A wireless router is a device that performs the functions of a router but also includes the functions of a wireless access point. It is commonly used to provide access to the Internet[note 1] or a computer network. It does not require a wired link, as the connection is made wirelessly, via radio waves. It can function in a wired LAN (local area network), in a wireless-only LAN (WLAN), or in a mixed wired/wireless network, depending on the manufacturer and model.


Most current wireless routers have the following characteristics:

Operating System[edit]

The most common operating system on such embedded devices is Linux. More seldom VxWorks is being used. The devices are configured over a web user interface served by a light web server software running on the device.

It is possible for a computer running a desktop operating system such as Windows to, with appropriate software, act as a wireless router. This is commonly referred to as a SoftAP, or "Software Access Point".

Aside from the OEM firmware, for a couple of wireless routers a third party firmware called OpenWrt is available. It is an open source project with the ambition to mainline support for components found in embedded devices into the Linux kernel.
