Review on 💨 ARRIS SURFboard SB8200 DOCSIS 3.1 Gigabit Cable Modem, Cox, Xfinity, Spectrum & Others Approved, White, Max Internet Speed Plan up to 2000 Mbps by Leah Ramirez

I bought an Arris SB8200 for Xfinity gigabit internet service as they have a two year contract for the same price as the 400Mbps plan ($69.99). So, to save almost $15 a month, I decided to buy my own modem to replace my aging Motorola (Arris) SB6141. My SB6141 gave me 259 Mbps downstream and 35 Mbps downstream compared to my previous plan of 400 Mbps upstream and 35 Mbps downstream, which is great for an 8x4 Docsis 3.0 cable modem. So since Arris bought out Motorola's cable modem division I decided to buy another one as I have a great product in the 6141. The Arris SB8200 is also the only Docsis 3.1 modem with dual Ethernet ports capable of transmitting 2 Gbps and is the most promising proof of any other modem. modem on the market at the time of writing this review. And you can get a refurbished model for half price, which is even better! Inside the Arris SB8200 is a Broadcom BCM3390 chipset (a much-needed change from Intel's Puma 6 SB6190 chipset, which had hardware bugs and led to legal action). , 3GB RAM, 128MB S34ML01G200TFV00 Spansion NAND Flash and 16MB Macronix MX25L12805D SPI NAND Flash. The SB8200 supports up to 32 SCQAM or 2 OFDM downlinks and up to 8 SCQAM or 2 OFDMA uplinks (32x8 SCQAM and 2x2 OFDM). Ethernet ports are gigabit ethernet only, so the maximum speed you'll get averages out at 950Mbps, and that's never going to be possible with 10Gbps retail boxes. Even if you don't have a Docsis 3.1 or Gigabit internet plan in your area, this modem will serve you for many years. And this modem has 3GB of RAM while other Docsis 3.1 modems have 256MB or less! R.A.M! Oh, and most providers (including Xfinity) let you call them and add a separate IP address for a second Ethernet port for a small fee (Xfinity costs about $5.95 if I remember correctly). This would be great if you want to connect your gaming console directly to your modem for the best speeds and then connect your home router to the second. And finally, you can achieve speeds of up to 2 Gb/s by combining these two Ethernet ports! Setting up the device was quick and easy and you just plug the coax ethernet cable into your device (router for 99% of users) and turn it on. cable and off you go. A quick call to your ISP (Xfinity for me) to add the HFC MAC address, the modem is registered and configured and I'm up and running within ten minutes. Xfinity will attempt to ship the technology, but you can get them to overwrite it if you know what you're doing. Gigabit internet can be extremely temperamental as we will discuss later, for this reason Xfinity requires technology to be sent for all Gigabit plan installations. Again, it's just a modem. So you'll need a router if you need Wi-Fi or the ability to connect more than one device. The performance of the Arris SB8200 is top notch and I was able to easily get my modem speed from my Xfinity. Service. I was able to test 1.4 Gbps down (Fast.com also includes internal speeds as the actual one can be as low as 950 Mbps as mentioned above) and 45 Mbps up. On Speedtest.net, my tests almost always show 930-960Mbps (or so) and 40-50Mbps in. These speeds are AMAZING and only my download speed is faster than most people's download speed! At the moment Xfinity uses Docsis 3.1 for downlinks only, so the modem LEDs have a blue light for downstream and a green light for upstream (this is not a bug or a bug). I'm having issues with my Xfinity service and resetting, slow speeds (max 300Mbps down), etc. Xfinity sent tech support but it didn't work. So another cancer came along and found a lot of incoming traffic from 4 lines on my faucet. It blocked them and I started working at gigabit speeds again. Then discharges began, at night almost every 10 minutes! This only happened between 10pm and 7am on average, EVERY NIGHT! I had more technicians, supervisors, and more supervisors! After a month (and many hours of my time and talking) the problem was solved as it was a bad line amp causing noise and causing my upstream to go into the high 50's resulting in a modem reset and t3/ t4 led. Mistake. Now my neighbors were having problems with some channels and slow internet, but their modems WERE NOT RESET! And we knew my modem wasn't bad as it worked 12+ hours a day with no protocol errors until night fell each day. And in fact, my neighbors NEVER lost internet, but my internet was almost useless at night. The Arris SB8200 is extremely sensitive to t3/t4 errors, and the error and reset threshold is significantly higher with Xfinity gateways and modems. Also, Arris previously had a firmware update due to severe t3/t4 error sensitivity and I had the latest version but was still having issues so they still need to work on it. If you are having trouble with your Arris modem, go to http://192.168.100.1 and you can view basic signal information, modem error logs, modem and firmware information. You can use this information and post it on the support forums to get help and diagnose problems. But now that the line and backend bugs have been fixed, everything is running smoothly and I'm saving myself a ton of money (the charge for a new Xfinity modem is $14 plus tax and will be $15 by early 2020 , so pay a bit more for the modem years) each year and you'll have the latest technology, which is even better than the Xfinity modems and gateways, many of which use the aforementioned Puma 6 chipset (which introduces serious delays and timeouts that can kill online play (games or watch videos). So I pay $69.99 and get gigabit speeds of 950Mbps downstream and 48Mbps downstream, which is very convenient, and you won't find these cheap speeds ANYWHERE! The Arris brand keeps the Motorola spirit alive, which is great for the competition! The Arris SB8200 is the best modem your money can buy right now, and if you can find a refurbished one from Revain, even better (they didn't have a modem when I bought mine, but three weeks later they were $100 cheaper) . !
