this device is a beast!Posted .
so glad i finally get to upgrade and get rid of that modem rental fee by my provider. this is my first time owning a router and modem in one. the item is bulky itself but it only makes it more beastly. set up was very user friendly. i spent about 30 minutes but i enjoyed every bit of the install. new tech always excites me. i have approximately 25 devices connected in my house from smartphones, tablets, computers, smart cameras, ps4, smart tvs, smart lighting, smartlocks and wifi sprinkler system so it's crucial i have a good router. i do feel an increase in speed and wifi coverage throughout my 3 story house. i was able to receive connection at a location outside my front of the house for my Ring Doorbell i have previously used a plug in wifi extender for before. the netgear genie help does aid in the installation and help view your connectivity conveniently on your phone. devices features the new speedy docsis 3.1 providing reliable and quicker downstream/upstream speeds. the item is costly but you absolutely get what you pay for and in my opinion, it is totally worth it. i would recommend this device to everyone. netgear makes the best routers in my opinion.I would recommend this to a friend

fast , reliable and easy setupPosted .
Pro: 1. Very easy setup, I don't need call Comcast to request attractive my new modem any more. This is safe me a lot of time and I can get my internet right away after few click. 2. Very fast, with new Docsis 3.1 providing reliable and quicker downstream/upstream speeds , I don't feel lag with 2 on-line game + 3 video stream on different rooms. 3. Better receiving, I can remove my wifi extension from one of room after install this unit.I would recommend this to a friend

I love this MODEM and ROUTER COMBOPosted .
Well, I always used a MODEM and ROUTER COMBO in the house. It is about 2400 SQ FT but if you include basement adds to 3400 SQFT. The time of downloading video is now here and I needed to upgrade to reduce the buffering and allow everyone to watch programing on their device. Or if I work from home where I need to use VOIP to communicate with the office. It makes sense to get the latest technology. This ROUTER can be configured to allows my family the 2G BAND to allow up to a certain amount for them and their downloads. And I get to be KING with the 5G BAND which allows faster download speeds for my office actives. You can also, setup Guest on 2G or 5G bands but I do not unless the kids have a party and then I can open it quickly. I did not find any dead spots in the basement or on the second floor as this is located on the first floor. I and very pleased with this device and would recommend it. I use the BEST BUY recycle program to get rid of an older router that was wired so save a few bucks on this wireless baby that can last for many years. When the internet prices are cheaper for GIGGA speed, then you can look to upgrade beyond this device. If your needs are only to download videos and such, then this band width should suffice.I would recommend this to a friend

EX Comcast/Xfinity technician point of view!Posted .Owned for 8 months when reviewed.
This Gateway(modem/router) is a game changer! I use to work at Comcast/Xfinity and their devices are capped out at certain speeds and channels. The company is moving towards a Docsis 3.1 system so this is definitely a step in the right direction for our home. The coverage is also good. 1000 sq ft home. Basement, first floor, and them 2nd floor. My devices are on the 5ghz. Everyone else's are on the 2.4 frequency. I have a 250+ mbps plan. Devices connected via wifi: - 4 cell phones - 3 tablets - N. Switch Devices harded line: - 4k PoE security system 4 cameras. Unit has 33ft Cat8 from Router. - Ps4 connected via 33ft Cat8 ethernet cord - 4k player - Vonage 12+ devices and this unit keeps going. Activation: Call in the router to your cable provider after you have allowed it to sync up to the provider's signal. It can be a couple minutes to over an hour before I recommend you call it in. Router Setup is easy: routerlogin.com in your search bar and this will allow you to access the routers main menu. I can't understand why people have a hard time with this unit. A lot of issues can be resolved on the cable providers end. If the signal coming into the home isn't sufficient or has fluctuations, then you will continue to have issues like your old setup. Issues can include: -head end -the port at the tap(where your drop cable connects to) -the drop itself(cable running to your home) - lines inside your home. Behind your walls or tacked on the wall. If your home is new, this doesn't matter. It's the quality of the cable used and also if they used staples to connect your cable on wooden studs. Any pinch or penetration of the cable line can cause major fluctuations the cable signal effecting both tv and internet signals. -quality of cables and splitters used. I know this seems like alot but i have countless experiences where I had to switch out cables and Best Buy/RCA splitters because of DIYers. As long as your signal is strong and consistent, you should have no issues with this Gateway!

Great future proof modem and ok WIFi routerPosted .
This has a great cable modem that is built in being Docsis3.1. I am unfortunately not really able to utilize the full amount yet as my cable provider is not there yet. This does have a USB 3 so I do use this for a hard drive just to catche on the network. The WiFi proformace has is ok. But the speeds are a little exaggerated since it uses 1024QAM, I am a RF and network engineer, and Getting that high of a modcod you could only use that in the same room otherwise you are going to get lower modcod such as you get further away. Other then that it works well. I do believe it is a little over priced since the WiFi side is mediocre. But it looks cools and has 4 antennas forMIMOI would recommend this to a friend

A Screamin' Eagle; no, make that NighthawkPosted .
This DOCSIS 3.1 modem/router provides 32-down and 8-up channel bonding; latency-free speeds are assured with up to gigabit (1 Gbps) at 2.4 GHz and 2.165 Gbps at 5.0 GHz. Stream multiple HD movies, music videos, and digital music concurrently using one or more devices (computers, notebooks, tablets, smartphones). Setup is a breeze and activation with ISP (Cox, Xfinity) is straightforward--just ensure required information is collected beforehand (model, s/n, MAC address, ISP account number). On that note, three MACs are errantly provided by Netgear (at least on my unit): On the rear label along with the model and s/n; on the sticker atop the unit; and internally when using the Netgear web configuration manager. All three were identical except the last digit; use the MAC address on the rear label. Setup done within a half-hour and network back online soaring high in the digital sky with speeds of a diving screaming eagle--make that a screaming Nighthawk! No problem accessing the network anywhere within this 3200sf house (and the unit is not centrally located).I would recommend this to a friend

Almost.....Posted .Owned for 2 months when reviewed.
My 1st Nighthawk lasted just a little while before the signals just started dropping. Ofcourse Geek Squad replaced ASAP!! THE 2ND one lasted almost 2 years and BOOM!!...THE 5G Signal started dropping constantly!! And unfortunately the antennas are kinda fragile so, try to place it in a permanent spot from the start!!! When this device is fully functioning...LOOKOUT!!! IT CAN BE A POWERHOUSE!!! NO LAGS, BUFFERING WHILE STREAMING ETC.... FAR REACH IN LARGE HOMES AS WELL.

Q: QuestionThis Netgear C7800 looks like the wireless capable modem/router of the Netgear cm1000. I have seen that the CM1000 is compatible with Spectrum but I have not seen anything about the C7800. Is this modem/router compatible with Spectrum? Thanks.
Asked by GusDiaz.
- A:Answer Let me answer my own question. Yes, this works with Spectrum, just got it connected with the 400 MB download plan and is doing 422. Waiting for the upgrade to 1 Gig to be processed in order to get more speed.

Q: QuestionI bought this modem/router combo 2 days ago and setup was pretty simple, however i wouldnt get gigabit speeds max speed recorded was 100 mb and sometimes 2 mb, Anyone know how to troubleshoot it? Altready called ISP..on their end its showing them 1.06 Gb.
Asked by Paul.
- A:Answer Hope you've managed to solve your slow speed issue. Writing the following in the hope that my experience may benefit someone else. All your testing should be done wired, with a capable computer (including reliable 1GHz network adapater). Do NOT test via wireless! That won't tell you the full story. I suggest you first verify that you are consistently getting close to the 'promised' speeds with a rental modem from your cable provider. If not, the problem might be the capabilities of your computer, or it might be the test center location you're using for measuring your speeds. On Win 10, you'll get much better, and more consistent tests if you download Ookla's app from speedtest.net. It does a decent job of auto-selecting test centers, based on ping speed, but you should probably play around with various test centers to make sure you've got a reliable measurement source. Speaking from personal experience, there can be MANY problems between 'the box outside' your residence, to where the signal ultimately reaches your computer. In my case, I was experiencing wildly inconsistent speeds. Managed to get my provider to replace ALL the cabling between the box in the basement of the apartment building, where I live, all the way to my computer (and DVR, etc.) Best to limit the number of splitters used, since each one loses signal. After all that, speeds were still wildly inconsistent. Installed a new copy of Win 10 (since I'd mucked up the regular OS by hastily trying suggestions I found online for increasing internet speed. Bad idea, but I was frustrated. Even with new OS, still had unreliable speeds. Finally found a sympathetic supervisor in the loyalty department. He talked to his boss. His boss recommended a colleague in a department I wouldn't have been able to reach. When they checked the line, they found the signal to the outside box was too strong. A line tech fixed that without my involvement. Since that adjustment, my speeds are consistent, and coming in pretty close to the maximum. If you take all the above into consideration, and get your ISP to go 'above and beyond' to deliver the speed you're paying for (consistently), this modem/router should give you slightly better speeds, without the monthly rental cost. In general, I suspect that newer construction is less likely to have problems like this. In my case, I'm living in a building that's about 112 years old. The cabling in the basement is a bit of a rat's nest, with many splitters and extenders. My last technician was awesome - checking ALL the taps from the feed in the basement, as well as all coax junctions in my apartment. Best of luck to all who are dealing with this issue. The above information was gleaned from about 50 hours of effort, 5 or 6 installer appointments, and far too many hours spent on hold, developing a strong dissatisfaction with call centers in other countries/continents. BTW - Netgear has decent products, but working with their tech support can be EXTREMELY frustrating. Good luck.
