Wireless Router !!

April 5, 2012

wireless router is a device that performs the functions of a router but also includes the functions of a wireless access point and a network switch. It is commonly used to provide access to the Internet or to some other Computer Network . It does not need a cabled connection. It can function in a wired LAN (local area network), in a wireless-only LAN (WLAN), or in 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 which connects to a Wide Area Network , typically one with Internet access. External destinations are accessed using this port.
  • A wireless antenna that allows connections to other wireless devices, such as NiCS, wireless repeaters, wireless access points, and wireless bridges.This antenna typically uses the Wi-Fi standard.

Some wireless routers also include a DSL or cable modem in addition to the other components.

The wireless router can be thought of as the very heart of the wireless network, and it functions in the same manner as a cordless phone base station. What most people refer to as being a wireless router is actually a device that has dual functions, which includes the access point, and the router itself.

The access point will be responsible for connecting the computers in the facility to one another, and it will then connect all of these to the Internet. An office which is substantially large in size may have access points or routers which are stored in distinct boxes to obtain a larger range via the network. However, these are more expensive than the typical wireless router, because they have a much larger range.

Wireless Router Features :

Every computer that exists within the wireless network will need to have a receiver which works with the wireless router. These are referred to as being network adapters, and they will typically have either a USB device or a network card. For most laptops, a network card adapter can be used, but most contemporary laptops today have such devices built in.

Older laptop models will typically need to use external devices to connect to the network. My best advice to those that wish to buy wireless routers is to make sure they purchase both the router and adapter from the identical company, as this reduces the likelihood of compatibility issues occurring. Additionally, when you purchase both from the same company, you can be assured of receiving good technical support.

Wireless Router Advantages :

There are many advantages to using a wireless router over a traditional wired router. First, there is no large group of wires that can become tangled up together. This means that once you’ve set up your wireless router, the days of tripping over wires, or accidentally pulling them out of their sockets, are over.

Additionally, with a wireless router, you literally have the freedom to carry your laptop anywhere in your home and office, and still have access. As long as you stay within the range, you should be fully connected. The mobility that comes with a wireless network can greatly increase efficiency and freedom, since you are not tied down to one location, and can move about as you please. This is the greatest advantage of using wireless routers.

Wireless Router Issues :

However, wireless routers are far from perfect. The biggest issue that they face is security. While advances have been made in recent years on wireless network security, the truth of the matter is that homes or offices that wish to have the most secure connection must use wired networks.

Additionally, because wireless routers are a newer technology, as expected, they are more expensive than their traditional wired router counterparts. Another issue that many people have noticed with wireless routers is a decrease in speed.

The farther you move away from the router, the weaker your connection will become. While improvements continue to be made, these are the key issues that one should consider when purchasing one.
