Netgear Modem is Trouble Free

I installed my Netgear CM500 (and Netgear router) years ago. Both units are still going and I am very happy with Netgear products.

Frustrating

I was on the phone for over two hours trying to install it because someone had mistyped my email address and I'm still awaiting resolution of the problem.

overheated

It died after 3 months of use. It was probably overheated. Performance dropped and then it won't connect again.

Can't update firmware

It works but I can't update the firmware so it doesn't work at full speeds with spectrum. Why can't we update the firmware for this stupid thing?

Reliable and Efficient Cable Modem for Home Use

I've been using the NETGEAR Cable Modem (16x4) DOCSIS 3.0 (CM500) for a while now, and it has proven to be a reliable and efficient choice for my internet needs. Setup was straightforward, taking just a few minutes, and it works seamlessly with my ISP. The modem supports speeds up to 680 Mbps, which is more than enough for streaming, gaming, and working from home. It handles multiple devices without any noticeable drop in performance. The design is compact and doesn't take up much space, which is a plus. One of the standout features is its compatibility-it works with major ISPs like Xfinity, Spectrum, and Cox. It has saved me money by eliminating the monthly rental fees for a modem. Overall, the NETGEAR CM500 offers great value for its price. If you're looking for a dependable modem that's easy to use and performs well, this is an excellent choice.

Not even a month

Within a month of hooking this up, it refused to work anymore, Netgear refuses a warranty exchange unless I allow them to access remotely first. Will never purchase from them again.

Great After Years of Use

I've had my Netgear modem for over six years now. I've had zero issues with it and that's the first piece of computer equipment I can say that about!

Works Well With Xfinity

I have been using this every day, going on four years, with no issues. It does seem to run a little hot, but again, no issues. The one time I called support with a question, they were less than helpful.

Should have done this long ago.

After years of issues with the Spectrum supplied modem, I finally decided to try a product from a company that specializes in routers and modems. It was a great decision. 90 percent of the constant dropouts I was experiencing have come to an end. I can finally enjoy the internet without interruptions thanks to this inexpensive modem from Netgear!

10 times better than the rented router. Once it's set up you almost forget about it. Seemless sign in every time.

Reliable

Have had this modem since 2020 and it's been so reliable and dependable I hardly think about it! It's provided a consistent high-speed internet connection to the many devices in my home with only the rare power cycle required (my last modem needed nearly daily power cycles). Thanks Netgear!

Great Modem

This modem has been running strong for years without any issues. It is silent and fairly low power consumption in comparison to the newer Comcast branded models. Unfortunately, Comcast appears to throttle the upload speed to 10 Mbps on DOCSIS 3.0 modems, even though they can support such throughput.

When it works, it works.

This was a relatively easy-to-set-up and use modem - it lasted about three years before I had to get rid of it. I'm not sure what caused it to stop working, but it was a shame that it did.

Excellent company

The NETGEAR we purchased was a 2021 model. I had difficulty matching it to my infinity box. I called support they couldn't fix it virtually. They sent a technician out he politely replaced it with a brand new 2023 model. It works perfectly. NETGEAR is A1. I will always be a loyal customer. Outstanding!!

Never worked

I made two attempts to have Xfinity enable the modem. They could not. I called for Netgear support. Extreamly slow and frustrating. I asked repeatedly, and I mean many times, why the upstream and downstream leds were always solid red. The support person refused to answer that question and after a long, long time on the phone, I gave up and hung up. This person appeared to me to have no idea of what he was doing. The Quick Start document says you can see a red light from the power led, but it does not indicate the condition for a red display on either the upstream or downstream leds. I'm back renting a modem from Xfinity and will return the Netgear.
