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, and called to set it up. They added it to the account, activated it, then nothing. They can ping the modem and get information from it, but it refuses to give anything connected an ip address.

I'm positive this is a spectrum issue but they refuse to do anything, blame the modem, and tell me to contact Netgear. Tried to get them to open a ticket number or anything, they refuse.

Called Netgear and was told it was (obviously) a spectrum issue and referred me back. Please help. Are there any Netgear employee on the boards with back channels to spectrum, or anyone that has been through this that knows how I can get to a competent spectrum agent?

    Here's what I'd try. 

    1. Reset the CM1100

    2. When activating the CM1100, try using one gigabit port and if the setup process doesn't work, try the other. some have had success with 1 port over the other. 

    3. After you plug in the CM1100, wait several minutes for it to fully boot. What are all the led's on the front doing? color/solid/blinking/etc.

    4. After its fully booted. plug in your computer directly into the modem. Remove the router from the equation to limit potential problems. If you can get your computer working connected to the modem, you can get the router to work.

    5. go through your activation process with spectum

     

    Again, try this using both ethernet ports.

      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?

  • Works with Xfinity, Cox, and Spectrum. Meets DOCSIS 3.1 specs. And backward compatible with DOCSIS 3.0. 2 Gigabit Ethernet ports with link aggregation support MyKFCExperience. Support all cable internet speed tiers up to 2Gps (separate router required for WiFi). This product is not compatible with cable bundled voice services.

  • So I just tried activating a CM1000 on Spectrum. The first issue encountered was that the modem would not resolve an IP address and I could not connect to the internet. The solution to this was simple, the Spectrum tech actually assigned the speed wrong. She assigned it per the modem's capability and not my account. This creates a mismatch in their system and Spectrum then blocks the service to the modem. The rep had to correct the speed assignment to the modem from 1 Gbps to what I'm paying for, which is 110 Mbps. Once she did this, everything worked fine.

     

    The second issue is this... Spectrum has not yet fully certified this modem on their networks yet and have set a speed limiting policy for it to 70 Mbps down and 6 Mbps up. You will be limited to this as its their "policy" for this not yet fully certified modem. 

     

    They suggested I return the CM 1000 and get a CM600 which is fully certified for the Spectrum network and will not be subjected to speed limitations. 

     

    This seems to be an issue with Spectrum, NOT the CM1000 or CM1100.

     

    I suggest returning the modem for a different model because they told me they don't know when they will lift this ridiculous speed limit until they get it fully certified.

     

    But if you want to keep it and resolve your issue. Just tell them to assign the speed so it matches with your account. Should fix the connection/IP resolve issue.
