Like a wired router, a wireless router is a device that is used to provide access to the Internet or a private network. The only difference between a wired and wireless router is that computers on a wireless router network connect without the use of an ethernet cable.

A wireless router works by connecting to your phone line, which has broadband data sent through it. From there, the router sends out radio signals that can be synchronized with various devices, including but not limited to personal computers, laptops, tablets, wireless speakers, and cell phones.

This means that instead of having to connect a physical Ethernet cable from your laptop or computer to the router, you can connect over the air using the 802.11 wireless standard. The standard gets its name from the frequency of the radio waves used to transmit data to and from the device, allowing it to do everything from browsing the web, watching YouTube, or downloading files entirely over the air.

Wireless routers are essential in homes where multiple people want to connect to the Internet from more than a single base station, especially if you have a smartphone, tablet, or laptop that does not come with its own ethernet port.

The difference between a wireless router and an Internet modem is as follows: A modem takes the signal from your ISP (Internet Service Provider) and converts it into data that can be downloaded or uploaded from computers in your home. It does this by transforming the signal that travels over your cable line, telephone line (DSL), or fiber optic line, and then pushes that information into the router.

Your router is responsible for dividing that signal into more than one channel, so that more than one device can share a single IP address. Your home receives an address sent by the ISP, and a router splits it into any number of individual transmissions that go to all of your favorite devices.

The reason this is confusing to many consumers is because lately, it has become the new trend for ISPs to bundle their wireless modems and routers into one unit, despite the fact that the two devices perform very different independent functions. Bottom line: The modem converts your ISP's raw data into an Internet signal, and your wireless router splits it so that more than one person can use it at once.
