Motorola MG7550 Reviews


The Motorola MG7550 is designed to accommodate up to 4 wired devices at the same time. It also supports 16 download channel and 4 upload channels which mean you can have an incredible speed of 960Mbps with this modem/router combo device.


Motorola MG7550 is a combo unit, it does function as a standard Cable modem and Router. On the zip package, it says it’s a Wireless AC1900 but does note that this is not exactly true as it only has one wireless band of 2.4GHz which supports up to 600 Mbps data rate.

According to the Motorola website, the unit will automatically select the best available connection based on the capability of your device i.e 5 GHz for HD video streaming or 2.4GHz for Mp3 file download, etc.

It also comes with WiFi-GUARD technology that protects against online threats from all connected devices in your home network. The device is backed by 24×8 channel bonding capable of downloading at speeds up to 960Mbps and uploading at speeds up to 320Mbps.

Enhanced Connectivity

This modem will replace your existing ISP provided modem and provide you with a single WiFi network name (SSID) for all devices connected to this modem/router.

Your home wireless network is fully secured with WPA2 encryption which is the highest level of protection that is built into the device, it does not require any additional security setup by user .

Ease of Use

The Motorola MG7550 WiFi Cable Modem is a very sleek device and can be mounted on the wall with the help of a mounting plate that comes inside the box. It also has non-removable antennas which are 8 in total, 4 for each band. The user interface is very easy to understand with most functions accessible from a web browser.


The Motorola MG7550 is capable of download speeds up to 960Mbps and upload speeds up to 320 Mbps. We have tested the performance of this modem/router when connected directly with Motorola SB6141 Cable Modem or when plugged into our existing ISP-provided Netgear CG3000DCR cable modem, we were able to achieve these high-speed results in both scenarios. As for the WiFi range, the Motorola MG7550 is pretty decent and its wireless strength is much better than the device we tested in our previous review. The 5GHz band can reach through multiple walls in an average size home/office so you do not need to worry about dead spots.

Jacked-Up Speed

If you’re satisfied with your ISP’s service and not interested in switching to a new provider, we don’t think there’s any reason to buy a modem router. However, if you want to cut down on the cost of renting from your ISP or use more than one constantly streaming video device at once without frying each other out, this is a great option. It doesn’t have the 5GHz range extension seen in two-band models like the TP-Link Archer C9 or much in the way of extra features, but it’ll save you around $10 per month and has plenty enough speed and range for most home plans these days.
