Does the MG8702 work with my cable provider?

It is approved for Comcast Xfinity, Cox and Charter Spectrum. Check your provider's approved modem list before buying, since other cable companies may not support it.

Do I still need a separate router?

No. The MG8702 has a built-in AC3200 dual-band router, so one device handles both the modem and Wi-Fi. A separate router or mesh system may still give better coverage in a large home.

Is it worth it over a DOCSIS 3.0 modem?

DOCSIS 3.1 gives headroom for gigabit and multi-gig cable plans and handles congestion better. If your plan is well under a gigabit, a DOCSIS 3.0 modem can do the job.

Does it support Wi-Fi 6?

No. It uses AC3200 dual-band Wi-Fi, which is Wi-Fi 5. Wi-Fi 6 routers handle crowded networks better, but this one covers normal streaming and browsing.

What comes in the box?

The modem-router unit and an AC power adapter. You supply the coaxial cable and Ethernet cable for your devices.

Can I use my own router with it?

Yes. You can turn off its Wi-Fi and connect your own router to its Ethernet port, though most buyers use it as an all-in-one.

Our take on the Motorola MG8702 Cable Modem + Wi-Fi Router

The Motorola MG8702 is a two-in-one device: a DOCSIS 3.1 cable modem and an AC3200 dual-band Wi-Fi router in one box. It is approved for Comcast Xfinity, Cox and Charter Spectrum, and it replaces the modem rental many cable plans charge for. Its main draw is DOCSIS 3.1 headroom for gigabit-tier plans plus a built-in router, so it suits people who want one box instead of a modem and a separate router. Against modem-only units it adds Wi-Fi but gives up the flexibility of pairing a modem with a stronger mesh system; against DOCSIS 3.0 combos it adds multi-gig support and better congestion handling. Owners rate it around 4.1 out of 5, with most praise going to setup and stability and complaints about Wi-Fi range and heat.
