Title: Almost 1 year later!
Review: I ordered this back on October 4, 2023, its now September 1, 2024 so its been almost a year. I was a bit skeptical about how well this would do given some of the negative reviews and the fact that I bought it as a 'renewed' item. I replaced my old Arris Surfboard Docsis 3.0 modem and let me tell you this thing doubled my internet speeds. Its been a workhorse since then. The setup is super easy and it kinda just sets itself up for you. I've had to power cycle this thing several times whenever I see super slow speeds or Netflix isn't loading. Its the whole turn it off and back on again and that's the only thing I've ever had to do to fix any issues with speed. The last time I had to reboot it was probably over a month ago. I can't recommend this enough to anyone wanting to get a discounted, high quality item!

Title: Works Well! Easy to Insall!
Review: Our cable company said we needed to upgrade so we would get the speeds at home that we were paying for. Rather than renting a modem, we bought this one. It has done the job. It was easy to install and a quick set up after calling the cable company. I like that we can still have our own separate Wifi network.

Title: Arrived in excellent condition
Review: This modern came and I was blown away at the condition of it. Worked flawlessly for me. Hooked it up, scanned it with my xfinity app, and was online with 900mbps download in under 10 minutes. Has been stable ever since.

Title: Just didn't work.
Review: What a hassle.. Arrived pretty quickly, and from surface appeared new.. Went through Xfinity app, and tried to add new device.. Nope.. An hour later still wouldn't connect.. Spent another half an hour dancing through Xfinity maze trying to not connect me with a real person. Finally got an agent to call me back, and spent another hour trying to add this device to their network. NOPE. Said screw it.. Simply put my old modem back on the network, and took about 2 mins to connect.. Got around next day to take return back to Kohls, and what a joke.. Another 30 minutes waiting in line, just to give this back . Seriously not impressed.. I really don't like negative reviews, but this one warrants it.. I have used Netgear many times and think they have good quality.. whomever gets this once it gets back, watch out.. Frustration awaits..

Title: Nice for a Refurbished modem - worth the money
Review: My main dislike was that it only came with a simple setup manual of only a couple pages that was next to useless. Once I got my input cable repaired (broke it removing my old modem) and hooked up the CM1000v2, It kept re-booting and re-booting (they said it would do this several times in the setup) and still it would not find my internet provider's signal (COX and I've been a customer nigh on 20 years), I used my phone and downloaded the full manual. After reading through that, I did what the little included pages did not say, especially since this was a re-furb. I connected my computer to the modem and logged on to it. Did a "Factory Reset" you can do this with a recessed button and I highly recommend doing that as soon as you get it. It still didn't find the signals, but instead of waiting until the proper light stayed lit as the book said, I called COX's tech service (using a different provider and if you had DOCSIS 3.1my old one was 3.0, this may work differently) I gave them the serial# and MAC address of the modem. They set me up there and told me it would take 20 minutes or more for this modem to find all the channels and begin working. Be patient, the tech was right. Took almost 50 minutes, but finally it was on line and wow what a difference it makes over the old CISCO (DOCSIS 3.0) modem I had been using for over 5 years without ever turning it off. Now, we'll see how well this re-furb stands up to 24/7 continuous operation and I may revise my review at a later date if it stops working, but for right now, I love it.

Title: Perfect modem
Review: The modem was so easy to set up on the Xfinity network. I use the modem with my eero 6+ devices. It provides perfect Wi-Fi speeds and fast connection. It’s a reliable modem that doesn’t require restarts. I recommend buying this product so you can save money paying the big cable companies to renter devices.

Title: Quick Speeds and Easy Use
Review: Setting up this modem was a decently hassle-free process that left me better off at the end. This was part of my upgrade from Xfinity’s old gateway and I don’t regret a single penny I spent on it. Its speeds are quick and it is compatible with Xfinity.I recommend this modem.

Review: My ISP has a more nuanced choice than the "suitable for Cogeco" It is not good for my area and has to be returned. Not a manufacturers problem.

Review: Mein Netzbetreiber teilte mir mit, dass ich das Gerät an meinem netz nicht zum laufen bringen werde (techniker hat es nicht geschafft). Daraufhin wollte ich das Gerät natürlich zurücksenden - allerdings war das nicht moglich, da ich in den Rücksendeoptionen nur ein ungültiges retourenettiket erhielt.
