Solid budget option.
I will admit. I was a bit skeptical to try this as it was likely returned or something like that. I was in a pinch and had to replace my modem quick the next day and this was all Amazon got for next day delivery. It arrived and setup was easy to get going. It definitely had been opened but what do you expect for renewed. It has operated just fine over the past few months that I have had it. It is super nice to not have to pay a bill every month! The internet has not dropped and the speeds are at or above advertised giving stable and reliable speeds and internet connectivity.

works great with xfinity
Works perfect, I upgraded from a SB6183 that only gave me just over 500mbit and with the SB8200 I get just over 700mbit so a slight bump in speed, my isp xfinity speed package is only 600mbit so I got a slight bonusworth the $99 I paid for it and I am ready for when docsis 3.1 happensThe only CON with the SB8200 is you cant set the LEDs to DIM mode in the modem web interface like you can on the SB6183, you only have on or off

Still overheats — disappointed after upgrade
I replaced my old Arris modem with a newer model to get faster speeds at the suggestion of my ISP. My old modem overheated frequently, and I had to place it on top of a fan to keep it running. I hoped this newer version would have improved cooling, but it seems to have the same problem. It goes down almost daily and needs to be power cycled. Even with a fan, it still feels quite hot when I reboot it. Overall, both models I’ve tried have had similar overheating issues, and this one performs even less reliably.

Looks and works like brand new! Works fine with Optimum Online (Altice) in Northern NJ.
I have Optimum Online (a.k.a. Altice, a.k.a. Cablevision) 500mbps broadband Internet to my home. I keep wanting to switch to Verizon FiOS, but every time I call Optimum to cancel they lower the price of my service. I figure in about 4 more years they’ll be paying me to stay. Lol. Which is okay with me, because as bad as Optimum’s tech support is, Verizon’s billing department is worse. But I digress.The product I received is virtually indistinguishable from new. The modem, the power supply (a 12V/1A wall wart), the box, even the documentation looks factory fresh, without a scratch, smudge or hint of dust. The only giveaway is a small “REFURBISHED” sticker on the back of the modem, and a lithographed “Refurbished Unit” sub-header under the Arris logo on the top of the box. I removed the Optimum-supplied Ubee WiFi gateway, plugged-in the Arris SB8200 and, from my phone, initiated a chat session with Optimum’s tech support to provision the new modem. It took a total of around 30 minutes for the tech to finish provisioning the modem, but then I was up and running with speeds equal or even better than I had before.Two things to note with the SB8200: 1.) it will only communicate with the device plugged-in to the LAN jack when it was rebooted; if you swap devices you need to reboot the modem to get back on the Internet, and 2.) Optimum provides only “best effort” technical support, and no warranty/repair services, for modems purchased from a third party. This applies whether the modem was bought new or refurbished.I wanted to replace the Optimum-supplied Ubee WiFi gateway with simple modem because I run my own firewall (pfSense), switches (TP-Link Omada) and WiFi AP’s (also TP-Link Omada). The Ubee was fine when set in bridge mode (disabling its router/firewall functions) but the Ubee’s (extremely strong!) WiFi radios could not be turned-off, and that was interfering with my own AP’s signals. Plus, by returning Optimum’s gateway and using my own modem I’ll save $10 a month, so this refurbished SB8200 will pay for itself in less than a year.

Get the “refurbished” bargain!
Dont be afraid of “refurbished.” It was clearly brand new in an opened box. It fired right up. I was on the phone with xfinity for about 20 minutes getting it formatted. Works great and internet is crazy fast! You can expect these are being returned because people are A) expecting a modem/router combo or B) they didnt take the time to get it set up with their cable provider.

Great Upgrade – Fixed My Internet Issues with Sparklight
I upgraded my old Arris modem to this newer model since my previous one was outdated, and I’m so glad I did. It works perfectly with my Sparklight internet, and the difference was noticeable right away.Even though it’s a refurbished unit, it looked brand new out of the box—clean, well-packaged, and no signs of wear. The best part? The random internet disconnects I used to deal with are completely gone. My connection has been stable and fast ever since switching to this modem.Overall, it was totally worth the price. If you’re still using an older modem and dealing with unreliable service, this is a solid upgrade. Highly recommend!
