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've had this for almost a year now and still working at %100 no dropping dual channel lets you have a computer hard line to the modem and lets you use a router also service provider may depend on dual port usage. you can not use a play station or xbox if would want to dual port you cant those need to be on a router when hooking my ps4 to the device with out the router it makes the modem only allows one device hard wired if using consoles,PC you can use both channels for 2 PC's on the modem. the picture is a speed test with direct modem connecting i got the 940mbps and 30mbps connection

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.
