Works with Comcast new 1 gig service, faulty cable

I was be able to register the modem automatically just following the webpage from Comcast after power up. We also have a roku we use for the second TV and that works also. My account shows the modem as disconnected but it works. I guess during the week I call them up and see if all is ok and their end. The only negative is the cat5e cable that was in the box fit only give me a 100 connection to my desktop and not the 1000. Took me a moment to figure out that the cable was at fault. I used a cable that I have laying around and got a full speed right away. Looks like the cable from Arris is defective. Should you not get the 1 gig speed you should check if you have a 1000 connection established to the modem.

A must for Gigabit speed

Been using several Arris modems for years, they are of great quality, though would be great have they are build of better plastic and have black color too. If you have Gigabit speed internet, SB8200 or and modem with DOCSIS 3.1 is a must, otherwise, your ISP may not like it and you may not get the speed worth. This modem squeeze out as much as it can from my ISP and speed is great even during high traffic hours. Make sure to check with your ISP that the modem is compatible with your Gigabit speed. If you have anything else lower, this modem is unnecessary overkill unless you want a future proof product.

Solid upgrade from DOCSIS 3.0 16X4

The SB8200 DOCSIS 3.1 32x8 modem is a solid upgrade on older 3.0/16x4 models - with more channels bonded, you have a better chance of maintaining full bandwidth even with a neighborhood full of users online. And stepping forward to 3.1 is the only way to enable "gigabit class" internet from your ISP. Even without the gigabit package my 400mbps (down) connection went from 350-370 down with my older modem to 440-450 down with this, a great upgrade. Installation and activation was also fairly easy, though I did have to call my provider to get them to remove my old modem's MAC address from their registry and replace it with this one. So far it seems stable and fast. Now, the downsides...well, there aren't many. For one, it does get a bit warm in operation. Not worryingly so, but worth noting. I suppose the biggest gotcha here is that it claims "10Gbps" downloads. And while the modem may be capable of that, anything downstream will not be, since the modem has but 2 gigabit Ethernet ports that together would max at 2Gbps. Not a huge deal since no provider offers anything close to 10 today, but worth noting for the future. That said, most competitors offer only 1 gigabit port and so would be even more limited.

Deceptive marketing aside, this is the go-to modem for DOCSIS 3.1

While modems like the SB6190 state that they can provide up to 1.4Gbps, most ISPs require DOCSIS 3.1 for their gigabit packages. My ISP (RCN) is one of them. Swapping the modem took no work and it immediately registered on DOCSIS 3.1. The modem connects directly to an Asus RT-AC68R and my PC is hardwired directly to the router. 900+ down hardwired, 550 down on 5G, and 190 down on 2.4G (wireless speeds measured using an Asus PCE-AC68 wireless card). Ping times are around 9-15ms across all connections. The issue I have with the deceptive marketing is that this modem is advertised as a "10Gbps Max Speed" modem. This is technically correct because 10Gbps is the spec for DOCSIS 3.1 and this modem could receive a 10 Gbps down/up connection to and from your ISP. However, both ethernet ports on the modem are gigabit. Even with proper link aggregation, the fastest down/up speed you could ever see with this modem is 2 Gbps. As a consumer, I have yet to find a reason to go beyond gigabit. Even if I did, I would likely opt for a fiber connection for to reduce latency.

Arris product support is fantastic.

When the modem we had started acting up and was deemed no longer approved for use with timewarner/spectrum, i ordered this Arris product. When the order arrived on Sunday I immediately set it up and called for TWC to connect the modem, they could not make it connect, including being connected to a higher tier "tech". In the packaging was a notice from Arris to not return the modem, but call them. I did. Sunday afternoon when most offices are closed, the tech at Arris confirmed the modem was fine the connection was not. I cannot say enough about Arris customer support. If your Arris product does not work, call the number on top notice in the packing first. While TimeWarner/Spectrum could not fix it and had to schedule a visit from a tech 24 hours later who made a call and added the modem to the account which was not done. Bad marks for TimeWaner/Spectrum, Great marks for Arris.

Easy Install

Needed a Comcast approved modem that would work at 100 mb/s and higher. Was able to switch out the other modem which I also owned and get this working without a phone call to Comcast. Just know that the second ethernet port is not active, as Comcast only provides one IP unless you purchase a second IP before using.

Docsis 3.1 latest Texhnology pros and cons right here...

The product arrived in a very nice box. Split case glossy package that was well formed to protect the product and of course attractive. Upon separating both halves and opening there say what appeared to look identical to my previous model however it is not. Upon closer inspection this is the new Docsis 3.1 well raved about online. You will first notice two gigabit ports. This is where the Con is and it also applies to every other brand D-3.1 modem on the market with multiple E-net ports. You may only choose one. Attempting to use two will cause ISP confusion and your devices will not function properly. You would need your provider to assign another ISP address to the second port and some may or may not opt for this feature or may charge an additional $10/mo fee. Since it is also not wireless you will need to provide your own wireless router and any sub Ethernet network ports if you choose to multiply incoming/outgoing connections. The Pros are obvious this beast is insanely fast. Even with my iPhone I am getting 500mb/s download speeds and 40 mb/s upload speeds which is a hardware limitation at my end although it is ridiculously fast compared to most people’s standard home hardware. These speeds eliminate all buffering issues with streaming, and allow ultra fast downloading of very large files for you IT guys. For the price I recommend the Arris SB8620 and if your service offers higher speeds to consider using this model even for 250, or 400 mb/s speeds it will be more true to those speeds than its predecessor SB6190.

Fantastic..Most Spectrum's Tech's suck!!!!

This is the second one I tried. First one. No Luck. Then @2AM Sunday morning tried again. (11/1/2018. Called and asked to activate my modem. Gave the tech MAC address and nothing. he transferred me to Tech support. They said they cannot help because it is my equipment! Anyhow, after multiple phone calls I gave up. Reconnected my old modem and it came right back on. Made me think, ? How in the hell can they activate a modem when they did not disconnect the old one? So I called back and now it's getting to be after 6AM. I got a really young Tech and explained what was going on and she agreed. She said wait a min and after a few seconds she asked me for my new Mac address and within seconds it was up and running!!! She said she was sorry for the runaround they did not know what they were doing. It is rock solid and I am getting 540M down and 32M up. God bless the tech and Amazon for selling an excellent unit.

Nice Internet Modem to replace your cable company's rental modem

Awesome cable modem that eliminates the monthly rental charges that cable companies live for. Capable of a download speeds up to 686MB. Has plenty of status lights on front to tell you what is happening at the moment. Can log into the unit to determine packet loss, errors and channel status. This is a simple modem that does its job well. If you are paying Comcast, WOW!, Xfinity, or another company a monthly fee then this is the unit for you. Simple to setup. Just screw the coax into the coax connector, plug in the LAN cable for your router, and plug in the power cord. Then call your cable company and tell them you bought your own modem. They will ask you for the MAC id number on the bottom of the modem and then they will authorize it to work with their network. That's it and you are up and running. PROS: - Nice price - Super easy to setup - Saves you on monthly rental fees from your cable company - Can support download speeds up to 686MB - DOCSIS 3.0 for 16 Channels Down / 4 Channels Up CONS: - None

Uses new DOCSIS 3.1 technology

It was easy to install and activate (Comcast). But interestingly as per the front panel LED status my modem is "receiving" using the DOCSIS 3.1 technology but sending using the backwards compatible DOCSIS 3.0 technology. I don't believe that's the fault of the modem. I believe that it's the ISP that's causing this problem so I'll have to call them to find out why. And other than that there have been no glitches or dropped wifi. Also it comes with a quick start guide with a web address so you can register the product. After registering mine it said the warrantee was good until November of 2020. The booklet also provides a phone number should you require technical support. Overall I upgraded to this modem because for the last couple of years I was using an Arris SB 6141 which was extremely reliable and had experienced no problems with it. So as a result I stuck with the same manufacturer.
