Motorola MB8611 DOCSIS 3.1 Multi-Gig Cable Modem Review

Motorola mb8611

The Motorola MB8611 is one of the fastest modems in the market. With blazing fast gigabit internet speeds along with the modern standard of DOCSIS 3.1, the modem is a strong contender for being among the best of its kind. It shares a lot of similarities with the Motorola MB8600, including the design.


Just like its sibling model, the MB8611 is backward compatible with DOCSIS 3.0. It also supports a huge number of devices and almost every leading internet service provider, such as Comcast Xfinity, Cox, etc. Also, thanks to it being a DOCSIS 3.1 cable modem, the device is future proof, further enhancing its compatibility.


The Motorola MB8611 DOCSIS 3.1 proves to be an excellent modem when it comes to providing consistent bandwidth. With low latency, minimal packet loss, and low ping times, high speed internet can be accessed at all times. Its 2.5Gbps ethernet port can reach a maximum speed of 6Gbps if DOCSIS 3.1 is available.


It has 1 2.5Gbps ethernet port and a WAN port for coaxial cable. Although this is disappointing, one port is just enough to get the job done in most home applications. The MB8611 makes up for it with the multi-gigabit port, a slightly rare option among most competitors.


As you may have guessed, the Motorola MB8611 DOCSIS 3.1 does its job perfectly. With super-fast upload and download speeds, the modem also features an active queue management system. Whether online gaming, video conferencing, or video streaming, the modem is sure to give consistent bandwidth.


The experience of installing and setting up the MB8611 is very similar to its sibling model. No technical knowledge is required. The modem can be set up in just 3 steps; connecting the coaxial cable in the WAN port, switching it on, and connecting it to a computer!

Now that we more or less know about the MB8611, the modem is a substantial upgrade over its sibling, the Motorola MB8600. But how big is the difference? Is the extra price of the MB8611 justified? Find out as we head to a detailed comparison between the two.

Advantages and Disadvantages of MB8611

A lot of people debate on whether the MB8611 is a good upgrade over the MB8600. Here are its advantages and disadvantages:


  • Exceptional performance and reliable internet access
  • Highly resistant to power surges
  • Ultra-fast 2.5Gbps ethernet port
  • Modern standard of DOCSIS 3.1, also supports older versions
  • Excellent compatibility with nearly every internet provider


  • Only 1Gbps port; deal breaker for users with multiple IP devices
  • Not as cost-effective as its cheaper sibling

Key differences between MB8611 and MB8600

Although there are a lot of similarities, they differ from each other in the following aspects:

The Motorola MB8600 comes with multiple ethernet ports, while the Motorola MB8611 has just one 2.5Gbps port. When it comes to speed, the latter provides much faster upload and download speeds. Whereas the former can support more LAN devices.

Data Transmission Speed
Although this is not a concern to regular users, for raw data transfer, the MB8611 is capable of up to 6000 Mbps speed, while the MB8600 maxes out at 3800 Mbps.

Wired Speed
Without a doubt, the Motorola MB8611 excels when it comes to the raw performance of its multi-gigabit ethernet port. Moreover, it also ensures minimal latency with its active queue management system. Although the difference is not significant, the Motorola MB8600 does slightly fall back in terms of performance.

With the key differences out of our way, the following section will cover a list of the pros and cons of both devices. Keep reading and be the judge of which is the better modem!

Which One Should I Get?

The price difference between the Motorola MB8600 and the Motorola MB8611 is not too much. But the differences in their features set them apart for different application scenarios. So, which one should you get?

Let’s start with narrowing down the potential consumers of the MB8600.

If you have to connect multiple static IPs and need to connect a WiFi router, a game station, etc., to it, your only option would be the MB8600 as the other model has only 1 ethernet port. It also excels in cases where multiple ISPs are used together.

The MB8600 is also the ideal choice for larger scale setups, e.g., in cases where you would have to set up a big LAN coverage, such as a dorm room. It is also ideal for online gaming as it does not slack in performance.

On the other hand, the MB8611 can give you much better internet speeds. It is ideal for corporate purposes where a high rate of data transfer is required. Moreover, the model also ensures minimal streaming latency.

But since it has just 1 port, the number of devices that can be connected is strictly limited. Also, for regular users, the price difference between the two models may not seem justified.

In simple words, the true power of the MB8611 can only be seen when ISPs offer gigabit internet services, which will definitely take time as people still rely on 100mbps and 150mbps connections.

Other Factors to Consider

One of the biggest drawbacks of the Motorola MB8600 is its 1Gbps ethernet port. As faster internet speeds are becoming more and more common, the 1Gbps limit will seem to be slow in no time. Some ISPs are already offering 1200+ MBPS connections, meaning that the device becomes obsolete despite having the technology.

Another problem that most users face is that the link aggregation support is quite difficult to avail. Technical knowledge is required to set it up, and users often end up messing up their internet access.
