Cannot Communicate with the Machine after Applying MAC/IP Address Filtering or
Entering a WEP/WPA/WPA2 Key to the Access Point
Check 1: Confirm the access point setting.
Refer to the 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 at the access point, confirm
that the MAC addresses 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.
