    Ready for faster cable provider Internet plans
    Retains all of the administrator features of previous Netgear cable modems (such as ACL configuration, static IP assignments, blocking MAC addresses, et cetera) which is good. Potential transmission speeds are awesome (2018) and fit well for possible future cable Internet plans with higher bit rates. Has already fit well in one ISP provided Internet Plan upgrade. Works well with Mediacom (use "other MSO" documentation). Note comments about Internet phone service bundling.Takes a little getting used to a flat layout design versus vertical so some additional planning may be needed to decide where to place it - otherwise design has a nice appearance. Antennae are already connected in the delivered unit which is nice. Having DOCSIS 3.1 capability is good for future cable provider service advancements. Of course, DOCSIS 3.0 is also available.To "import" (manually) configurations from a previous Netgear cable modem may be easiest done by taking screen shots of the previous device whilst still in service and using them to configure the new Netgear cable modem. Very handy for large amounts of ACL entries! Better would be if both were active (though not both connected to the cable provider at the same time, of course) with the ability to copy and paste between them.Boost in WiFi output over previous Netgear cable modem/WiFi routers is welcome for devices that are far enough away that they may have had some signal quality issues before. Boost in WiFi bit rate is very much appreciated and improves overall data stream quality and stabilty.

    1.0 out of 5 stars What an upgrade from the Asus 68U router...like wow.
    Reviewed in the United States on April 20, 2018
    This Router/Modem is huge. But thats a good thing. Its large enough for you to slap two 120mm fans on it to keep it ice cold all the time. The status lights are bright. The tips of the antennas light up and the best part is it SOLVED a huge problem I have been having. We have a 1200 square foot home, concrete block btw (Florida) and we FINALLY have full bars on the 5 GHz spectrum, yes 5 ghz. All throughout our house! No more internet drops, not a single connection issue. When it connects it is ROCK solid with you even walking through the house.

    We just got 400 Megabit internet from Spectrum and needed an upgrade and decided to go all iut on this combo. We've only had it for a few days now but I am already super happy the wifi reach war is over. We purchased the Triband Asus router, forget the model to try and solve our reach issue, (I would have netflix disconnect in my room. 20 feet from our router, and the new router was just as terrible as the 68U.

    This nighthawk is no joke though! Highly recommend for a future proof router for a while!

    Update: So we came home from work last week and the router was SYPER slow. I rebooted it. Then factory reset it, did like 4 hours of trouble shooting. The ethernet works fine hard wired when we rested a laptop, but the wifi seems to have pooped out. Even with fans keeping it cool it STILL failed. That should not have happened....considering we paid over 400 dollara for it. Failures like weak wifi and slow wifi speeds just should not happen. We watch youtube, netflix and hulu andnoccasionally play our switch online. We're not heavy users and like I said theres fans on them 24 hours a say.
