Selecting WPA, WPA2, or WPA/WPA2 is recommended for security reason. If your wireless router is compatible with WPA/WPA2, you can also use WPA2 or WPA.

• Using WPA/WPA2 (Windows)

  The authentication method, passphrase, and dynamic encryption type must be the same for the wireless router, the printer, and your computer.

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

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

  For details, see If WPA/WPA2 Details Screen Appears.

  Note

  • This printer supports WPA/WPA2-PSK (WPA/WPA2-Personal) and WPA2-PSK (WPA2-Personal).

• Using WEP

  The key length, key format, key to use (one of 1 to 4), and authentication method must be the same for the wireless router, the printer, and your computer.

  To communicate with a wireless router that uses automatically generated WEP keys, you must set the printer to use the key generated by the wireless router, entering it in hexadecimal format.

  • For Windows:

    When the WEP Details screen appears after you click Search... on the Network Settings (Wireless LAN) screen in IJ Network Device Setup Utility, follow the on-screen instructions to set the WEP key length, format, and the number.

    For details, see If WEP Details Screen Appears.
