Q: I 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?

A: 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: Which router works the best with this modem?

A: Any of the Nighthawk Routers would be a good match. The choice of which one depends on your usage priorities.

Q: If height is an issue , can this device be laid on its side?

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

A: 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: Can 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?

A: 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: Why am I not getting internet when I connect my laptop up to one of the LAN ports?

A: 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: Does this Modem support Comcast Xfinity Voice?

A: No. Look at the Netgear model CM1150V-100NAS which has voice too.

Q: Is this model compatible with spectrum cable service provider?

A: Yes. 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! LOL!
