CHECK YOUR WEP KEY OR WPA PASSPHRASE
A WEP key or WPA passphrase is like a password. All devices on a WEP-secured wireless network must share the
same WEP key, and all devices on a WPA-secured wireless network must share the same WPA passphrase.
Note: Make sure you copy it exactly, including any capital letters, and store it in a safe place for future reference.
If you are using WEP security
A valid WEP key is:
• Exactly 10 or 26 hexadecimal characters. Hexadecimal characters are A–F, a–f, and 0–9.
or
• Exactly 5 or 13 ASCII characters. ASCII characters are letters, numbers, and symbols found on a keyboard.
If you are using WPA security
A valid WPA passphrase is:
• From 8 to 63 ASCII characters. ASCII characters in a WPA passphrase are case-sensitive.
or
• Exactly 64 hexadecimal characters. Hexadecimal characters are A–F, a–f, and 0–9.
If your wireless network is not using security, then you will not have a security key. Using a wireless network with
no security is not recommended because it can allow intruders to use your network resources without your consent.
CHECK MAC ADDRESS
If your network uses MAC address filtering, make sure that you include the MAC address of the printer in the MAC
address filter list. This will allow the printer to operate on the network. For more information, see “How do I find
the MAC address?” on page 100.
