I've set up the password security for my Dynalink wireless router but now i cant even use the wireless internet pls help

Theencryption key secures your data from unauthorized access. The router's password is a Passphrase or the WEP or WPA orWPA2 encryption key. The Passphrase generates the WEP or WPA or WPA2 encryptionkey and this is in the router's wireless settings. To connect to your wireless router, configure the router'swireless settings ie SSID, plus the WPAor WPA2 encryption key and then configure wireless cards in the laptops and orcomputers with these router's wireless settings. Then the laptops and desktopcomputers can communicate with your wireless router.
