Q: QuestionI am seeing conflicting answers on the usage of 4 LAN ports in this modem. Can all the 4 LAN ports be simultaneously used with single comcast connection? For example, can 1 port be used by wifi router while other port used for connecting to Roku?

Asked 5 years ago by akty123.

• A:Answer This 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: QuestionIf height is an issue , can this device be laid on its side?

Asked 5 years ago by placement.

• A:Answer I 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.

Q: QuestionI can't afford cable service. Can I buy products that will give me WiFi/internet in my apartment for all my devices and Netflix?

Asked 6 years ago by Joann.

• A:Answer You’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.

Q: QuestionCan you connect to WiFi devices with this Modem or do I need a Router before purchase? If so, what alternative comparable modem/routers with WiFi would you suggest?

Asked 6 years ago by Jay.

• A:Answer This 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?

Asked 5 years ago by Mark.

• A:Answer found 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.

Q: QuestionSince this model offer link aggregation, do I need a router that has the same feature built in? Thanks!

Asked 2 years ago by BigD.

• A:Answer YES: With this modem, you would need a router for any level of wifi service. For Link Aggregation to work, you need a supported router (or switch) and supported device -- most NAS servers have it. In other words, you need support on both ends of the bonded connection. i connect to a NETGEAR Nighthawk® AXE11000 Tri-Band WiFi 6E Router (up to 10.8Gbps) with new 6GHz band. it also provides for Multi-gig for wired needs.

Q: QuestionIs this compatible with Xfinity/Comcast

Asked 5 years ago by BestBuyAndre.

• A:Answer Yes and no. Yes you can use it with Comcast and connect a single wifi switch / router and it will work just fine. No, you cant use the modem's built in switch to create a separate subnet for secondary routers as Comcast only willing to provide a single IP for you to use.

Q: QuestionThis modem has no ONT port. How do I connect it with the internet provider's fiber optic?

Asked 5 years ago by Greg.

• A:Answer Your provider should be providing their own Optical Network Terminal (ONT) to mate to their network specific Optical Line Terminal (OLT). Verizon FiOS and and previous Verizon areas purchased by Frontier will provide an ONT. Google Fiber calls its ONT a Jack. (Model GFLT100, GFLT110, GFLT300). ATT Fiber will also provide its own ONT. That is their demarcation point and everything after it is your equipment (Ethernet Cables / Firewall / Router / etc). The Netgear CM1200 is a DOCIS 3.1 Cable Modem but designed for an entirely different type of network. Like the ONT is "customer side" transceiver of a passive fiber network (BPON / GPON / EPON / NGPON2) and the OLT is the "provider side" equipment. A cable modem is the transceiver on the "customer side" of a coaxial network segment and RF element at the node is the "provider side" of the network. (Most of the time it is fiber after the RF connection between the node and provider's internal network) You should have a piece of equipment at your location to convert fiber to Ethernet. If not, contact the provider and have them install it. If you have it at your location, it should have an Ethernet port on it that you connect your equipment to. If not, contact your provider. They should have people to help you do a self install or send someone to do it for you.

Q: QuestionIs this device compatible with Comcast voice phone calling?

Asked 6 years ago by Henry.

• A:Answer This nighthawk modem doesn't have a phone jack. We have Cox digital phone service and we had to keep the older modem connected to keep using the phone service. The two are connected without any network issues. We use a splitter to connect the two modems.
