What is the WLAN router?

The router is a device that moves data packets between computer networks. The router usually connects the network of the local area (LAN), for example in the home or office, with a wide network (WAN), which can be the modems of the cable modem or digital service (DSL). In the simplest point of view, the router for the most common use is a traffic cop between a computer or network and the Internet. The wireless LAN (WLAN) adds additional functionality to the router, allowing wireless access to it from a device equipped with wireless network or WLAN cards. WLAN router will have the same function, but also contains a wireless access point 802.11. This means that the number of devices that can be wirelessly connected to the WLAN router is limited only by the WAN width to which it is connected.

in a home environment where the user connects to a cable modem or DSL modem, many of which have only one open port, the WLAN router can be the best option. However, many cable and telephone companies offer withoutwire skills built into their modem. This eliminates the need for a separate WLAN router.

In the office network environment, it is usually in place a network router, so adding a WLAN router creates problems. In this case, there would be two devices that would try to do the same job. For these types of networks what the user wants, the router is not WLAN, but the WLAN access point. WLAN router is actually a normal router with WLAN access point into it. The WLAN access point only separates these two functions.

For computers that do not have built -in WLAN cards, there are other options. You can buy disgust WLAN, which connects to the ports of Universal Serial Bus (USB), which will make the computer wireless. For old laptops, there are WLAN cards that connect to card slots. For desktop computers you can install the USB WLAN or WLAN card.

whether it is usedThe WLAN router or WLAN access point is a problem. These devices uncontrolled, can keep networks vulnerable to nearby hackers. For this reason, a safety device known as a cable equivalent to privacy (WEP) has been developed. These are a number of random letters and numbers that the device must enter to access WLAN or WLAN access point.
