- A: AnswerThis is a modem only. A router needs to be connected to port 1. The other ports can only be used if your ISP allows multiple external IP addresses, which in case, you would need another router connected to port 2 for example, if your ISP allows 2 external IP addresses. Again, this is a modem only and does no DHCP. It must be used with a router connected to port 1. If you connect a wireless router to port 1 on this modem, your devices will connect to that wired or wirelessly.

Q: QuestionWhich router works the best with this modem?(4 answers)
A: AnswerAny of the Nighthawk Routers would be a good match. The choice of which one depends on your usage priorities.Answered by OldSarge
Q: QuestionIf height is an issue , can this device be laid on its side?(2 answers)
A: AnswerI bought this modem and had to lay it on its side because it did not fit on the shelf under my desk. It seems to be working fine with no issues. I do wish that the stand connected to the bottom of the modem was removable so that it would be able to lay down flat.Answered by Tigerfan
- A: AnswerYou’ll need to purchase internet only service as if it was cable service. Then need to purchase an internet cable modem and a wireless router. (2 units). Once internet service is active, call internet service provider and tell them you will use your own modem and router. They will ask you for your MAC address numbers located under the modem. They should walk you through rest of modem set up. You will need a pc or laptop to check if internet is working during modem set up. Once finished with internet provider modem set up, they are done. You will have to follow set up instructions for router by yourself. Get a router that says “up to 1 G” down load speeds. Good luck.

- A: AnswerThis is only a modem, not a wifi router. You will need a separate wifi router of some type to have a wireless connection to other devices. I am very happy with this modem and I purchased an EERO whole home wifi mesh system as my wifi solution. This gives me a strong fast signal in every corner of my house. With a normal wifi router your signal will get weaker the farther away from the router you are.

Q: QuestionWhy am I not getting internet when I connect my laptop up to one of the LAN ports?(2 answers)
A: Answerfound that any new connections made to the modem while on will not work until the modem is restarted. best rule, make connections power off modem, wait a few seconds, power modem back on. do not use the modem until synced with isp. for this modem the tiny world icon with a lighting bolt will blink. see picture, middle icon on package. once the icon stops blinking, stays solid green as in picture. any devices connected to the modem can now access the network. if devices are used before the modem has synced. those devices will not get any connectivity. if so, need to restart the process all over. hope that helps.Answered by RBAmaral
Q: QuestionDoes this Modem support Comcast Xfinity Voice?(2 answers)
A: AnswerNo. Look at the Netgear model CM1150V-100NAS which has voice too.Answered by slingload
Q: QuestionIs this model compatible with spectrum cable service provider?(2 answers)
A: AnswerYes. You can register it on your account online, connect it and off to the races. If you were using their equipment before, make sure to get it back to them and a receipt for return or they will report you to a collection agency and ruin your credit... Ask me how I know this!

Pretty darn good!
So far this is working more reliably than my old Arris SB8200. I was having issues with the Arris modem almost daily. Mainly I think it was some communication issues between my ISP/modem/router/extender. I got fed up and decided to buy this netgear modem. This netgear modem (Nighthawk 32x8 DOCSIS 3.1) has not randomly stopped talking to my router or decide to restart in the middle of daily activities. My Arris would constantly have these issues and more. The Netgear LED’s are no where near as bright as the Arris’s (annoyingly bright blue LED). Which I prefer “blacked out” or low brightness because I don’t necessarily hide my tech. The netgear modem stands tall but is reasonably slim I think. I do like the colors of this modem over others. Green LED lights, black casing with a matte grey brushed looking plate surrounding the lights. My max internet speeds are hitting the router so it’s doing the job right. I haven’t yet gone Gig but I’m a plan below pretty consistently at 450Mbps down and 22Mbps up. You will have to compliment the modem with a good router or mesh system. The reason I say this is because if you have a good modem but terrible routers you’re limiting your WiFi. A good modem with a good WiFi setup will ensure you are getting what you pay for in terms of internet speeds. Overall I would recommend this modem. I will be buying Netgear Modem’s in the future from now on.

Great Modem Upgrade!
I wanted to upgrade my modem so that I could remove the one provided by my Internet service provider and increase my network speeds with my router. This was a great choice and was fairly easy to setup! I haven't had any issues while gaming since the switch.

Perfect match for my router and nat type open.
Works well I had it for about 3 months almost and no issues with gaming I own a Xbox series x and s both which get a nat type open with the router I purchased from bestbuy also (ASUS ROG rapture gt-AX11000) gaming router . I will recommend it to anyone who owns a Xbox and that’s looking for a nat type open for them. Also gaming is smooth. I do a lot research before I buy so I know this was the perfect match for my small apartment.setup was a breeze u can use the app or a computer I prefer computer setup it’s more secure .speeds are more then my 1 gig from my provider.
