Customer Ratings & Reviews

We were upgrading our internet speed and needed a faster modem. Found this on the Best Buy web site and it looked like just what we needed. I mentioned it to the cable installer and he agreed it would work with our new service. Hooked everything up and I haven't had a problem considering we have 3 laptops, 3 smartphones and 2 tablets running in the house.

Great modem and easy to set up. I'm getting great speed with this unit. Works well with my router.

This device was very easy to set up and works perfectly.

Picked this up to replace an old SB6121 that wasn't keeping up with Spectrums speed increases. Installed it called to get it registered. Took all of 10 minutes. Download peed increased from 112mbps to 235. If you are paying for the speed but not getting it replace your old modem!

This modemn was easy to connect and is compliant with Xfinity wifi. It appears to be reliable without disconnecting often.

Good modem. Reliable. This is my third Surfboard model.

I would recommend this modem to anyone who wants High Speed Internet and or fast streaming! Do Not Use The Providers Modem! The ISP Provider Controls their modem by altering the Init Strings in the modem to restrict your data speeds. They cannot do this to a Privately Owned Modem due to FCC regulation of Modem Init String Tampering! You want the speed you pay for? Buy this FAST Arris Modem! Highly Recommended!

The Modem is fairly basic in terms of the indicator lights but it works well and gets me 300 Mbps. Obviously I have a high end ISP that provides me with that speed and this modem is a champ as maintaining it. Up stream is great too with room to grow. This is a great modem to own if you think you may have gigabit internet coming to your area soon since it can handle so many channels at once. Not exactly Cisco quality but I'd recommend it.

Great product, easy to install and performed exactly like the DOCSIS 3.0 modem was described.

Great purchase, upgraded from old modem and is much faster with no interruption of signal.

Easy set-up. Called TWC and that was it. Great complement to the Asus AC5300 router. Increased speed

This is a great modem and the speed with my cable service is unbelievable! Works like a charm!

this is a great modem. have not had any problems with it at all. fast speeds and very reliable

My speed really improved with this modem and I have no trouble connecting to Comcast with this modem.

Excellent! Produces a very solid connection! No lagging.

FAST .... RELIABLE... DOESN’T DROP CONNECTION. great modem

This is a very good, reliable, easy set up modem. Plug and play. No issues or difficult setup.

I purchased this modem to both upgrade my cable company supplied modem and to cease paying rental fees. After installing it, I immediately noticed a major change in downloading and uploading speeds. I also received much better range with my wifi enabled devices. The cable company representative told me that in his experience the modem is "one of the best out there." I would highly recommend the unit based upon my experience with it.

I thought long and hard about buying a $300 DOCSIS3.1 modem, but decided that they just weren't ready for prime time yet. Instead, I spent $100 on this guy and am getting speeds averaging 230-240 Mpbs on Comcast via hardwire connection. I don't regret not future proofing - I'm sure I'll get the latest and greatest and 4-5 years. This connected to Comcast with the typical activation call and was ready to go in about 10 minutes.

Probably the fastest and easiest moden to set up!!
