Nighthawk

Super fast, steady and reliable. it is a larger unit, but has pivotal antennas, which makes it easy to fit in smaller places.

Pretty good modem/router combo

I got a message from Xfinity about a year ago saying I should upgrade my router/modem to achieve faster speeds and better service. After attempting an upgrade to one of Xfinity's suggested make/models, I returned to my Netgear Nighthawk X4S because it was more stable, reliable, and faster than the suggested

Xfinity Users Beware!

No Xfinity user should purchase this unit. There are numerous postings on the web about this cable modem router dropping WiFi on a regular basis. This requires a reboot each time to get WiFi service back. Support from Netgear and Xfinity just point fingers at each other and do nothing to resolve the issue while the consumer suffers..

Great System, First Class Customer Service

This was a replacement for my previous Nighthawk that had issues. Customer Service was second to none at a quick replacement and no hassle return. System works incredibly.

Insanely bad

Upgraded my speeds to a package that required a 3.1 modem and decided to spend a lot on this device. From the start it never worked correctly, I never got the speeds I should have. A month or two in it quit working completely so I plugged in my older device to get back online. I got busy and by the time I got around to trying to troubleshoot it netgear won't support me past 90 days and best buy won't take it back so now I have a $350 paper weight that I should have returned immediately. And yes I know how to use the device, I work for as ISP and the replacement I just purchased from another brand for less $ works perfectly.

Great Router Until It Auto Loaded Firmware

Router worked great until it auto loaded a firmware update then it was rendered useless. Had to sit on the phone with support for 3 hours to convince them that it was a hardware issue in that I was not able to even do a factory reset. I understand the troubleshooting process but not being able to do a simple factory reset is an immediate red flag that there is an underlying hardware problem. It should not take 3 hours to determine that.

Product Support is Terrible!

j j Comcast pushed a firmware update that makes the modem essentially unusable. Many features don't work now (like static address reservation, attached devices, etc., and only certain devices can get an internet connection. Both Comcast Support and Netgear Support blame the other, and neither are willing to understand the problem. Netgear does not allow the owner to change the firmware!! **Be aware that you will be owning a device that can be modified by a third party, and that modification cannot be undone by you**.

Love this box

So our nighthawk is really good. We enjoy the speeds it provides for us, and the fact it was very sensitive enough to noise on our cable line that Comcast needed to replace.

Fantastic modem for higher tier speed

I have been using the C7800 for over a year now with Optimum and have had ZERO issues when it comes to the modem delivering service. Easy to setup, interface is easy to navigate, and delivers on speed both on ethernet and wifi? This is what a modem/router should be.

Still new to it.

So far I like it. There?s some limitations in the settings. Speed is great within my network but my provider governs overall. Coverage is outstanding if mounted on the wall facing inwards centered between two floors. Excellent device. I gave 4 stars due to limited settings.

Great router but needs technical aupport

When working the Nighthawk X4S is tops. My only disappointment is if you are not a techie you must have Netgear Tech support. Mine was handling my entire 7100 square foot home....until I ran in to some signal issues

Garbage

Bought this modem because my previous modem could only support 200mbps. I increased my interenet to 1 gig and purchased this. It's terrible! This modem is worse than my old one! I can hardly stay on a work call longer than 3 minutes before getting knocked off. Internet pages aren't downloading all the way and bf cannot play video games. After an hour on the phone with Netgear customer support, nothing fixed and they hung up on me and closed the case. Thick accent, could understand about 20% of what the gentleman was saying. Called back in, new case created, and better support person but all the same steps I previously did with no resolution again. For $350, this is a waste of money, time and energy.

Works great but keeps failing

It is fast ... when it?s working. BUT this is the second one we have had that stopped working right. It seems very unreliable. Netgear replaced it twice under warranty but i had to pay $29 for shipping each time. It stopped working about 4 months after I got it both times. I had them plugged into a really good surge protector with lan cable surge protection both times. Netgear said an automatic software update may not have loaded right. I am sorry I bought it and wished I had gotten something else. I would very much recommend you look at something else.
