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 81.
