    1. what are you testing those speeds on? (device)

    2. are you testing wired? wireless? 

    3. what website/app are you testing on?

    4. do you have a screen snip of the cable connections page and the event logs?

    5. since the speed increase, have you tried a factory reset and reinstall of the c7000?

      1. what are you testing those speeds on? (device) - windows lenovo laptop/mac os/iphone

      2. are you testing wired? wireless? both wireless and wired directly to c7000

      3. what website/app are you testing on? speedtest xfinity, google speed test

      4. do you have a screen snip of the cable connections page and the event logs? 

      5. since the speed increase, have you tried a factory reset and reinstall of the c7000? the device was already factory reset out of box

        Wireless isn't going to hit than those speeds on that device. 

        wired should depending on if you're device is capable of it. 

        make sure access control, qos, traffic monitoring, and parental controls are disabled and reboot the device

  • Don't just look at your modem/router for speed issues even if you upgrade.  You need to check the your network module's or network chip set on your motherboard for its speed limitation.  The bottle neck will reside with your network card/chip capabilitites.  If you can only go 100 Mbps then that's what you'll get.  If you absolutely know what your network card/module is capable of and your not getting the ISP provided speed along with your Router/Modem or combined Modem/Router's device, then look for the Router/Modem's speed limitation in it's documentation and also on the original box it came in for speed values you should be able to attain.
