Customer Ratings & Reviews

Works very good and easy to set up with cable company.

Pretty good. Called cox to activate, I feel like Im getting the maximum speed out of the wall. I payed for 100mbps and was getting 110-130) downgraded to 30mbps, still get around 35.

Had no issues at all with this modem. Very reliable, don't have to pay the cable companies stupid rental fee, and you are in control of it so you can log in and see what levels it is pulling and etc.

I had to upgrade my router since my cable company has change their modem to 3.0. So it was amazing how fast it has change with my router asus. Would recommend to others.

I upgraded my internet speed and needed a different modem to take advantage of that increased speed. I have always had good luck with Arris Surfboard and this one was no exception.

I bought this, plugged it in, configured it with the cable company....and haven't touched it since. That's exactly what I needed, something that works with zero hassles.

Was looking at modem router combo units but went with separate units instead. This modem is small, but extremely capable of high speeds and worth the extra few dollars over the 6141 model. I highly recommend this modem!

Got this so I didn't have to continue to pay to rent a modem from my internet provider. This was quick to get connected and running with no problems after registering it with my internet provider.

recommended this to my mom who is switching providers and did not know you could bring your own modem for a low price and beat the rental fees. This is the only way to go!!

This little modem works great. I use it with my internet provider, Cox. Works great for 300megs. I checked my speeds with the app Speed Test and is giving me 289megs on average.

easy to set up, works fine. I use COX network, there were two network disconnection until now (about 1.5 months). Not sure if due to cox or cable. Problem was solved by simply unplug and plug the power adaptor.

I got this for my optimum internet hook up and had no problems whatsoever. I’ve had it for a month now and it works really well. I’m happy with the product and hesitate to purchase it again.

I was tired of renting a modem from our cable company. I bought this item and it's worked great. Amazing speed and none of the outages I am used to experiencing with my old modem. Buy this item and reduce your cable bill.

This was exact replacement from what we “rented” from cable company. Will be paid for in 7 months. Installation was easy and a phone call to cable supplier with proper numbers was fast and easy.

We use Time Warner Cable, and using this modem enabled us to go from 50 Mbps download to 300 Mbps... I thought DOCSIS 3 modems were all alike, but each provider seems to use different ones... Check with them first.

Bought this modem to replace the cable companies supplied phone/internet modem. Easy install. Still needed cable modem for phone service, but no longer charged monthly rental charges. Should have done this years ago

Other than an occasional blip in connectivity (which I attribute to our inconsistent internet provider, this modem works flawlessly. We have had no problems with it and it is a workhorse in the background as it should be.

This modem performs as well as the free one from the internet company. When wired, I see a significant increase but when wireless, I still see similar results as before even after buying a much better wireless router....could be the service, if I'm being fair.

What a difference in this and the old modem I was renting from Time Warner! Wow! speed is great and connection stable. Sometimes what you don't know can hurt you. I had no idea how bad it really was. Love this modem.

Cox Comm hasn't implemented IPV6 in my area so it's not running full capacity despite my premium high speed service but still faster than any other modem even the SB6141 it replaced. Great product as always Motorola/Harris!
