[Hardware]Connect the PC to wireless internet (Wi-FI)




Here is a trick designed to help people who want Internet without making use of any cable:
We will consider a wi-fi based solution, the easiest and most popular.

The Wi-Fi


The easiest solution for connecting the PC to wireless Internet is the wireless solution.
To use the wi-fi, you must already have an internet router/modem (allowing transmission of information) these boxes play the role of the"sender".
This type of equipment usually offer a throughput of 54 Mbps (802.11g), with a range of about 100 meters, but there are other standards. Adequate for surfing and chatting, but a bit limited for download. It is possible to connect multiple PCs to a router, but with a necessarily limited flow with multiple users.

Equipment needed


NIC: Network Interface Card

To receive the signal from the box, it is necessary that the PC has a network card (normally most PCs have, even being old enough).
You can still check:

Windows:
  • Click on "Start"
  • Right click My Computer (or Computer in Vista) and click on "properties"
  • Click on the tab "hardware"
  • Click on "Device Manager"
  • Click on the + sign in front of NIC
  • The name and brand of the card appear if the pc has a network card.


After verifying that your pc does have a network card, you need a "receiver" connected to the PC to receive information from the router/modem.
Note: The notebooks are usually already equipped with a wifi receiver.

The USB WI-FI Key


This is the simplest solution, and very inexpensive, you can buy them in supermarkets and on the Internet.
Latest keys can provide a throughput of 300 Mbps maximum (802.11n).
Must purchase a key corresponding to the standard of your router (802.11g is the current standard and most common).

The Wi-Fi card


The wi-fi card is another solution, it is more difficult to install because it generally fits into a port on the motherboard (typically PCI). To get there, we must open the computer case and recognize the corresponding port on the motherboard of the computer.
The card may offer a maximum throughput of 300Mbps (802.11n) with a longer range than the USB key, so it's more comfortable. But this is only useful if your box has 802.11n (300 Mbps).

Setting the network


Once your purchase made, it must set the wireless network.
To prepare all this, you will need:
  • The NIC
  • The installation cd of the Wi-Fi Card/USB Key
  • The security key (WEP or WPA) on your Internet box, usually located on your box to the back or bottom, in the manual box, or you can find the code in the settings box Internet via Internet.
  • The SSID (network name of your box) available on the manual or via the internet within the parameters of the internet box.
