Customer Ratings & Reviews

This is the first time I went and bought a modem rather than rented. Definitely worth it. I get the speed I want and have absolutely no problems with it. Easy set up.

Easy to set up, reliable, and I haven't had any issues with my modem since buying it. I would recommend!

Modem was easy to set up and works great with Comcast. I have been a customer of Motorola modems for 10 years now and have not had any problems with them; very reliable.

Motorola Arris SURFboard 600 series SB6183 installed easily without a problem. Allows my internet provider to max out on speed.

So far after getting this installed through my TV provider, this has been working fine. NO issues. No setup problems.

Excellent modem, works great for my use! Easy to install and works fine with Comcast internet service.

Great, easy to set up, works like a charm - have had no issues since purchase

This modem was very easy to set-up and relatively inexpensive compared to other modems. It serves the purpose in my household.

I'm signed up for 5.0 Mbps and apparently my provider is providing 7.5+ Mbps. This modem easily keeps up. plus it looks cool. lights up like a Christmas tree. LOL

Gives me good speeds and setup was easy. Only been using for a few months,so hopefully it will last.

I gave Comcast back their modem, put $12/month back in my pocket, plugged this modem in, turned it on, and that 's all I needed to do. As easy as tech gets. Of course Comcast continues to bill me for the returned modem and I have been fighting with them for the last month. I also bought a refurbished Tivo DVR direct from Tivo for $50 (plus their subscription fees), gave Comcast back their lame DVR, put $20/month in my pocket, and cut the cord. Couldn't be happier with the Tivo as well.

purchased this for my new tv i purchased. Does what it is supposed to do. Have had no issues. Does get warm to touch but read that is normal

My second Motorola, my first could not handle the 200 mbps to old I guess. Easy to install, had to call my provider (TWC) to activate and upgrade to 200 mbps, then I was up to blazing speed. My down load averages between 220 and 238 on most days. Can't complain.

Very fast. Very reliable. Good buy, don't buy the lower model than this. This is will handle the future speeds they are upgrading in most of the USA this year and next.

I'm using the Motorola Cable Modem with Time Warner and it is totally compatible with their system. I get excellent downloads and very good uploads. Highly recommended.

This Modem came highly recommended. its FAST!!!! don't pay a monthly fee to cable provider for a mediocre modem. this is a great modem at a great price

My previous DOCSIS 3.0 cable modem (Motorola SB6121) wasn't able to fully accommodate the 200Mbps from my ISP. My downstream with that modem was capped at ~150MB. This new modem has more downstream channels and will satisfy any speed increases in the foreseeable future. If I'm reading the documentation correctly, this modem should cover speeds upwards of 600Mbps. As soon as I provided the MAC address to my ISP I was up and running at greater than the 200Mbps that I'm paying for.

This is a fast modem. But (and this is important) it does not completely replace your Sparklight or other ISP modem. For instance, it has no firewall. If you connect a device to this modem, you had better have one of your own. Since I have an entire house and business running off of mine, I created a pfSense firewall and everything goes through it. If you don't have a hardware firewall, you will have to rely on your Antivirus or Windows Firewall.

I really like how easy Arris cable modems are to install, their reliability, and how long they last. I had my last one for 8 years (seriously) but have since upgraded my connection speed (70mps to 400mps) and needed a cable modem that could handle it. The more expensive model can handle way more than I need, so I found this one and its perfect!

It was easy to connect to my provider. Working better than the provider's. The best part is I own it, thus it goes where I go. Yeah!
