Customer Ratings & Reviews

Setup was quick and easy with a call to the cable company. No problems with it at all. If I had a gripe it would be that the l.e.d.s on the front are a bit too bright. It's in a room that is dark most of the time and they can get distracting. But that's with pretty much all modems nowadays.

saved money over leasing and improved performance, solid performance and reliable speed and streaming

This is a great modem that allows Very fast speeds depending on your service provider. Getting a full 300 Mbps with my service provider which is what I subscribe to. Cable internet technician was impressed with the speed. Easy to set up. Would recommend.

I was leasing my modem and router from my isp and i decide to purchase my own. I purchased this modem and the linksys velop, mannn i completly love the new speeds. You wont be dissapointed, specially if you have in mind getting the gigabit internet. This thing will handle it with no problem.

Get if you are satisfied with medium speed internet. Typical users browsing and reading email can save money with medium-speed internet. I upgraded to 400 Mbps and a 3.1 modem improved speed by 20%. I went with 3.1 but I work online in an IT job. This older 3.0 version should be cheaper and work fine.

I purchased this modem 3 months ago to replace my 5 year old SB621 modem. I am extremely happy with it so far. Recently I upgraded my internet speed to 300Mbps and this modem handles it very well. The channel bonding functionality is great and works great! I recommend this modem to anyone without any hesitation.

Got this to replace my older Arris Surfboard because Comcast updated their system and my old Arris was no longer supported. After setup and installed, did a speed test and it boosted connection to more than double the speed. On phone with Comcast to setup modem for more than 1 hour but final result was worth it.

A Best Buy employee showed us several options - this was mid-range and sounded good. It was a good purchase. I'm really not a tech guy - but had no problems hooking it up. THANKS to Best Buy for the advice. Over time this is a better deal than renting the equipment from the Cable company.

Modem is an upgrade over the SB6183. Super fast speeds based on more up/down channels. While Cox is not able to take full advantage of the 32 down channels, you do get to take advantage of 24 vs. 16 on the SB6183. Translation = faster speeds. This device is future proof when the cable providers catch up to GB connections.

I love the technology therefore i like to have gastest products in my house. I want to recommend this modem becauseir is extremely fast but remember to purchase and excellent router this will be expensive but you will need it to sit down and the high speed data transfer will surprise you. A++ it is my review

I wqrk from home and when my existing Modem and Router gave me issues, I headed to Best Buy to look for a replacement. They had what I needed, and I am happily up and running again!

This is te best choice I found to go with my 300 mb internet plan because as I also have the NETGEAR - Nighthawk AC1900 Dual-Band Wi-Fi Router I wanted to have the top products for my service, this modem works splendid, it goes a little warm sometimes but it is normal and if I need to reboot it it does it very fast

LOve my cable modem. This thing is so stable and reliable....not one hiccup since Sept 2017. Download speeds of up to 1.4G. (of course, that's limited by your plan and your provider). This unit has space to grow as technology moves forward. I won't have to make any purchases to keep p.

Well it was time for us to upgrade our net gear router we bought 7 years ago from Best Buy. To this particular one. Easy setup easy install and now can handle our faster speed and current technology and our modem doesn’t keep going off and on and at weird times and less buffering !

I have one at my home to replace an old 6120. I also bought one for my office as well. It is a fantastic modem, and I get speeds above what I pay for, often 20% more. So, at the office, 75mps is what I pay for, but I get 90. Similar at home. Great stuff. It is pricey, but will pay for itself over the life of the product.

If you find out that you are not obtaining modem speeds or many devices are bogging it down then your problem could be the modem, not just the router. This router can handle 32 devices for downloading and 8 for uploading. Uploading would be kids playing online video games to clear that up.

Old modem died in a thunderstorm, had to get a new one. Easy to install and setup

Recently moved into a new home and needed to upgrade my system to handle higher speeds. Looked at various modems to use with my new xfinity account. After determining the requirements and talking with the Best Buy associate, settled on the Arris SURFboard DOCSIS 3.0. Easy install. Have not any issues.

This replaced my old cable model Cisco DPC3008 (5-6 yrs old) so really easy to setup just plug in, hook up cable and called Comcast. Comcast had it on their network in about 45 minutes. Just the modem my download speed went from 13 Mbps to 47 Mbps. Replacing the router next.

Only complaint I have about this thing is there are no mounting holes to put it on a wall or something. It surprisingly annoys me that they don't put these on the back or side somewhere. Other than that, works great and as advertised. Arris makes great stuff.
