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...

what wired speeds do you get? Not wireless.

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?

One final thing to rule out is the wiring of your Ethernet connection.

Some (old) Ethernet hardware is 100BASE-TX. If you have an ancient PC that can limit the speeds to 100 Mbps.

The C7000v2 is 1000BASE-T.

Older cables can also slow you down.

  Like michaelkenward says, check your wired device.
  The wired connection should provide the fastest connection and your 5ghz is actually hitting faster speeds.
  do you have a screen snip of the cable connections page? (shows upstream/downstream values)
  Post that back on here. I've had comcast say a line was fine when it wasn't.
  I've also seen them overload an area so have inconsistent speeds. Its part of why they're pushing to get people on docsis 3.1 modems.
