A security key is like a password. All devices on the same network will share the same security key.
• If you are using the WPA type of security, make sure you entered the correct key. Security keys are case
sensitive.
• If you are using the WEP type of security, you should enter the key as a series of digits (0–9) and letters (A–F).
Note: If you do not know this information, see the documentation that came with the wireless network, or contact
the person who set up your wireless network.
Check your advanced security settings
• If you are using MAC address filtering to limit access to your wireless network, you must add the printer's MAC
address to the list of addresses allowed to connect to your wireless access point (wireless router).
• If you set your wireless access point (wireless router) to issue a limited number of IP addresses, you must change
this so that the printer can be added.
Note: If you do not know how to make these changes, see the documentation that came with the wireless network,
or contact the person who set up your wireless network.
