[This review was collected as part of a promotion.] This model of the nighthawk set up quickly. You just need to make sure you get a hold of COMCAST to register your product. Registering can be quick and easy if you use the Comcast net Xfinity app on your cell phone. You can log into your account and register your serial number.
[This review was collected as part of a promotion.] I now have Netgear Xfinity modem, separate Netgear router and a Netgear extender. They replaced Xfinity rental modem/router. No amount of telephone contact could get the Xfinity equiplent to work. Several hours of SMS chat with Xfinity got the Netgear modem working. The router and extender setup with the Nighthawk app was seamless. Speed tests show a dramatic improvement between Xfinity rental equipment and Netgear. I've been paying for 600 mbs for years and never got more than 250 mbs download. With Netgear the measure of download is 700 mbs on the Nighthawk app speed test and 260 on OpenSignal app? I use Opensignal app for speed tests. With Xfinity modem/rounter many apps and devices stopped working. Everything now works. I have the 200 page router PDF user manual on my iPad. I shall go through it to see what I can do with the router. The network disk drive looks interesting. I need to know more about Netgear Armour before I try it. I will look for the documentation. I have Apple iPhones, Ipad, Apple TV, Windows 7 and 10 computers, Android cell phone, Samsung Android A7 tablet and a Sonicdust HDHomerun ATSC 3.0 OTA TV tuner on my home network. All are now working. I could not say this for the Xfinity modem/router.
Two defective units in a row, claimed to be supported by my cable provider but they could never get it activate. If you want a home phone, you're better off doing voice through a VOIP provider and doing internet only if you're in the Optimum service area.
Netgear first claimed they supported this modem for any cable provider and later backpedaled when they couldn't get it to work saying it's only certified for Xfinity. Optimum claims it's officially supported but couldn't get it to work both times claiming the modem was defective.
Setup process was easy with my carrier. I had a separate phone and cable modem, now it's one modem for both. Significant speed upgrade capturing more of the speed from my provider.
