Netgear Gigabit Cable Modem (32x8) DOCSIS 3.1 | for XFINITY by Comcast, Cox. Compatible with Gig-Speed from Xfinity - CM1000-1AZNAS (Renewed)

Works great no problem and was packed really well. It came in perfect condition for a refurbished item. Recommend this seller. The only thing negative is it took a lot longer to get than I wanted but it was still in the estimated time frame. It was roughly 3 weeks after ordering to delivery. But it was work it overall.

Cable has been acting up for a couple of weeks and I noticed the modem's light were flashing differently and intermittently. Ordered the modem and it came the SAME DAY!!! I just used the same power cord and Ethernet cable for the new modem. It took all of one minute. Turned it on and waited for all the 4 lights to turn green and the bottom one to turn amber. It took about 20 minutes.It did keep on resetting, but that was expected. Called Xfinity with the new MAC#. They reset everything. I then reset the router and I was back in business. Total time from beginning to end (including waiting on the phone with Xfinity) about an hour and a half. Now I have a good connection and the speed of the internet seems super fast now. The old modem was installed in 2017. I am extremely happy with purchase.

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!

UPDATE after 8 Months ---------------------------- I've used this modem for about 8 months so far and for the most part it's been okay. My only issue is that it drops connection about once a month and will stay that way until I perform a reboot. This started happening a few months ago. To reconnect, I unplug the modem for a minute, then plug it back in. After that, it stays connected for about another month. If this becomes more frequent, I will consider switching to another modem. ORIGINAL Post ------------------ I recently moved and found out, much to my dismay, that Comcast is my only hi-speed internet option. I refuse to pay them any more that I have to, so buying my own modem was a must. This modem was reasonably priced compared to other brands and met the specs I needed. Installation was easy enough, but came with very little documentation. I am a full time IT engineer, but I think most people should be able to set this up without a problem. Once connected, I tested the speed and it performed well. I have an 800 mhz plan and got speeds exceeding that. My only wish is that it had more than a single ethernet port on the back. I have an Eero mesh router which has to use that port, so I have to plug in my ethernet switch into the Eero mesh instead of directly into the modem. This makes connecting to the modem's setup screens a bit of a pain. I am very happy with this purchase though.

I tried 2 of these. First one I could tell wasn't working correctly, it powered on but it didn't go through the back-and-forth with comcast to connect. I couldn't even see the device by it's address on my network. Eventually I got through to Comcast and they pushed a connect signal - nothing. Did a factory reset and this time they got a signal to it where it gave the "activation" instructions but they still couldn't get it to come online. 2nd one - definitely different. Did the back-and-forth and all that, but still couldn't see it on the network. Factory reset and there it was, and I got the Comcast activation message, too. It was gonna' work....... and after over a half-hour of multiple activation signals, alas, it's still shows offline at Comcast. There customer support - it's there a couple hours a day Eastern time - if you're anywhere else try around 11 - noon your time. Amazon - time to get a new refurbisher - just making sure it's clean and has parts and powers on isn't enough, you know darn well I'm going to Best Buy this time. Oh, and just in case you're wondering if I actually can't properly plug in and connect a cable - put the old modem back in and 5 mins later I'm writing this review. DO NOT use a device from Kanga. Not just ZERO stars, negative stars. TERRIBLE.

Awesome. I can’t tell it was refurbished all. Looks and runs like a new one too me

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.

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.
