NETGEAR Nighthawk CM1200-100NAS DOCSIS 3.1 Cable Modem

Don't hesitate to buy refurbished items.

The product looks new out-of-the box. It was easy to set-up from a hardware standpoint. Connect the coax cable, connect the ethernet cable, and power. I did a factory reset before attempting to register the device. That's the easy part.

Following the directions provided in the documentation, I connected to the cable company.through a browser. Do read the documents before you start. Well, I tried to connect. It appeared the connection was not stable. After multiple attempts, This process is bona fide stupid on behalf of the cable company. I had to call the cable company to activate and register the modem.

That's an adventure. After struggling with the language barrier, I got it working. It's been reliable so far. It's been less than a month. I'm using an old router and need to upgrade. I will purchase it from this seller.

Prompt shipping and processing. Don't hesitate to buy refurbished items. You'll help save a small piece of the planet and save money in the proces.Read full review

You cannot use the 4 ports, only 1.

Pro-I have 1.2Gbps service so it worked for that.
Con- The 3 extra ports are useless unless you doing a Aggregated setup. I was hoping to use the ports for my WiFi Router, Gaming PC, Xfinity security router, and my server. You cannot as it doesn't have DHCP. Read full review

Netgear Nighthawk 3.1 the best ever !!!

Netgear Nighthawk 3.1 is the best upgrade ever! Great Price and Fast Delivery.
All my speeds are faster and cleaner.
My previous Netgear Docis 3.0 was only 11 year old, but I suspected I was
getting "throttled" even after I got COX cable Fiber optics installed in my area.
The price of this Modem saved me $1,000's as the Cable companies are attempting to
make you PAY More and act like Lying Telemarketers.(Beware)
I am so happy I got this device and my signals are better and clearer and I do Radio talk shows and media on Dar Outpost with David Zublick.Read full review

The missing stand proved to be no problem. I was able to access the MAC number in the modem and used the stand off of my dead CM1100 so I now have a fully functional standby modem. Thank you for putting this modem on eBay instead of throwing it away! Read full review

Authorizing refurb products

Product works great. This modem was refurbished. It works fine but the original owner info was not cleared which made registration with my internet provider a problem. The internet provider authorized the modem in my name anyway. This could have been a real problem.Read full review

High Performance cable modem, which is ideal for high intensive gaming.

Outside of my having to call my cable provider (Spectrum), it was very easy to setup from their end, w/no issues of any kind.

According to my research, the Netgear CM1200 was a highly rated modem.

After two weeks of using it, I've had no issues of any kind w/it, including playing the game Star Citizen, which is a highly intensive game due to its awesome graphics.Read full review

If you have Optimum check with before you buy.

I believe this product is really good. My problem is not the product, but my cable company. When I tried to get it set up they couldn't get it to read the mac address. They (I believe) had to have someone with more knowledge to get it set up. That was two weeks ago and I haven't heard back from them. Luckily there are two more cable companies moving into the area and hopefully one them will work with this modem. That is the reason I couldn't answer the question does it perform well. I have other Netgear items and they all work really wellRead full review

So Far so Good

This replaced a deteriorating Netgear CM1100 ( download speed drops from over 400mbps to less than 30mbps minutes after a reset). This CM1200 has been holding the over 400 mbps speed for over a week now, the question really is how long will this modem last, the old CM1100 modem lasted for well over 5 years.Read full review
