What is the WLAN card?

Wireless local network (WLAN) is a device that allows the computer to connect to wireless networks. Using computer and businesses to connect multiple devices to the wirelessly broadcast network can also be called wireless card or Wi-Fi card. WLAN differs from Ethernet -based cards, because WLAN hardware allows a computer to connect to a wireless transmission network without the use of connecting cables. Wireless cards may look like a card with connecting pins at the end, but they also come in portable forms that look like PIN units.

Many people and businesses use WLAN card settings daily, often connected to the home or working network. Most wireless networks use technology called multiplexing the frequency division to transfer data. Wireless networks are sometimes called wireless networks of the local area (lawn). Wireless networks often use a modem to provide WLAN access to Internet access.

The

WLAN card can be installed as a piece of permanent hardware inside the computer, or it can be a piece of peripheral hardware connected to an external port on the computer. The plug-in WLAN cards usually connect to the computer using the Universal Serial Bus (USB) ports. New notebook computers usually come up with WLAN installed devices. Some manufacturers refer to a notebook with a built -in WLAN ability as a computer with a WLAN notebook. Examples of common WLAN card manufacturers include D-Link®, Linksys®, HP® and Netgear®.

Some computers are created to make it easier to make the WLAN hardware cards for anyone installed while other computers, especially older computers, have somewhat more complicated installation processes for installation of built -in WLAN cardabout a computer friendly friend. To start the newly installed WLAN card, most computers require the installation of the software driver. The WLAN card driver tells the computer to communicate with the WLAN card. Wireless hardware manufacturers usually include drivers' discs in a package with a new WLAN device or download online.

Local network (LAN) often has faster data transmission than wireless networks, but wires require computer user to remain in the length of the network hardware wire. For a wireless network, users can remain connected from anywhere where they want wireless hardware. WLAN cards sometimes have Ethernet LAN's capabilities as included. Wireless cards without Ethernet plug are often installed next to Ethernet cards that provide computer ability to connect to cable and wireless network connection. When removing problems, it may be useful to connect to cable lanrems with a network connection and can also help with confesGurating computers for network connection for the first time.
