Is new Modem (C2000) compatible with my AC1750 Router

I have a docsis 3.0 netgear Gateway and am an Xfinity streaming customer. I’ve had nothing but issues for the past six months and Xfinity says it’s not their problem but I refuse to rent from them and...

Thanks for catching that.. I’m thinking of purchasing the CM2000 (modem) only. Today I have a combo modem/router. I also have a spare R6700 router not being used that I would use with the new CM2000.

Again, any thoughts or recommendations are welcomed.

What actual modem are you currently testing with? 

How are you speed testing? (device, website, etc)

What actual router are you using currently

    Currently using a combo modem/router.. netgear model C7000v2. I test the speed using Speedtest app and also the Xfininty app has a test. Just ran a test using both and below are results:
    Speedtest- download 41.4/upload 23.2
    Xfinity- download 57.7/ upload 23.2
    NOTE: I’m sitting 6 inches from the gateway and only using one smartphone abs one PC.
    I have Xfinity extreme which should stream up to 400 Mbps.

        For comparison purposes I ran them both wired and non-wired witchin a close time internal:

        Using Speedtest app
        Wired: 90.26 Mbps
        Wireless 2.4 channel: 93.9
        Wireless 5G channel: 204

        Using Xfinity speed test
        Wired: 123.3 Mbps
        Wireless 2.4 channel: 92.2
        Wireless 5G channel: 190

        All along I’ve thought the issue was Xfinity and they made it sound like it was my Gateway...Now that I see these numbers sounds like it is an Xfinity issue. Would you agree? Also, why is the top end speed nowhere close to the 400Mbps they advertise?

      That is as fast as you will get with some wifi clients. It won't get any better with new hardware.

       

      Wifi speeds tells you nothing about the quality of your internet service.

       

      As plemans says, the only way to test that is with a wired connection.
