Yes, this is only a router. The order is: I.S.P. hookup to modem to router to devices.

Yes. This router allows you to create a network of computers and share your existing iternet connection. However, it is not a substitute for your DSL or cable modem. It does work with it.

This just emits a wireless signal. The modem is normally what you need to worry about being compatible. Based off that fact, yes it is.

This is not a modem, this is a router. You should get the difference clear and make sure you know what you need before you lay down any money.

You don't need this modem then. You need a wireless router or a wired router, whichever you prefer.

Not so sure. You should ask the seller. I bought one and it's working great with my modem.

May have to Google that. I have a security system that it works through so they will need some sort of a modem or something. Sorry I can't be of more help.

All the other answers are correct, but what many people may not realize is many "modems" are configured as routers too. You need to determine that first.

The modem has one, almost all of the modems have (1) Ethernet port. You need to connect a router to add additional Ethernet ports in order to share the connection (or have WiFi).

Yes, Router will be needed to connect wireless devices.Modem is a short of access point to access intrrnet from your service provider but using ethernet cable. You can buy separate router and create your own wireless network.

you need 2, it comes just like it is shown. I was using it to extend so if not plugged into the router or modem, you also need an ethernet coupler, similar to what you use to connect to phone lines to make them longer, but for ethernet cords.

This device is only a wireless router. You need a modem and or modem/router combo. This product is not what you need.

Like others have mentioned, there are two devices in the pack. But one is to be connected to the source (like say modem) and another to the laptop/desktop which will communicate through modem to the internet. So if you want to connect more than one laptop/desktop then you can order single additional units or order another pack. You only need one for the modem, additional units just communicate with the same which connects to the modem. In fact I have different model numbers and they still work together.

This is not a cable modem, so it requires an ethernet cable as an input. So it can be a replacement if it you currently have an ethernet cable into your house.

Yes it is, no need for both modem and router. A free outlet and more space on top your your desk!

I did not have to buy any cords. All of the cords were included. Make sure before you buy that all cords are included with the modem.

No you need the modem that Comcast provides, it's a lot bigger with a different config. This one quit after a couple of months use and they would not refund my money just offered another junk one like it.
