Customer Ratings & Reviews

Better solution compared to an all in one router/cable modem/wireless. Had 2 all in one units before and they failed quick. This seems to rate as more reliable. Much higher performance also.

Works great for Comcast. I use it with an old Apple Airport Extreme. No complaints for the price/speed.

I had an very old modem for a long while and recently updated to this model. I have not had a single problem since I installed it. I am experiencing faster internet and no connection drops.

I just upgraded from the SB6121 because it keeps loosing signal and my internet connection, It was worthy now everybody at home have a realiable connection and my kids stop complaining!

Picked this up to replace the unit our cable company issued us. It was super easy to install. Just called the company to activate, and it's been up and running ever since.

I really like this modem because it is trouble free. We were looking for equipment that is better than the rental equipment provided by cable companies. I am very satisfied with this modem.

Worked very will the Google router and point. Spectrum modems will not give you the speed that you pay for. This modem is excellent

I did a little bit or research before I purchased this. And so far it has worked awesome with no issue and no speed drop. I made the purchase to not have to rent from my cable company.

Got it to replace an existing same-model Cox modem and it worked like it should. No issues and worked out of the box. Internet is back up.

Bought to replace the TWC rental cable modem. Will pay for itself in 9 months. Had TWC rep on the line during setup, which went without a hitch. Works at least as well as the TWC modem.

All around an excellent modem. I have had no complaints. It does it's job and it does it well. Only issue I've ever had has been due to my ISP.

This new DOCIS is the update to last years modem. It portals the connection from my COMCAST service with eye blinking speed. So glad I made the less than a year upgrade. It is so worth it.

Easy to setup. Fast connection. It was easy to setup and get going with Comcast. Highly recommend this modem.

Instead of renting a device from your provider you should buy a modem and separate router. This device will allow you to take full advantages of any speed offered by Comcast/xfinity.

I had it with renting the modem from my internet provider because of continued problems and bad customer service. I love this modem it works (0:

SB 6183 is a very robust modem. Its small and light weight. I bought the one in white. I use it with TP Link AC 1750 router. Price is expensive at $110 at Best buy inclusive of taxes.

Great modem. I’ve had this for 6 months and it works great. Fast speeds. Does everything I need it to do. I would recommend it.

I wanted to buy a modem so I didn't have to pay for a lease fee then I realized it has better stats than the one I was given. Now I actually get the 300mbps I pay for. Love the modem, hate TW

I decided to buy my own cable modem when changing to Xfinity instead of monthly fees. This one has plenty of speed for downloads and pays for itself in the first year!

Upgraded my internet so this little guy supports the faster speed but i might upgrade again soon. Also i wish it came in black
