How to Set a WEP/WPA/WPA2 Key

Refer to the instruction manual provided with the access point or contact its manufacturer and check the access point settings. Make sure that the computer and the access point can communicate with each other, then set up the machine to match the settings of the access point.

• 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 access point, the printer, and the computer.

  In order to communicate with an access point that uses automatically generated WEP keys, you must configure the machine to use the key generated by the access point by entering it in hexadecimal format.

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

  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 to enter a WEP key.

  For details, see Changing the WEP Detailed Settings.

• When using WPA or WPA2

  The authentication method, passphrase, and dynamic encryption type must match on the access point, the machine, and the computer.

  Enter the passphrase configured on the access point (a sequence of between 8 and 63 alphanumeric characters, or a 64-character hexadecimal number).

  Select either TKIP (Basic Encryption) or AES (Secure Encryption) for the dynamic encryption method.

  For details, see Changing the WPA or WPA2 Detailed Settings.
