My Honest Motorola MB8600 Review

The new modem is a significant improvement over the one I had before because of how quickly it can transfer data. However, Motorola’s poor customer service was a major drawback for the company. Over the course of the weekend and into the following week, I made many attempts to contact them for assistance. During each of these interactions, I waited more than two hours on hold and was informed that there was no technician available to handle my call before Motorola suddenly cut the line. Even after leaving a message, I received no answer.

I was able to get the system up and running after doing some independent research and ensuring that I had a robust signal from my internet service provider (ISP). Once I was able to establish a connection, I was required to reset my router, through the initial set-up procedure in its entirety once again, and then log back into my router.

To summarize, given the poor quality of Motorola’s customer care, it is strongly suggested that you get in touch with Amazon’s customer support first before making any attempts to communicate with Motorola. Although the Motorola MB8600 modem itself is a high-quality device, the fact that the manufacturer does not provide support for it is a serious drawback.
