Does the C3700 work with Comcast, Spectrum and Cox?

Yes. It is CableLabs DOCSIS 3.0 certified and listed for major US cable providers including Xfinity, Spectrum and Cox. Check your provider's approved modem list before buying.

Is it fast enough for my cable plan?

It is rated to 340 Mbps down and 123 Mbps up with 8x4 channel bonding. That suits plans up to roughly 300 Mbps; faster tiers will be held back by the modem.

Can I use it as just a modem with my own router?

It is a modem and router combo, so it handles both jobs. You can put your own router behind it, but you would then deal with two Wi-Fi networks unless you disable the C3700's wireless.

How many devices can I connect by cable?

There are two gigabit Ethernet ports, so two wired devices directly. More wired devices need a separate switch.

Does it support voice service?

No. The C3700 has no telephone port, so it cannot carry a provider's voice line.
