Todd J. Kurzbard –
This is a review of NETGEAR Nighthawk AC1900 WiFi Cable Modem Router with 2-Voice Lines for XFINITY (C7100V).
I have Comcast Blast internet service that typically got me ~150Mbps (measured using speedtest.net). However, I still found that browsing the web (even using WIRED connections) was TEDIOUS – with each new page typically taking 2-4 seconds to fully paint – who’s got time for that?! I got to just assuming that that performance was as good as it was going to get in 2017 (“zzzzzzzzzzzz”), and when I ordered this modem, it honestly never occurred to me that it would improve the performance of my web experience on WIRED connections.
Boy, was I wrong. As soon as I had this modem up-and-running, the difference was immediately clear. Web pages now pop up just like they do in the TV adverts – immediately! This will change my (so-called) life, and I already find myself delving deeper into websites because I’m not subconsciously dreading the slow painting with each new click.
Speedtest.net is now showing 280+ downloads, but the difference in browsing performance seems proportionately much quicker than that figure would suggest versus the previous 150.
Wi-fi signals seem commensurately faster, and certainly have range enough for my medium-sized two-story house (with the modem in one corner of the house).
The installation was a breeze. DON’T CALL COMCAST – I just went to xfinity.com/activate and with 2 clicks and a restart I was up and running (internet and phone service) – almost unbelievable!
The router administration utility is well designed – easy to navigate, and seems to have all the capabilities that I (a fairly technical user) might need.
Of course this box isn’t cheap, but with the new speed I feel like I’ve jumped 5 years + into the future. So that’s worth $300 to me – especially since I’ll recoup that in Comcast rental fees after 30 months!
Addendum – Everything is still working fine, however I discovered that the Comcast ‘Stream TV’ service would not work – their system thought I was NOT on my home network, so wouldn’t show some of the TV Channels. So I had to call Comcast (Yuck!) and wasted an hour of my life telling them that they needed to register the MAC addresses. After they finally did that, it worked. So the web might not suck any more, but Comcast still does :).
So far has made a BIG difference over theComcast modem\router. My WWE network on ROKU (which had CONSTANT, ABSOLUTEY INTOLERABLE buffering making it UNWATCHABLE) has only buffered ONCE (the one buffering hs left me VERY disappointed, but I’m hoping it’s a one-time thing), and worked perfectly since I installed this modem\router. Picture on the WWE Network is perfect as well (was pretty good, but VERY “iffy” with the Comcast modem). Internet speeds (I have the Comcast 150 Mbps – which I will probably be lowering now to 100 to save money) hit 180 Mbps repeatedly on one speed-testing site.
Yes, this modem\router is very expensive, but it was worth it to me (I like to buy ONLY the best, and am willing to spend the extra $$$ for it), and it will pay for itself in 2 years.
The ONE thing I will caution potential purchasers – if you have Comcast, CALL COMCAST FIRST AND HAVE THEM ADD AND REGISTER THE MODEM\ROUTER BEFORE YOU SET IT UP – I went through 2 hours of pain and suffering because it wouldn’t set up since I didn’t do it right – it knocked off my phone and internet, so I had to reattach the old Comcast modem to get my phone back to add\register the modem\router. That got back my phone on the new modem, but THEN EVERY web page went to a Comcast registration\activation page, asking for a code. Comcast wouldn’t give me athe code, and told me to call Netgear, as it was a Netgear problem. Netgear told me it was a COMCAST problem. Back to Comcast, who kept redirecting to the wrong departments. How I FINALLY got this to work was to activate it under ‘other methods’ (shown as a little ‘link’ under the code input box). It will ask you for some other activation choices, such as ‘address’ – I think that as the one I used – and once that was done, I had full internet.
So this works GREAT if you know what you’re doing when you set it up. Follow my advice for setup with Comcast, and you should have FAR less problems then >>> I <<< had.

Our ISP sent out four teams over three weeks to permit our HP wireless printers to recognize the Internet . The last visit had two techs and a supervisor. After two hours they came up with cockamamie way for my wife’s wireless printer to function. I couldn’t figure it out after they left so she had to rely on the irregular and unreliable use of my wireless printer. Mine had to be turned off then on daily and would print literally hours after I selected the printer command. Makes it impossible to handle business need and after two months I cannot speak with decent words describing my feelings.
A HP supervisor told me, “I can’t say this officially but XX is like most ISPs: they offer a mass-produced poor-quality modem/router and we get calls endlessly seeking help for our customers to access the Internet for their printers.” She recommended NETGEAR.
When the last XX crew came out I told the supervisor about HP’s claim and he was HIGHLY defensive. Claimed his is equal to if not better than any NETGEAR model/router. A week later I purchased NETGEAR and seconds after I hooked it up I discovered how wrong he was. After two months of aggravation finally both printers are working. I wrote the CEO of XX and he had someone contact me last week regarding the situation. I explained my experience but haven’t heard anything since. I am not compensated for this review or this recommendation but we purchased the Nighthawk AC1900 Modem Router (C7000) and highly recommend it. It was simple for this 69-year old computer nerd to set up and our Internet access never waivers and our wireless printers function just as they are designed. The Nighthawk works great for us. I assume it will work well for you as well.
I bought this modem because I pay for top tier internet and cable through comcast and I wasn’t getting the proper speeds that I was paying for with the comcast modem. I have seen a lot of reviews about dropped wifi, incompatibility with comcast services (mostly voip which no non-comcast modem that I’ve come across is actually capable of), and issues with the router being faulty in some way. I’ve never really had any dropped service, wifi works great, I get the speeds I pay for (sometimes better speeds) and short of power outages it hasn’t ever cycled on me. I have several devices connected to it at all times (smart home speakers, tv’s, gaming consoles, computers, phones etc) and everything works the way it should with no real issues. I love this thing. I’m happy with my purchase and it’s been about 6 months or so since I purchased it. I waited to write my review to see how it performed and I couldn’t be happier.

This is a combo modem/wireless router and it is fast! I wanted to stop paying that notorious $10 per month fee for “modem rental” and buy my own that had my own specs. I could have bought them separate, and that’s what a lot of people do, and I might eventually do it after having this for a while. But with this combo one, you get the benefit of an awesome modem AND a Nighthawk wireless router. I doesnt have antennae, but it covers my apartment just fine. I thought long and hard about this one and spent hours on my decision, but you’re getting an awesome modem, combined with the AC1900 Nighthawk router!! I got this at 8pm at night, and did not even have to call comcast to switch it out. The instructions take you step by step, and Comcast recognizes the modem, so I pretty sure I just had to login and do a few things which are outlined in the instructions, and it switched it out! I was so surprised! I thought it would take MUCH more than that! And it has the channel bonding which takes 28 channels and turns them into 8. So I have the fastest internet in the building BY FAR. If you want fast, easy, and no cable company hassle, get this. It is worth every penny, and youll make it back, because I was paying $10/month for the modem/router. I was concerned about anyroom DVR and stuff, but that done through the coax cable, not the internet. This is legitimately FAST plug and play. And look how little room it takes in the pic, it’s really small!
