, purchasing the CM700 (since it is approved) and trying to get all 32x8 channels. This could be difficult since Spectrum is quick to not support customer owned hardware.... even if it is on their authorized modems site...
Additionally in an attempt to resolve the signaling issue, I took my modem into my basement where the coax comes in from outside and plugged my modem in directly there. Same results. Tried a number of different RG6 coax that I had laying around and made no difference. I ordered some new high end coax cables and a coax connecter the supports 3 GHz. I doubt this will make a difference, but at this point, I am not leaving anything out!
