Works as expected, no issues.

The cable company loaner router rectified the issue and it has not gone down since

No service issues, easy to connect to Comcast and internet speed are extremely fast.

Cox told me the serial number is not one issued by Motorola and the serial number is not in the format for the MB7621.Cox then told me the signal was sent to the modem but the modem couldn't read it

no issues easy install..

Now COX blames every issue I have on the modem.

Hopefully this cures my network issues that I suspect were caused by faulty Arris

No issues works great love the parental controls

Easy to install, I had no issues.

When Comcast came and removed that, this just fired right up and worked, no issues

The new one has no issues so far, easy to set up, runs cool.

No issues, cheaper than renting in long run.

Product works well, no issues after using it the past 2 months, Fast throughput.

Works as expected, easy setup on XFinity service, haven't had a single issue with it

I’ve not had any issues with this, thank goodness.

Router works great no issue so far but when I activated with Comcast I was told this product is at end of life cycle and might have problems later on.

The modem was causing my internet signal to dip in and out after I had the tech support come out from optimum three times and charge me with a tech visit of $80 to tell me that and thought it was a weak signal issue

Just works, no issues so far.

wanted to use with the switch but was hard to configure and even tech support had an issue with it working they got it to

Works well with COX; no issues so far.
