To secure your wireless network is an essential step to prevent a malicious user to use your wireless network. Here are the steps to follow.
Change the user password of your wireless router :
Access the configuration utility of your router is secured with a username and a password. This page is accessed by typing the IP address of your router in your internet browser (eg 192.168.1.1). The first step in securing your new wireless network is to change the password by going to the option to change it.
Define your network name (SSID) :

Any WiFi network has a name: the SSID (Service Set IDentifier). The second step is to change the name and hide at the sight of malicious users. In the configuration utility of your router, change the default SSID name in avoiding it is too simple.Désactivez then broadcast SSID name of your wireless network by checking the corresponding box, so that n 'not appear in the list of possible connections of your neighbors.
Enable encryption on your network (security key) :

Before using your wireless network, it is useful to encrypt it with a digital key to not allow access only to users with it. Two types of data encryption currently exist: WEP (Wired Equivalent Privacy) and WPA (Wi-Fi Protected Access). If your router and your wireless adapters support it, you should opt for WPA encryption key with "pre-shared". However, if your hardware does not support WPA, then select WEP. The manipulation is simple because the digital encryption is created from a sentence you must enter a minimum 5-letter word or phrase in the text box and the router will generate different codes. Do not forget to note (one is enough) because they will be used to connect each computer on the network.
MAC address filtering :
Devices (PC or PDA) connected to a wireless network have a network card fitted with a specific address: MAC address (regardless of it, a computer is defined by its IP address). In the configuration utility of your router, you must activate the filter option and enter the MAC addresses of each of your devices. Thus, only these devices (known on the network by MAC address) can access the network.
Configure machines WiFi :
For each machine that can connect to the network, you need to specify the information listed above. After researching your wireless network, you must change the SSID to match the one you specified for the router. Then enter the numeric key encryption that was specified in the configuration utility of the router. This done, your device should connect to the router and the Internet.
Enable File Sharing :
To share files between computers and devices connected Wifi, you need to enable file sharing. The process of sharing in Windows XP is simple. Select << Control Panel >>, then << Network Connections >> and then click Create a home network or a corporate network. Then select This computer connects to the Internet through another computer on my home network or through a residential gateway. The connection wizard will detect your Internet connection.
To share a folder in Windows XP, right click on the file in question, and choose <<Sharing and Security>> and select the Share this folder option. To then access all shared folders from any machine on the network, click Start then My Network Places.
The technique is the same to a network printer: On the computer to which the printer is directly connected, go to the Start menu and then click Printers and Faxes, then right-click on the installed printer, and select Share.
