ARRIS (SB8200-RB) - Cable Modem - Fast DOCSIS 3.1 32x8 Gigabit Cable Modem , Approved for Comcast Xfinity, Cox, Charter Spectrum, & more | 1 Gbps Max Internet Speed, 4 OFDM Channels - Renewed

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.

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.

My old Surfboard modem was failing, so I chose this renewed modem to replace it. That's when the real fun started! I installed it, registered it with Comcast and everything seemed ok at first, but then (although according to the modem lights it had an internet connection) I had to power cycle it. This kept happening, so I thought that perhaps the internet port on my (older) router had failed, so I replaced the router (with a mesh router - that's the only silver lining to this tale of woe!). Still the internet connection won't hold. I'm wfh mind you, so now heavily depending on my cellphone's hotspot :(. I call Comcast and they say my modem "looks healthy", so they send someone out to look at all other external connections and they replace the wall connector as well as an outside splitter. While doing this they manage to disconnect part of my Dish TV, so now I have to have Dish come out to reconnect. Still won't hold an internet connection. So I go buy a new (Netgear) modem, install it and I haven't had a drop since. Mind you, this took place over a 3 week period - what a PITA - I've left out all the calls, sitting on hold, online working sessions with techs, online research, overall confusion, and major inconvenience experienced. No refund compensates for all of that frustration and lost time. Moral of the Story: Stay away from renewed electronics if your livelihood depends on them! Or if you just don't want to suffer the major inconveniences that may come your way.

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 bonus worth the $99 I paid for it and I am ready for when docsis 3.1 happens The 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
