## Description

desertcart.com: Netgear Nighthawk CM1100 DOCSIS 3.1 Cable Modem (Renewed) : Electronics

Review: Great modem for 1gig cable internet - My previous modem went out after years of use, so in a pinch I ran out to the local brick-and-mortar and bought the cheapest Netgear DOCSIS 3.0 modem, which is good for around 600 Mbps download. That was fine as I only had 300 Mbps service, and it gave me about 340 Mbps download. Well, fiber is moving into my area, so the cable company is feeling the heat and bumped me up to 1,000 Mbps (1 Gig) download for no extra cost. That 3.0 modem maxed out around 540 Mbps. So I decided to spend the money and get a 1 Gig DOCSIS 3.1 modem to take full advantage of the speed. The cost of those are 3-4x more, but then I ran across this refurbished Netgear model for $99 here on desertcart, only double the cost. A modem works in the background and connects you to the internet. It doesn't need to look pretty, doesn't matter if it is new, used, or refurbished, as long as it works. I purchased this refurbished model, desertcart got it to me in a couple days, I connected it and I called my cable company to give them the MAC address, and it has been working great since. I typically get 920-924 Mbps down and 53-54 Mbps up. (photo shows a time I got 62 Mbps up, but it only happened that one time). I use this with a NetGear RAX120 wireless router, which supports port aggregation. I recently connected it this way (with 2 ethernet cables between the modem and router) to see if I would get faster download speeds. Well, it won't give any faster speed from the cable provider to the modem, so the benchmark as pictured remains the same, but may help when several people in the family are downloading/streaming at once. Nice to know this modem supports port aggregation and could run at 2 Gig speeds if my cable provider offers that in the future. But downloads are incredibly fast at 1 Gig -- I am very happy with my purchase and to get the same product at a drastically reduced cost buying refurbished here on desertcart.
Review: Works great, quicker download speed than expected. - I've used this just one week so far. It works great and was easy to setup. I'm happy to have bought the refurbished unit and saved $.

## Questions & Answers

**Q: What is the difference between cm1000 vs. cm1100?**
A: The CM1000 has one Ethernet port that supports speeds up to 1 Gbps. The CM1100 has 2 Ethernet ports that support speeds up to 2 Gbps with the use of Link Aggregation.  Do not let the 2 Ethernet ports on the CM1100 fool you. They are for aggregation use only, not for two separate devices. You will still need a router for both of these modems.

**Q: Does this work will all Optimum services?**
A: I use it with 200mbps plan. I’m sure it works with other plans as well.

**Q: Does it work with suddenlink?**
A: Not if its satellite. Check specifications of internet provider.

**Q: What is the password for this?**
A: the default is name admin /  password is password

### ⭐⭐⭐⭐⭐ Strong Reliable Renewed Cable Modem
*by T***Z on November 28, 2023*

I was a little apprehensive about ordering a renewed modem, and the apprehension disappeared once I received it and installed it. I used to be an avid fan of a different brand of modem, again I was and am pleasantly surprised and not only the quality, but he easy use interface to get this setup with my desired settings just right. Netgear has been around for quite some time and they have always been a dependable and reliable source of networking equipment, it's nice to see they haven't lost their touch.
