NetGear CM1000v2 modem and Spectrum provided Voice modem for 200Mbps Internet

[ptb666]

I am using NetGear CM1000v2 modem and Spectrum provided Voice modem.

Connected using a spliiter.

Why is speed only 75Mbps instead of 200Mbps ?

Probably because spectrum only allows 1 public ip address?

I'm surprised it works at all. 

What voice modem do you have?

I have to check on Voice modem model.

It is not at my current location.

I have thinking of testing the internet speed by just connecting from wall directly to the CM1000v2 without splitter to verify 200Mbps?

Which one?

reason I ask is again, spectrum only provisions clients for 1 public ip address. I'm impressed that device AND the cm1000 is working. If the spectrum device supports your speeds and you need voice, then just use the spectrum device. The issue is probably related to having to modems on your network.

Let me check later today when I have access to the location.
