• Check 1: Confirm the access point setting.
Refer to the instruction manual provided with the access point or contact its manufacturer to confirm
the access point setting. Make sure that the computer and the access point can communicate with
each other under this setting.
• Check 2: If you are performing MAC address filtering or IP address filtering at the
access point, confirm that the MAC address or IP address for both the computer or
the network device and the printer are registered.
• Check 3: If you are using a WEP/WPA/WPA2 key, make sure that the key for the
computer or the network device and the printer matches that set to the access point.
Besides the WEP key itself, the key length, key format, the key ID to use, and the authentication
method must match among the machine, the access point, and the computer.
Normally, select Auto for the authentication method. If you want to specify the method manually,
select Open System or Shared Key according to the setting of the access point.
