I'm pretty frustrated. Purchased a CM1100 cable modem from Costco.com because it shows Charter/Spectrum compatible... yet when I went to activate it - they say it's NOT compatible. Escalated to multiple technicians... even had a very nice escalated support specialist call me back and spend time with me trying various methods to activate it, and it would not. Their modem works fine... my Arris modem works "fine" (I just typically prefer Netgear). Any advise on why they're unable to activate it or who to speak to about getting it activated? I feel that if it's advertised as compatible, it shouldn't be this difficult to activate it. Side note - I'm on their Ultra package and their system gives them an error saying "modem not compatible with speed tier" and will not allow them to proceed. Since it's only on their Minimally Qualified list - they pass it off as being a poor fit and recommended I return it. Seems silly for a Docsis 3.1 modem. Thanks.

If you guys have issue with Charter/spectrum: Please PM me the details (CM MAC, Account #, holder name, holders phone, summarize the issue). Please provide as much info as possible such as any open ticket# with spectrum, Spectrum chat log, etc. without above info it is hard for us to engage with spectrum engineering group.

vkdelta, i just bought this same modem from Costco. Would you be able to help me in getting this modem to be recognized on Spectrum’s system. I believe there are numerous other users out there having the same problem. Is there anyway that Netgear would reach out to Spectrum in resolving this. Thank you very much for your help

Ultra is just 400 Mbps speed. CM1100 should definitely work with it. Do you have spectrum ticket#?

I don’t. I escalated it through the call centers and through their social media as well. That’s when I got the callback. Would a trouble ticket help in this case? I can always try to get one. It seems other Spectrum users are experiencing the same issue based on other convos I’ve had. I’d be more than happy to escalate and get a trouble ticket if it would help.

Please get a trouble ticket. We will send it our spectrum contacts.

Has anyone else had luck with activating the CM1100 on spectrum? I have done some research and seen that people have had success but most of the success was because they reached out to Netgear. That seems silly because obviously it works so why give everyone the run around?

  I would like to know if I have this modem. I still need help from Netgear rep to reach out to Sprectrum to activate it?

    No, you need to contact your ISP and talk to someone there to activate it. You need to make sure they support it first.
