  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 Wireless Routers screen, follow the on-screen instructions and set the key length, the key format, the key number, and the authentication to enter a WEP key.
