ARRISSurfboard SB8200 DOCSIS 3.1 Cable Modem, 1000205

I got this several months ago and have had no real problems and very good speed. I run a tri-mesh with this and in my small home and property I have perfect wifi! Only one time did I have to unplug this and restart it. Very satisfied!

Compatible with Comcast/XfinityReasonable price for current tech

I've purchased renewed, at Amazon with hit or miss results!The Surfboard 8200 was a MISS!The modem was installed, several days before the return window closed, due to health, & tenant issues.According to xfinity the modem was not operational because it would turn on & off continuously.So the immediate thing to do was to order a replacement, for my tenants, which was a hit unlike the Surfboard 8200.It was also renewed & has been operational since installation. So A HIT!When I tried returning the failed modem, 2 of Amazon reps were unprofessional and would not even listen to the fact, the modem DID NOT WORK, regardless of whether I missed the return window.So beware of renewed or refurbished. I am now, but I'm still irate over NOT getting a refund for a dead modem & the unreasonable reps that would not understand IT NEVER WORKED! Contrary to the description!Beware!!!The 1 star is for the seller! Amazon unreasonable reps didn't even get thanks because they ended the chat.I'd like to report them!

I upgraded from the previous generation DOCSIS 3.0 AARIS Surfboard to this 3.1 version and the up / download speeds are a dramatic improvement. 3.0 gave you 8 multiplexed channels while 3.1 gives you 30. I went from 8 - 10 MBs UP to 57MBs. Downloads went from 180 MBs to 598MBs. That said I never had any previous buffering issues, but now there are none. More speed may be possible as the cable company just asked me if I wanted a free upgrade to the house amplifier. [COX]. While I don't need more, I'll take it. Also, no overheating issues as others have mentioned. Good upgrade!

This upgrade allowed me to get faster internet connection. There are many ports on the back that lets hardwire some systems.

Easy to install and works like it should.

Compatible with xfinity/comcast internet service.

A good modem should be easy to set up and should work well (basically set it and forget it). That describes this modem. It works exactly as it should.
