The Motorola MB7420 is best suited for use with internet plans that offer speeds faster than 50 Mbps. Its 16 upstream channels can download data at a speed of 686 Mbps. One of the modem’s standout features is its full-band tuner, which can identify the channels with the least amount of traffic and focus the work through them. The Motorola MG7550 modem and router combo device also shares this tech. This feature is particularly helpful in a home or office with multiple open connections – you don’t want your modem to cut out because there are too many people online simultaneously.
The MB7420 is compatible with the largest cable internet providers in the U.S., including Comcast, Charter, Time Warner, Cox and Bright House. This is not the cheapest high-speed modem, but it costs less than $100, which is less than what you pay to rent a slower modem from an ISP for a year.
This modem has a vertical housing design that doesn’t take up much shelf space, and the multicolored LED indicator lights on the front panel are easy to see against the black background. The front panel lights include indicators for Ethernet, internet and power connection, as well as notification of upstream and downstream content delivery.
The indicators are symbols and more complicated than on other high-speed modems like the Netgear CM500, so make sure to familiarize yourself with what each one denotes. The user manual has a description for each symbol and a definition for each color the symbol can turn. If you misplace the user manual, it is available as a PDF download on the manufacturer’s website.
Motorola made the setup process easy by color-coding the four sections on the back panel. The power section has an input for the supplied power cable as well as a power switch. The MB7420 also has a unique lightning and surge protection feature, which is important for a cable modem because of the proximity of cable lines to power lines.
Below the power section is the reset button, Gigabit Ethernet port and coaxial connection. The retail packaging includes a wrench to tighten the coaxial connection, but we suggest using this wrench with caution. The coaxial cable does not need to be any more than hand-tight. If you tighten it too much, it could easily break the surrounding plastic, resulting in an unreliable connection.
The MB7420 comes with a two-year manufacturer warranty when it is purchased through an authorized Motorola dealer. If you have questions, you can contact the manufacturer by either email or telephone. The telephone support center is in the U.S. and is available between 8:30 a.m. and 10 p.m. Monday through Friday.
The Motorola MB7420 is a good investment for someone who has a high-speed internet subscription and wants to stop renting a modem from their provider. Motorola offers a two-year manufacturer warranty to increase the investment value. That is the longest warranty term offered by a modem manufacturer.
