M
OVE THE COMPUTER AND
/
OR PRINTER CLOSER TO THE ACCESS POINT
The possible distance between devices in 802.11b or 802.11g networks is 300 feet, while the wireless network
range potentially doubles in 802.11n networks. The range of your wireless network depends on many factors,
including the abilities of your access point and wireless network adapters. If you are having trouble printing, then
try placing the computer and printer no more than 100 feet apart.
You can find the signal strength of the network on the network setup page.
C
HECK YOUR
WEP
KEY OR
WPA
PASSPHRASE
If your access point is using WEP security, then the WEP key should be:
•
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 your access point is using WPA or WPA2 security, then the WPA passphrase should be:
•
Exactly 64 hexadecimal characters. Hexadecimal characters are A–F, a–f, and 0–9.
or
•
From 8 to 63 ASCII characters. ASCII characters are letters, numbers, and symbols found on a keyboard. ASCII
characters in a WPA passphrase are case-sensitive.
Note: If you do not know this information, then see the documentation that came with the wireless network, or
contact the person who set up your wireless network.
C
HECK THE
MAC
ADDRESS
If your network uses MAC address filtering, then 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 119.
