Wireless routers are mostly used to access internet or computer networks without having to use a cable connection. The wireless routers are mostly used by those people who have more than one computer in either their homes or offices.

Children use computers which use wireless routers as educational tools. Adults, on the other hand, need routers to browse the internet and for their office work. One of the main reasons why many people choose to use a wireless router is because it reduces the tangled mess of wires.

Instead of using wires to link the computers to a modem, a wireless router uses impulses. There are two types of wireless routers; the 802.11g router and 802.11b. The 802.11g routers allow a user to connect many computers to a network without sacrificing connection speed.

It also allows for quicker printing and file sharing. This router also supports speeds of up to 125Mbps. It also offers a wide coverage area and cannot be easily obstructed or interfered with.

The second type of router 802.11b has speeds of up to 11Mbps. It is used as a cheaper alternative to the expensive g model. The major disadvantage of using this type of router is that it is a little bit slower and it can only be used by a limited number of users.

Wireless routers can also be used as switches and firewalls and can provide Network Address Translation. Wireless routers can either work in a wireless LAN, a wired LAN (local area network) or a mixed wired and wireless network.

Characteristics of wireless routers
-A wireless antenna to enable connections from other wireless devices like wireless bridges, wireless repeaters, wireless access points and Network Interface Cards.
-A WAN port to help connect to a Wider Area Network. The WAN port filters the routing functions.
-A LAN port which performs the same function as network switch ports.

Make sure you have a password to protect your network. If you don�t do this, people nearby can easily access and use your network to browse the internet. It is also very important to choose the right security protocol like WPA2 which is a secure protocol for your home network. WEP can be easily cracked and it is therefore not a very secure protocol.

What to look for when choosing a wireless router

This shows you how far the signal of the router can reach. Since this measurement is determined in a lab like setting expects a little less range when setting it in your home or office. Most of the good wireless routers have a range of around 150 indoors.

USB functionality
Some of the wireless routers have a USB port to for added functionality. This enables you to easily share files on your network or even connect a printer directly to your router making it possible to access the printer wirelessly from your computer which has been connected to the router.

Wired ports
In order to enable you to physically connect a computer nearby with the router, most wireless routers provide wired ports. Computers connected directly with wires will have increased speed and reliability. Therefore, it may not be a bad idea to choose a router having local network ports.

Antenna design
Try to find out whether the antenna’s design is internal or external. Though an internal antenna design may appeal to your eyes since it has no external antenna sticking out, the external antennas give a better range and better performance.
