- Best overall: Motorola MG8702 DOCSIS 3.1 Cable Modem and AC3200 Wi-Fi 5 Router
- Best budget: Motorola MB7621 DOCSIS 3.0 Cable Modem
- Best premium: ARRIS SURFboard S33 DOCSIS 3.1 Cable Modem
- Best for a separate router: Motorola MB8611 DOCSIS 3.1 Cable Modem
- Motorola MB8611 is a modem-only choice with a 2.5GbE port for shoppers who already own a router.
- Motorola MG8702 combines a DOCSIS 3.1 modem and AC3200 Wi-Fi 5 router in one device.
- Motorola MB8611 and Motorola MG8702 both require cable internet service and provider compatibility checks.
- ARRIS SURFboard S33 offers DOCSIS 3.1 with both 2.5GbE and 1GbE Ethernet ports.
- NETGEAR Nighthawk CAX30 adds Wi-Fi 6 to a DOCSIS 3.1 modem-router combination.
Motorola MB8611 is the better fit for shoppers who own a router, while Motorola MG8702 is the simpler all-in-one pick with a built-in AC3200 Wi-Fi 5 router. Both combine a DOCSIS 3.1 cable modem with support for faster cable internet plans, but their key difference is whether you need a separate wireless router.
For this Black Friday 2026 guide, I researched and compared specs, reviews and owner feedback across seven cable modem and modem-router options. The right pick depends on your internet provider, speed tier, home layout and existing network gear—not just the model name. Check your provider’s approved-device list before you buy, and remember that none of these products replaces a modem for fiber or DSL service.
How We Picked
- Compared DOCSIS standards and Ethernet port speeds to identify devices suited to current cable plans.
- Separated modem-only models from modem-router combinations so shoppers can match the product to their home network.
- Reviewed Wi-Fi generation, rated wireless class and wired ports for everyday device support.
- Considered provider compatibility as a must-check, since approval varies by internet company and plan.
- Used researched specs, reviews and owner feedback to weigh setup convenience, upgrade flexibility and practical limitations.

Motorola MB8611 vs Motorola MG8702: which is better?
Motorola MB8611 and Motorola MG8702 are both DOCSIS 3.1 cable devices, but Motorola MB8611 is a modem-only model and Motorola MG8702 adds an AC3200 Wi-Fi 5 router. That distinction makes the router question the fastest way to choose between them.
Pick Motorola MB8611 if you already have a router you like, want to choose a newer Wi-Fi system separately, or need its 2.5GbE port for a compatible wired setup. Pick Motorola MG8702 if you want a single device with four Gigabit Ethernet ports and built-in dual-band Wi-Fi. The integrated arrangement reduces equipment clutter, though a separate router gives more flexibility when upgrading wireless coverage. Both require cable internet and provider approval, so compare the exact model against your provider’s current list before checkout.
Do Motorola MB8611 and Motorola MG8702 work with every internet provider?
Motorola MB8611 and Motorola MG8702 work with compatible cable internet service, not every type of broadband connection. Cable providers maintain approved-device lists, and model support can depend on the speed plan and local service configuration.
Check the provider’s compatibility tool using the complete model number before buying. Also ask whether activation requires a support call, whether the plan supports the modem’s capabilities, and whether the provider charges a modem rental fee you are trying to avoid. Neither device is a replacement for fiber or DSL equipment. A modem purchase does not guarantee a faster plan: your subscribed service, home wiring, Wi-Fi placement and connected devices all affect the connection you experience. Confirming the exact service type first is the easiest way to avoid a mismatched purchase.
Is a modem-only device or a modem-router combo a better buy?
Motorola MB8611 is the better modem-only choice for people who already own a router, while Motorola MG8702 is a better combo for shoppers who want one device. Those formats serve different needs, so a higher Wi-Fi number does not make one automatically right for every household.
A standalone modem lets you replace or upgrade Wi-Fi without changing your cable modem, and it suits mesh systems or advanced router setups. A combo can simplify installation and reduce the number of devices and power outlets in use. Motorola MG8702 uses Wi-Fi 5; NETGEAR Nighthawk CAX30 adds Wi-Fi 6 for households prioritizing a newer wireless generation. Before buying a combo, consider whether its wireless coverage suits your layout. Large homes, dense walls or distant rooms often need carefully placed access points or a mesh system, regardless of the router’s class.
What should shoppers compare in Black Friday 2026 cable modem deals?
A good Black Friday 2026 cable modem deal matches your provider, plan and network needs before you compare features. Start with compatibility, then identify whether the product is a modem alone or a complete modem-router gateway.
For a modem-only device, check the Ethernet port speed and make sure your router can connect properly. The Motorola MB8611 and ARRIS SURFboard S33 both include 2.5GbE; the S33 also has a 1GbE port. For combos, compare Wi-Fi generation and wired ports. Motorola MG8702 has AC3200 Wi-Fi 5, while NETGEAR Nighthawk CAX30 has AX2700 Wi-Fi 6. A high wireless class does not promise the same speed in every room. Read the return policy, confirm the exact product variant and include any separate router needed in your comparison.
Which modem is the best long-term choice for cable internet?
Motorola MB8611, Motorola MG8702, ARRIS SURFboard S33 and NETGEAR Nighthawk CAX30 all use DOCSIS 3.1, making them stronger long-term starting points than the DOCSIS 3.0 Motorola MB7621 and Motorola MG7700. Provider support and plan fit still determine whether a modem works for your home.
For flexibility, a DOCSIS 3.1 modem paired with a router you can update separately is a sensible route. The Motorola MB8611 provides a 2.5GbE port, while the ARRIS SURFboard S33 provides 2.5GbE and 1GbE ports. For one-box convenience, compare the Wi-Fi features of Motorola MG8702 and NETGEAR Nighthawk CAX30. A future-ready label is not a guarantee of service speed or permanent provider support. Check the approved list when you buy and again before changing service tiers, especially if the new plan has different equipment requirements.
