T
RY ADJUSTING EXTERNAL ANTENNAS
Antennas usually work best if they are pointing straight up. You may find that reception improves if you experiment
with different angles for the printer and/or wireless access point antennas.
M
OVE YOUR PRINTER
Move the printer closer to the access point. Although the possible distance between devices in 802.11b or 802.11g
networks is 300 feet, the maximum range for optimal performance is generally 100–150 feet.
You can find the signal strength of the network on the network setup page.

HECK SECURITY KEYS
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.
C MAC
HECK 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 52.
