Customer Ratings & Reviews

I have Cox in Phoenix, AZ. I use their Premier (27 Mbps) it is one step below the "ultimate" and requires the "stream combining" to reach the advertised speeds. I was dubious that it would make much of an impact. I run this in to a and the results were suprising. I ran a test over wifi with my iphone using the speedtest app. On the old modem I got about 20 Mbps down and it says about 30 Mbps up (I think upload is way off for whatever reason), ping was about 70ms. AFTER the install of this modem I saw about 30 Mbps down and 45 up, Ping dropped to about 35ms. This is all annecdotal and based on wifi and an iphone app, but I did notice a much quicker response on all items connected. Xbox, Roku, iPad, all loaded faster and i have been killing it on !

Great modem for Comcast Internet. East to setup. No problems with connectivity. Great speeds as I get more than what I signed up for.

I got tired of paying Comcast every month to rent a modem, so I decided to buy my own. I bought this modem, plus a Netgear router, and the combination resulted in a significant increase in speed. Very easy to set up.

Easy to setup and connect to my wireless router as well. Upgraded from a older model that got destroyed from a lightning strike and this produces the same great performance.

This was the easiest install that I have done. More reliable than the internet supplier modem and able to support speed upgrades if I choose to do them in the future

This modem was purchased to replace the rental cable modem on my monthly cable bill. Works perfectly, easy setup and communication with existing cable company. Smaller than the cable modem it replaced and runs cooler. Pays for itself in 5 months!

Easy to use, inexpensive and dramatically faster upgraded Modem then that supplied by my cable company and over the near term pays for itself verses cable company rental fees. Easy to install and a pleasure to use!

Although a bit pricey up front, you will easily save money in the long run. Delivers excellent speeds, more reliable than the hardware your ISP provides you, and it feels good just to not pay those "rental" fees anymore.

I’ve had this modem for a couple weeks and so far, so good. It was reasonably priced and delivers the full speed of my cable internet. Plus, it saves me $11/month in modem rental from Comcast.

You want the fastest 300 Mbps speeds from your ISP then this modem is a must. Reasonable price to own your own saving the monthly rental fees. Works flawlessly, no issues, delivers speeds as advertised, highly recommended.

I bought this modem to replace my Arris SB6190. So kinda downgraded it. Best decision ever! I was having many problems with my internet such as slow speeds, dropping connection, etc. Had multiple service calls and they came out to diagnosis the problems. They got the cable lines perfect. Well come to realize the problem was the SB6190 which after hours of researching the modem it seems that many others are having the same issue. I set up the new Arris SB6183 and all the problems went away! I wish I would have known this years ago! I highly recommend the Arris SB6183. It has also been a top pick for modems of 2019!

Decided to change my Comcast modem for my own modem. Best buy staff were able to help me chose the correct modem for Comcast and also a router. The modem was a great price and was easy to set up.

This is a great deal for the money. Has 12 channels and great max speeds. Unless you need a Gig downstream speed, this is all most people will need. Beats renting from Xfinity as well.

This modem is just too of the line. Purchased to replace TWC rental modem router. Currently using with Asus RT AC-3100 and Internet download speeds are going up to 350mbps from a 300mbps plan. Totally worth it.

This modem is easy to set up and the indicator lights are basic but good. It works well with my time machine. The speeds it can handle are higher than what I get from Comcast now so there is plenty of room for growth.

upgraded from a SB6141 to the SB6183 due to Time Warner bumping up Internet speeds. Easy install, quick call to TWC to register the modem with them and I instantly went from 22mbps down / 5mbps up to over 230/22.

More than adequate for my needs Salesperson led us to the product that was adequate for us. Did not try to sell us something we didn’t need

Why rent a modem for $11/month when you can own a perfectly good, reliable, and fast purchased modem for $69. Works great and I've had no issues with speed or not working!

When TWC started charging almost double for modem rental, I decided it was time to buy my own. This modem meets the requirements for TWC's highest speeds, was a simple phone call to install. Totally satisfied so far.

I got the Arris SURFboard 600 to replace Time Warners modem and I am glade I did. It is super easy to set up and much faster then what I had before. The cool thing is it lights up then the lights are low.
