A wireless router is essentially a router in which doesn’t require physical connections (that is, cables). A router is hardware that links computer networks. It is a networking device which functions as a traffic cop and a mailman put together, deciding where information should go and the manner of its travel. Certainly the most common application for a wireless router nowadays is to offer internet access for multiple PCs.

Contrary to traditional routers, a wireless router will in addition include the capabilities of a wireless access point. It’s usually used to offer internet access along with access to a computer network, all without the need for wires or cables.

Numerous wireless routers in the market these days offer multiple capabilities for instance LAN ports that allow the device to function as a network switch. Wireless routers have come a long way in a fairly short time.

However, they all still have limits on the real speed provided as a result of interference, with things like distance and types of obstacles over that distance playing major roles. Security also is still a prime concern, as well as the rapid deployment of high speed internet all over the country only raises the urgency.

In fact, the industry’s first signal encryption scheme, Wired Equivalent Privacy (WEP), was very publicly cracked. A far more robust algorithm known as Wi-Fi Protected Access (WPA) was quickly announced as a replacement, followed by WPA2 the very next year.

Indeed, security is an important reason why a router is deemed a necessity to many, even if there are no networking requirements involved. A router in this situation serves essentially as a sort of gatekeeper. In addition to software firewalls and so on, having a physical device interceding in between the computer and the internet will mean that an extra layer of insulation or protection, so to speak, is involved. Think of it as wearing a jacket on a wintry day even though you may already have a sweater on!
