Do I need a separate router?

Yes. This is a modem only. It has no Wi-Fi, so you connect your own router or mesh system to its Ethernet port.

Which cable providers support it?

It works with most major US cable providers, including Comcast Xfinity, Cox and Spectrum. Check your provider's approved modem list before buying.

No. It has no phone jack, so it cannot run a landline or VoIP service through your provider.

If you keep cable internet for a while, buying your own modem avoids monthly rental fees and gives you a modem that supports fast DOCSIS 3.1 tiers.

It has one Ethernet port, so it connects to one router. The number of devices depends on your router, not the modem.

No. It is a cable modem and only works on cable internet lines.
