Customer Ratings & Reviews

Solid performance. A little more advanced then I currently need, but happy this modem can perform when I upgrade my other equipment. I didn't want to buy a modem that I'd have to replace in the near future. This one will grow with the demands!

We wanted to stop spending money renting a modem from our internet provider. This modem was on the approved list from our IP and also recommended by the Best Buy associate. After 2 months of use, we are still happy with its performance.

This is the most modem I have ever laid eyes on. It is able to suck all of the bandwidth from my entire neighborhood and deliver me the fastest Wi-Fi of everyone on my street. Would recommend it to anyone looking for the fastest speeds possible.

I've had this modem for almost a year and it has been great. I've upgrade my speed to 1 gig recently otherwise I'd still be using this modem.

The installation and operation of the SURFboard modem is easy and fast. Once installed it is hands free and solid operational. I recommend this product instead of your ISP's modem.

I bought this to replace the rented unit from White County Cable. Will pay itself off in 7 months. Basically a plug and play unit. Only had to wait for the cable company to set it up in their system (about 2 hrs).

This handles ALL of needs, Optimum cannot throttle back our service in these times of high usage,such as the on-line schooling going on now. Does everything we need and more!!

This modem is a beast. Never realized how much speed I was missing for the internet plan I have been paying for. On my previous modem I only got 90mbps but with this same modem on my same plan I get 343 mbps.

So far the modem has been good. When I called comcast to activate it for some reason it wouldnt work at first but it took like 10 minutes to work. After that it was great. I have a Apple Tine capsule hooked up as a router and everything flows!

This item was very easy to set up, also fast.Modem doubled the upload and download speeds for my internet. Modem is lit with info for connection and is a very durable product. I would definitely recommend this item to other people.

Great modem. Motorola is a brand name you can trust and has been supplying this gear for 20 plus years. Easy install. Noticeable speed improvement. Purchasing this model assures your set with the best technology for a while. ROI is ~ 18 months.

I purchase this modem after suggested from Time Warner Cable. It is supporting up to 300 MBPS which is very nice. Earlier my home internet speed was only 15 MBps and now after using this mode, I am getting 60MBps at my home with same plan.

My old Time Warner Cable router was starting to malfunction after several years of operation. I bought this one given the positive reviews I've seen on other sites. It works quite well on it's own, as well as in tandem with my Linksys router.

Not much to say about this little guy, except that it's a screamer and it connected up to Comcast cable without a hitch. Well worth the money!

We have 200+mbps and this modern catches it all. Longest part of setup is calling cable company to register it to your account. Get the service pkan. This is my second unit because the first just fizzled & the service plan saved $$$.

I switched from renting one from WOW cable and I couldn't be happier. It's practically fail proof. When the power surges or goes off, it automatically re-boots itself. I don't have to go disconnect it and wait the re-connect and hope.

Went to Best Buy to get a new Modem. Sales rep was very helpful in accessing my new needs and recommended this model. Bought and easily installed it and the Arris Surfboard 600 is meeting all my needs. Very Pleased. Thank you.

My old modem was the slower version. It died when we had a wind storm and power outage. I had the power plugged into a surge protector, but the power glitch knocked it out anyway. I'm guessing there was also a surge on the cable which had no protection. I'm now using a power strip that also has surge protection for the cable. The new unit seems to work fine.

I purchased this router in anticipation of my internet provider increasing my internet speed. It replaced the same brand, but a lesser model. Both worked and are working flawlessly.

I was looking for a cable modem without wireless router and this product is exactly what I was looking for. Setup was very easy and works very well. Great product and big cost saver as opposed to renting a modem from Internet provider.
