Motorola MG7550 Cable Modem Wi‑Fi Router AC1900 DOCSIS 3.0

The Motorola MG7550 is a certified renewed 16x4 DOCSIS 3.0 cable modem with a built-in AC1900 dual-band Wi‑Fi router designed to deliver fast, reliable home broadband and reduce clutter by combining modem and router into one unit.

This renewed MG7550 has been professionally inspected and tested to work like new, and it’s approved by major cable providers (including Comcast Xfinity, Cox, Charter Spectrum and others). It pairs a 16x4 downstream/upstream DOCSIS 3.0 modem — capable of supporting common home speeds up to about 375 Mbps — with an AC1900 dual-band Wi‑Fi router that supports both 2.4 GHz and 5 GHz devices. The vertical, space-saving design and built-in Power Boost and beamforming technologies focus performance where you need it, while four Gigabit Ethernet ports let wired devices get full speed.

How fast and reliable will this unit make my home internet?

The MG7550’s 16x4 channel configuration increases downstream bandwidth and stability compared with older DOCSIS 2.0 modems, improving throughput and reducing congestion during peak use. The AC1900 router portion supplies combined theoretical wireless speeds suited for streaming, gaming, video calls and multiple devices. It’s a practical choice for many broadband tiers up to roughly 375 Mbps, depending on your provider’s plan.

• 16 downstream × 4 upstream DOCSIS 3.0 channels for improved downstream capacity
• AC1900 dual-band Wi‑Fi (2.4 GHz + 5 GHz) for broad device support
• Four Gigabit Ethernet ports for high-speed wired connections
• Recommended for cable plans up to ~375 Mbps; provider compatibility verified

Will this modem-router work with my cable provider and plan?

Yes — the MG7550 is certified or approved by many leading cable operators, so it typically replaces rental hardware without extra monthly fees. Before buying, verify your exact internet tier with your provider; the device handles a wide range of speeds but is optimized for DOCSIS 3.0 plans rather than the fastest DOCSIS 3.1 tiers.

• Approved by Comcast Xfinity, Cox, Charter Spectrum and several others
• Plug-and-play setup with most cable service accounts after modem activation
• Suitable for household plans advertised up to mid-hundreds Mbps
• Not DOCSIS 3.1 — check ultra-high gigabit plans with your ISP first

What features improve Wi‑Fi coverage and connection quality?

Motorola included beamforming to direct wireless signal toward active devices, improving range and throughput. Dual-band operation reduces interference by splitting older and newer devices across 2.4 GHz and 5 GHz bands, while the vertical design helps cooling and stable operation during sustained use.

• AnyBeam beamforming on both 2.4 GHz and 5 GHz for focused signal
• Dual-band operation to decrease congestion and support legacy devices
• Vertical housing for improved airflow and space efficiency
• Built-in firewall and Broadcom chipset protections against certain network attacks

What comes with a Certified Refurbished MG7550 and what warranty is included?

A Certified Refurbished MG7550 is cleaned, tested, and repackaged by qualified suppliers, and it ships with necessary accessories to get started. Refurbished units include a minimum 90-day warranty and may arrive in a generic box; check the seller’s return policy for additional details.

• Functionality testing, cleaning, inspection, and repackaging included
• Minimum 90-day warranty with eligible sellers on the renewed program
• Includes power adapter and documentation; box may be generic
• Sold by select high-performance sellers under Amazon Renewed program

Who is this for: The Motorola MG7550 renewed combo suits households and home offices that want to stop renting a modem, reduce device clutter, and support multiple streaming and gaming devices on plans up to mid-hundreds of Mbps. It’s a strong choice for users with major cable providers who need reliable broadband, wired gigabit ports for desktop or console connections, and improved wireless range without upgrading to DOCSIS 3.1 hardware.
