Introduction to Wireless Router

Wireless Router is a network communication device that is used to route the traffic based on the IP addresses.  Wireless router provides the internet connection sharing, networking and the firewall features.  It can also provide the NAT (Network Address Translation) features.  It provides the great mobility for the notebook and portable computes. There are many specifications like 802.11a, 802.11b and 802.11g.  802.11g is the best choice as it provides the better speed, security, compatibility, firewall and other features. 

There are many manufacturers of the router and the most common are Cisco, Juniper, D-Link, LinkSys, Belkin and Netgear.   Some routers come with the built-in DSL or cable modem capabilities.  While purchasing the router for your wireless network makes sure that your router is compatible with all the other devices in your network.  You also need to check that it has the firewall, NAT, VPN, Ethernet compatibility and security features. 

To increase the range of your router you can replace the antenna with a better one.  The computers on the network are equipped with the wireless transceivers that are either placed with the PC card slot or plugged into the PC card slot.
A wireless router can also act as a hardware firewall to provide the advanced security features.  Once configured properly, your network can be safeguarded from the internal and external threats.
