Thanks to a device such as a wireless router you can create an Internet or computer network without any form of cabling. Most routers in the wireless category have LAN ports and a WAN port for the connection to a wide area network. This port helps the user filter all the routing functions. And since no cables are used for the creation of the network, the router includes wireless antennae for the connection with other wireless equipment. This means that the wireless router depends on radio waves for functioning.

It is a lot more convenient to connect devices without cables, not to mention that wireless technology tends to become cheaper too. The local traffic can be directed on the network using the wireless router alone, but for Internet access, a modem is required as well. The modem is usually pre-configured by the cable or DSL (digital subscriber line) Internet service provider. The wireless router thus connects you to the world wide web.

One other type of Internet connection is possible if the wireless router also incorporates a modem. The connection of the appliances thus gets simpler when there are not so many devices to connect. The built-in modem of the wireless router should support any type of Internet access, DSL or cable. There may be just one type of Internet access available with some devices, consequently, you should check to make sure that there is a clear match.

Every wireless router supports one or more different broadcasting standards, and they are specified according to the Institute of Electrical and Electronics Engineering. You’ll find them expressed as the 802.11 standards. There is always a letter such as b, a, g, n and several others that follows this designation, and this letter stands for the protocol. The protocols differ depending on the signal strength and speed, thus, the quality of the operations in the network oscillates with it. You won’t experience any drops of performance or data errors if you have a quality wireless router; with low quality devices such problems appear whenever the laptop is at a distance from the router.

The highest speed available at the moment in terms of standards is 802.11n, but this is only compatible only with the newest electronic appliances. If there is not a match with the portable Wi-Fi device, the network will not work.
