Good while it lasts.

Worked great for exactly 3 years. I wonder sometimes if items like this has a built in ticking time bomb to just go after a certain time. Worked well with the Netgear AX5400 Nighthawk. But I'm skeptical wondering if that doesn't go next cause I got that a month later. LOL.

Great refurbished modem

I was looking for an affordable modem and took a chance on a used one. So far so good. Just like a new one!

Excellent fast modem

This is a great modem. Buying this modem outright will save you money on your cable bill over time. This modem is a lot faster than the old one I had and can keep up with the speed of modern internet connections. It does not drop the signal and works perfectly. It is easy to set up. I use this modem on Spectrum and it is officially on their compatibility list.

Netgear/Orbi solid performance

Recent upgrade to a Orbi 8 system and our previous modem could not handle it so we installed the netgear 3.1, modem is super fast and it a perfect match with the new Orbi system.

Works well

I bought it at Best Buy. My old netgear modem wouldn't support my higher speed internet. This one was easy to set up, but it took Spectrum a little extra time and effort to connect.

Netgear Gigabit Cable Modem

The best part of my Netgear Gigabit Cable Modem is the technical support I received over the phone when I encountered problems during installation. The problem ended up not being with the Netgear Modem, rather I needed to contact Xfinity to get the new modem registered on their system.

Overall worked well decent price

Bought after our cable company said the one we had through them was not working. It was going to take two weeks for them to send us a new one! Due to me being a student I needed it asap. Went to Walmart and picked this one up. Plugged it in and set it up. Had no issues! A lot cheaper than the one from the cable/internet company we use too!

Replaced the Cox Cisco modem I was renting. NETGEAR modem is working as it should. Waiting for a NETGEAR router to pair with. Hopefully my connection speed will increase.

Very Impressive Modem

By Tubbybear1

This modem works like a charm. Very impressed with its performance. Sure like the on-off switch that this model has. I purchased the router from Best Buy so I could go pick it up the same day.

Very helpful customer support

By Chris H.

I bought a new cable modem and installed it myself, but it didn't work so I called customer support and they were very helpful and patient because I'm old and we got it to work
