My internet stopped working and I power cycled my modem/router and computer and it still didn't work. Called Comcast and of course I had to power cycle everything again when I was on the phone with them. Still no internet. They sent a couple signals to the modem and tried to reset it but I wasn't receiving a signal. They suggested the modem was bad. Best Buy had one on hand so I ran over and picked one up. I'm thinking it's not my modem. I get home, hook it up and after the modem synced I was online again. So I was wrong, it was the modem and thank goodness Best Buy had them on hand.

I purchased this to replace my Time Warber Cable cable modem. So glad that I did! It saves me $10 a month and only cost $100. I'll break even after 10 months. It works just the same as the other one for me, but will work even better if your subscribe to faster internet speeds. Buy this jammy!!

Bought this to update my old surfboard which was only DOCSIS 2.0, if you are still using a DOCSIS 2.0 modem with your current internet provider you may not be getting the most speed available as companies are phasing out 2.0 modems. Upgraded to this and immediately noticed better speeds with Xfinity.

Even though with Gigabit is still a while away it is well worth it to buy this. It's $100 for a 16x4 and I got 35-45 Mbps with it but for an additional $50 you future proof yourself while experienced get super fast internet that pushed me into the 60s and as high as 73mbps. I may not even need gigabit

Worked for my needs. Faster than my prevous modem. Cheeper then renting.

The 32 X 8 was such an upgrade that I don't know how I got along without it. Much faster. Anxious to upgrade the router to see whether that will further speed things up. The discount for bringing the old one in instead of cluttering the landfill with it was also a plus.

I bought this modem after Cox repair guy left me with no service after trying to figure out why I was having problems with my connection. I decided to troubleshoot myself haven't had any problems sense making this purchase. Had no problems installing or activating this modem with Cox.

I got this modem to replace an older Motorola surfboard so I could upgrade to gigabit service. I also replaced an old router and have not been disappointed. It was a easy setup, just had to call my cable provider and give the mac address and was online in minutes.

I recently upgraded my service plan and got higher speeds that my old modem could not handle. Works great. First one I purchased was defective and would not connect to comcast but swapped out with BB customer service and the replacement connected immediately.

Easy install and price is affordable speed is great

I bought this device to replace my Arris 6121, as Comcast said my old modem would no longer be supported. So far, I haven't seen any issues with it, nor did I have any issues with my old Arris device.. Installation and setup was simple and I was back online in about 15 minutes.

I thought I was having issues with another cable modem I owned, so I picked up this SURFboard SB6190. It is fast and ended up being an upgrade to the Zoom 5341J I replaced. Turns out my issue was with my own router, so the upgrade wasn't necessary. I'm ok with it, though. Great product!

No problem setting it up, connected right away. Easy set up.

Picked this up to replace the cable modem provided by my internet provider. It was ready to go right out of the box. Confirmed the modem with the provider & I was online in no time at all. Happy with my purchase (& I don't have to pay rental on their equipment anymore!)

Modem price is not cheap but the xfinity internet set up is simple without additional steps outside of xfinity instruction

I previously was using an Arris SB6141. When I complained to my cable company that I wasn't getting the speed I expected, they said it's the router I'm using. I upgraded to the SB6190 and sure enough I got more speed.

Perfect replacement for my cable modem that used to cost me $10.00 per month...can't believe I didn't do this sooner. Very stable signal and works perfectly with my Linksys mesh router. Excellent modem for the price.

Upgraded from an older modem/router combo and I'm very happy with this one. It works great, never has to be reset like the old combo. I use it with a Nighthawk router.

Get your own equipment. This baby is small but it packs a powerful punch when connected with a great system. Free yourself from the $5.95 Comcast old dirty reused equipment fee.

The ARRIS Cable Modem works fine. It was easy to setup from my end. However, Cox had some slight troubles registering it (mostly Cox's problems). It has a high bandwidth throughput and works great for all the devices I have on my network plus is fine for streaming.
