ARRIS - SURFboard 32 x 8 DOCSIS 3.1 Cable Modem - White

So I upgraded my comcast internet speed to a much faster data plan which requires a new updated Docsis 3.1 version. I had a coupon and few bestbuy dollar reward and i figure, why not just get it from Best Buy. So the install was simple. Only Port 1 works, (i found out later). Port 2 will only work if you pay Comcast another dedicated IP address, which in my case I dont need. I had to call Comcast as the automatic sense and install didnt work for me. I gave the comcast agent the MAC ID of the new device, and VOILA! I had fast download and upload. The Unit runs very HOT, . To remedy this, I purchased the AC Infinity silent Fan from amazon. I sandwiched the unit as - fresh air intake fan, then the modem, then air exhaust fan. This will prolong the life of the unit as we all know, the component inside a Hot unit will degrade overtime from heat. Its been up and running for over a month now and have really no complaints. Highly recommended.

I have comcast internet and I was supposed to have 250 mb download speed but my Motorola sb 6121 was only letting me reach 140 mb download speed . I installed the Arris SB 8200 and my first internet speed test reached 301 mb download . Don't quite understand how a modem can do this , I thought it was the router that helped your internet speed , guess I was wrong .

I had an older model Arris and upgraded to this model and couldn't be happier. It has increased both download and upload speeds and added a huge boost while gaming online with both PC and Xbox.

Slim but mighty. I have Comcast Blast internet which is advertised at 300mbps and since I got my new Modem I average 353mbps. Great buy.

Replaced an ISP modem with the ARRIS Surfboard 32 X 8 3.1 Cable modem, and my internet access, and my internet speeds are vastly improved. This is THE modem!

I purchased the modem with the Orbi Mesh System and I gotta say I'm not disappointed in the least.

As the title implies, a DOCSIS 3.1 modem was required to handle the speeds of Cox Gigablast. Had good luck with my previous ARRIS modem so I went with what works.

Cable guy came, made a call, and set it up within 30 minutes. After he left it stopped working for 10 minutes then started working again. Have not had any issues since. I use Speedtest every once in a while at random times to just view speeds at different hours in a day and I almost always get exactly what I pay for even through WiFi. I would definitely recommend to a friend and save the $10 a month on the cable bill.
