  • Pretty awesome equipment.
I love this router/modem combo. I typically don’t like equipment that is shared but this one that has met my expectations. The signal quality is great and reaches all the way through my place. Additionally, as for compatibility, both the 2.4 and 5 GHz channels work well with all of my equipment and I’ve had no issues connecting anything. And finally, the speed is off the charts… Whenever I go to check my connection speed, then I have no issues and actually maxed out the charts. ... show more

  • Avoid at all costs, they don't last even a year!
The unit arrived and set up was relatively straightforward however there were several configuration changes that only Netgear support could figure out so after all that, it worked well for 9 months. Then it died. I mean lights are on but won't connect to the Internet, Wi-Fi is not working. I tried rebooting, a full factory reset but nothing worked. Contacted my cable company to see if they could ping it based on mac address but as suspected, it didn't reply. Moving on, I checked on my warranty status and discovered it only had 6 months coverage. After that either you pay for their extended warranty or you're out of luck. I'm one of those. Don't throw away $300+ on this item. It doesn't last and a company that only offers 6 months of warranty out of the box knows it! ... show more

  • Setup is a pain!
Order was shipped but got damaged and was returned by USPS. Re-order was shipped with no issues. Router/wifi was a pain to setup. They(netgear) forces you to download their app and get their Netgear Armor to finish setup. If there is another way I didn't find it. Otherwise it's up and working fine. The seller of course has nothing to do with the setup or function of the product. Be prepared to spend some time setting up and dealing with the Armor crap. ... show more

  • Difficult Install... but
Oh my, the setup was not fun. Devices couldn't connect no matter if I rebooted the device or modem. After a few days the problem seemed to stop. I have no issues now. Be aware that the instructions given isn't actually what happens. For instance, I have Comcast. The instructions given a basic walkthrough but aren't accurate. Luckily I'm somewhat familiar with setting up networks. Another issue that I did need the app to complete something's that could've been done via PC. And something's that I tried to access the router via the PC...I got no response. I still have some common devices that cannot connect to my guest network. The good: my speed is faster, and the app is cool ... show more

  • Working great
It's been up and running about two weeks now. Except for one reboot it's been working none stop with out an issue. The speed of my network is so much better now. Although my ISP reported really good network speeds I was getting dumped off my WiFi quite often with their modem. This has me on WiFi as much as I want to without fail. Great product to work with, easy to set up and use. The app has alot more detailed information than my last router app did. Also, the support team is great as well. They answered my questions and gave me good advice on how to set up other options I didn't even know I had. Great product, people and service. ... show more

  • Beware of buying used
Let me start by stating I am not reviewing the actual product, but the Amazon Renewed program. Bought this from said program. Thought it would be nice to be environmentally friendly and save a bit over $100 in the process. The router came in a beat up looking box. No padding other than one single piece of bubble wrap, wrapped only once around. It was obviously abused in transit. The device looked okay but very scuffed. No instructions, just a thank you message from the program. I figured as long as it works, I don’t mind. Well, it did not work. It would turn on, but it would never register and activate with Xfinity for some reason. The Xfinity technician could not male it work either after trying several times. Returned it immediately. Beware of buying from this program. It is a risk. They include a phone number to call them if you have a bad experience, but who wants to talk to service agents when being so frustrated and wasting a whole afternoon already talking to technical support. Too bad really. ... show more

  • Had some initial hiccups but ultimately figured it out
I understand it's a refurbished product and knew the risk of the Gamble I was playing. It turned out to be in great shape. Almost brand new. But there were no LAN cables or instructions in the box. Just the router and power brick. The most difficult hurdle I faced is the router didn't come factory reset. The person who used it or the previous owners information were in the router. So while I could connect to the WiFi, but couldn't access the admin interface to setup the wifi as I would want to. The default admin/password combo didn't work. Had to use the reset button on the back multiple times to reset it. It didn't reset for the first few attempts. Tried with coaxial cable on and off both. The 5th attempt without coaxial cable connected seemed to do to the trick. I had to press the reset button on the back for 7-10 seconds and the router was successfully reset. I was able to set-up the router with the admin web interface 192.168.1.1. But you can also use the Nighthawk router app to set it up. Next was calling my ISP which is optimum in NYC, and ask them to activate my modem. I gave optimum the MAC address of this device, which is printed on the bottom, and it took them 15 minutes to activate it. After that it's been a breeze! I'm using the 1 gig package. Getting 980 Mbps download via wired. I could rate the product 3/4 star for the initial hiccups, but hey I am a tech savvy person and buying a refurbished product, these issues sometimes comes to haunt us. I hope this review helps if anyone else wants to purchase it in future and faces this same issue I faced. Among the other reviews mentioned for this product where the signal dropping off, router restarting randomly or losing connection, I'm not facing any of the above. So far pleasant experience. Goodbye router rentals!!!! ... show more
