When using WEP

The key length, key format, the key to use (one of 1 to 4), and the authentication method must match among the wireless router, the machine, and the computer.

Normally, select Auto for the authentication method. Otherwise, select Open System or Shared Key according to the setting of the wireless router.

When the WEP Details screen appears after clicking Set on the Search screen, follow the on-screen instructions and set the key length, the key format, the key number, and the authentication method to enter a WEP key.

Either TKIP (basic encryption) or AES (secure encryption) is selected automatically for the dynamic encryption method.
