CM1100 Cable Modem NOT Charter/Spectrum Compatible

[J5150]

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.

Ultra is just 400 Mbps speed. CM1100 should definitely work with it. 

Do you have spectrum ticket#? 

[J5150]

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.

[vkdelta]

Please get a trouble ticket. 

We will send it our spectrum contacts. 

[J5150]

Sorry it took a couple of days to reply.  I attempted to have the open a trouble ticket and simply got a reply of "this modem is not certified for that speed tier and there's no trouble ticket to open for an uncertified modem."  I attempted to escalate and say that you all are wanting the info, but just got met with continuous refusal.

Hi, I am exactly in the same boat as you (CM1100+GoogleWIFI+Spectrum). Wanted to see if you had any luck resolving this issue before I freshly starting a simillar post. Thanks.

[J5150]

Yes I did!  PM the Netgear associate who was replying in the thread.  Reference this thread and he will assist.  Basically - he had to reach out to Spectrum directly to help with activation.  Something on the Spectrum end wasn't set correctly.

Looking to go with the nighthawk CM1100.   would like to know what the solutions were with this on Charter/Spectrum.

prior to ordering this modem, i like the idea of the 2 lan ports and thinking with this can split house into 2 subnets.

   I'd ask my ISP what (if anything) I'd be able to do with that second
port.

   Why would two subnets be better than one for your usage?

[simmsbru]

The purpose of using 2 subnets is to have one for the house and the family and the 2nd one for my office items as i do my jobs from home and tlike things split totaly apart and thought this might fit vs say hanging a Ubiqyiti edge router after modem to split things.

[vkdelta]

2 Ports WILL ONLY WORK FOR different IP, if your ISP supports multi-IP service.

Comcast supports it partially for residential and for Business customers. 

If your ISP does not support MULTI-IP services, you can use only LAG for 2 ports.

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?

[Mm530]

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?

[FURRYe38]

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

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

Please PM me the details (CM MAC, Account #, holder name, holders phone, summarize the issue) . I will help to fix it with Spectrum operations team.

I am looking into buying this modem and spectrum keeps trying to tell me this modem to be under their minimally qualified modems. Has anyone that has actually gotten it activated had any problems, good experiences? And also what do I need to actually get this thing activated as spectrum just doesnt want to do it? Also I've been told you cannot use your own modem on gigabit service with them?

[Anzi_2019]

I am super frustrated now, I still have the issue. @vkdelta , should I call Spectrum customer service?

[FURRYe38]

Were you able to get the modem connected to the ISP?

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.
