Customer Ratings & Reviews

Let's face it: Best Buy is the best place to buy cable modems so that you might save a ton of money over getting them anywhere else. This ARRIS cable modem performs better than any than I've ever used, taking full advantage of the highest speeds available through my carrier. It's easy to set up and its numbers and codes are easy to read and report to your carrier when connecting.

Awesome 3.1 router.Wentahead and future proofed myself and got the 3.1 even though 3.0 is all that is needed for this area.But eventually you will need 3.1 so go ahead and get this one.Great modem and real easy to connect.I can tell you it works worth Comcast and WOW.Might want to catch it on sell as it wasn't when I purchased and had to grab my ankles.

I purchased this modem as I had received 10 years out of my old modem and thought that having updated equipment with the latest docsis 3.1 support would be able to get me another 10 years before having to buy another modem. All I had to do was contact my cable company and give them the new MAC address of the modem and I was up and running in about 10 minutes.

Excellent modem. Decent price. In stock at local store. Not too difficult to set up and get operational. Biggest problem was dealing with the local cable company!

Arris create a great product. Ive been using their modems since 2015. Ive only had one modem go out in that time. Their menu is extremely wasy to navigate and if you like the technical details, then you have a lot of information provided by the interface. I was able to self diagnose the modem failure when it happened. Which if anyone has dealt with comcast sometimes can be a drawn out proces just to get a technician there. I recommend this product over anything else.

very good speeds and good quality. easy to set up and use.

Easy to use, install. Works well with xfinity. Internet is definitely faster

I am moving from an all in one modem that would cut out all the time, to this beast! To be fair my network setup is about 3x as expensive now, but it was completely worth it. Using this modem, a pfsense router and intrusion detection system, and a unifi AP wifi unit, my network is more secure, more reliable, and actually much faster!

Perfect for the application required. It was simple to connect and only rebooted for unrelated siagnostics.

Easy to install. Worked immediately. It's giving us much higher speeds than our 3.0

Once we got this modem set up (just needed a simple call to the Interbet Provider) it went online without any issues! Our intenet comes in faster than ever thanks to this modem!

Really fast speeds I was able to increase my speed by 2.5x and it was easy to set up and it took about 45 minutes which included contacting the ISP.

I was using an old 4x4 SB6121 for the last 6+ years. Chose it because of the price. Didn’t know what I was missing. This one is so worth the upgrade. Two kids streaming vids and both the wife and I working from home, we no long have lag issues. Yes, it is on the more expensive side, but with DOCSIS 3.1 you are good for years to come.

Fantastic purchase. Would definitely buy again. Highly recommend

Easy to install, great speed, no reboots so far, would recommend to a friend

Great up from docsis 2.0 from 2005. Speed is great and cable guy said this will be good for years to come. Forget paying the modem rental fee. Call the cable company and they swapped me out on the phone in about 10 min

Our modem shot craps and they recommended getting our own Docsis3.1 since it would have been 2 weeks to ship a new one. Picked this one and it's been great. Faster. Reliable. No more rental fees. Just remember that you'll have to call in the MAC address to your ISP to get it active. Otherwise, it was plug-n-play. Recommended!

I have to say the Arris surfboard is awesome. I stream often and has not had any issues. I increased my speed to 400 mpbs through my internet provider and I could not be happier with the Arris modem lightning speed.

Purchased this modem to replace the cheap, $10/month rental provided by the cable provider and to support my upgrade to gigabit internet. So far it's been fast, consistent, and smooth. I connected Google WiFi for wireless access, and the two have been stellar in supporting my desktops, laptops, tablets, and 20+ Smart Home devices. Very pleased with this product.

This is a great modem. The product itself is easy to hook up, although Comcast gave me trouble trying to do so. I have had no issues with it and don't have to restart all the time like I did with the rental from Comcast. In the long run, don't give your money to Comcast and buy this modem with a separate router.
