In a browser address bar type the admin. address (198.162.x.x):



Router settings:

Use WEP only as a last resort: it's child's play to crack.

Set for WPA or WPA2 if your computers support this level.

And;

Disable: UPnP %26amp; QoS (unless using VoIP),

Enable: Router management username %26amp; bulletproof passphrase,

%26amp; AES



Note: Mac address filtering will prevent accidental %26amp; casual freeloaders, but will not deter committed hackers. Mac addresses are on the front end of packets, therefore un-encrypted and as such, easily copied and used to 'spoof' packets; enabling a 'man in the middle' attacks.



Computer settings

If you're using Windows to configure your Wifi, go to Control Panel%26gt; Wireless Network Connections%26gt; Wireless Networks tab; here you'll need to identify all wifi networks your system 'sees', then for your own (or preferred) network, highlight it, then 'move up' to the top of the list: then, go to 'Advanced' button, tick 'access points only' and uncheck 'Automatically connect to non-preferred networks'%26gt;close%26gt; OKWifi how to change network key from wep to wpa please help thx?
You have to log into your wireless router and change the security settings. The address is different for each make of router, Linksys for example uses 192.168.1.1. The password is also different but usually has admin as the username, password or both. I would search the net for this information, it should also be in the instruction manual that came with your router, or call the vendor.
-WPA will not work on some ethernet (LAN) cards, if I were you I will retain WEP (If you are using WINxp and Vista OS)
