A wireless router is a network device that performs the functions of a router but also includes the functions of a wireless access point. A router ('rautər in the USA 'rutər in the UK and Ireland, or either pronunciation in Australia and Canada is a Computer whose software and hardware are usually In Computer networking, a wireless access point ( WAP or AP) is a device that allows wireless communication devices to connect to a Wireless network It can function in a wired LAN, a wireless only LAN, or a mixed wired/wireless network. Most current wireless routers have the following characteristics:
- LAN ports, which function in the same manner as the ports of a network switch
- A WAN port, to connect to a wider area network. The routing functions are filtered using this port. If it is not used, many functions of the router will be bypassed.
- Wireless antennae. These allow connections from other wireless devices (NICs (network interface cards), wireless repeaters, wireless access points, and wireless bridges, for example).

WAP functions
The wireless functions operate as a separate nested "mini-LAN" within the router. The devices that connect wirelessly use the wireless router as their hub, and the wireless router presents that "mini-LAN" as a single device to the rest of the LAN. This mini-LAN has the same features as discrete WAPs have.
Wireless routers, access points, and bridges are available that utilize each of the commonly used wireless frequencies (used in the Wireless-B, Wireless-A (and -G), and Wireless-N standards). IEEE 80211b-1999 or 80211b, is an amendment to the IEEE 80211 specification that extended throughput to up to 11 Mbit/s using the same 2 IEEE 80211a-1999 or 80211a, is an amendment to the IEEE 80211 specification that added a higher throughput of up to 54 Mbit/s by using the 5 GHz IEEE 80211g-2003 or 80211g, is an amendment to the IEEE 80211 specification that extended throughput to up to 54 Mbit/s using the same 2 IEEE 80211n is a proposed amendment to the IEEE 80211-2007 Wireless networking standard to significantly improve network throughput over previous standards such The frequency bands for these wireless standards can be used license-free in most countries.
Wireless routers can work with devices in a point-to-point mode, but more commonly functions in a point to multipoint mode. Point-to-point telecommunications generally refers to a connection restricted to two endpoints usually host computers For general information for point-to-multipoint communication refer to point-to-multipoint link.
Wireless devices used that communicate with the wireless router must be set to the same service set identifier (SSID) and radio channel. A service set identifier, or SSID, is a name used to identify the particular 802 Radio is the transmission of signals by Modulation of electromagnetic waves with frequencies below those of visible Light.
Netbooting Wirelessly
Unless you have a wireless card with a PXE-ROM chip built into it, it is not easy to directly netboot over a wireless connection. Network booting is the process of Booting a Computer from a network rather than a local drive BIOS-based PXE algorithms usually only search for a wired NIC card to be used in a PXE netboot. In Computing, the BIOS (ˈbaɪoʊs The Preboot eXecution Environment ( PXE, aka Pre-Execution Environment or 'pixie' is an environment to boot Computers using a network interface NetBoot is a technology from Apple that enables New World ROM Macs to boot from a network
Some users have cleverly connected a Wireless Bridge (i. A wireless bridge is a hardware component used to connect two or more Network segments (LANs or parts of a LAN which are physically separated e. a wireless router or wireless access point set to the "bridge" mode) to the wired NIC card in their PC. The PC then netboots through the wired Ethernet NIC as usual, but the data is then transmitted from the NIC to the Wireless AP/Router connected to it and then wirelessly "across the bridge" to the central Wireless Router.
This solution works pretty well, but of course you must have two Wireless Access Points/Routers (one on each side of the "bridge"). Still, this is sometimes easier than running extra Ethernet cables throughout your home.
