Wireless broadband boxes in Europe, the Middle East, and Africa such as LiveBox, AliceBox, N9UF Box,
FreeBox, or Club Internet may require you to press an association/registration button when adding the
printer to your wireless network.
If you are using one of these boxes and need more information, then see the documentation that came
with your box, or contact your Internet Service Provider (ISP).

OVE YOUR ACCESS POINT AWAY FROM OTHER ELECTRONIC DEVICES
There may be temporary interference from electronic devices such as microwave ovens or other
appliances, cordless phones, baby monitors, and security system cameras. Make sure your access point
is not positioned too closely to these devices.

OVE THE COMPUTER AND OR PRINTER CLOSER TO THE ACCESS POINT
The range of your wireless network depends on many factors, including the abilities of your access
point and network adapters. If you are having trouble printing, then try placing the computer and
printer no more than 100 feet apart.

HECK THE WIRELESS SIGNAL QUALITY
Print a network setup page and check the signal quality. If the signal quality is listed as good or excellent,
then another factor is causing the problem.

HECK YOUR ADVANCED SECURITY SETTINGS
• If you are using MAC (Media Access Control) address filtering to limit access to your wireless
network, then you must add the printer MAC address to the list of addresses allowed to connect
to the access point.
•
If you set the access point to issue a limited number of IP addresses, then you must change this so
that the printer can be added.
Note: If you do not know how to make these changes, then see the documentation that came with
the access point, or contact the person who set up your wireless network.
M
AKE SURE YOUR COMPUTER IS CONNECTED TO YOUR ACCESS POINT
•
See if you have access to the Internet by opening your Web browser and accessing any site.

If there are other computers or resources on your wireless network, then check to see if you can
access them from your computer.
