HECK YOUR ADVANCED SECURITY SETTINGS
•
If you are using MAC address filtering to limit access to your wireless network, you must add the printer MAC
address to the list of addresses allowed to connect to the wireless access point.
•
If you set the wireless access point to issue a limited number of IP addresses, you must change this so that the
printer can be added.
Note: If you do not know how to make these changes, see the documentation that came with the wireless network,
or contact the person who set up your wireless network.
Communication with printer lost when connected to
Virtual Private Network (VPN)
You will lose your connection to a wireless printer on your local network when connected to most Virtual Private
Networks (VPNs). Most VPNs allow users to communicate with only the VPN and no other network at the same time.
If you would like to have the ability to connect to your local network and to a VPN at the same time, the system
support person for the VPN must enable split tunneling. Be aware that some organizations will not allow split
tunneling due to security or technical concerns.
Wireless configuration does not continue after the
USB cable is attached
Check the USB cable
If the configuration software does not allow you to continue configuring your printer wirelessly after you attach the
USB cable, there may be a problem with the cable. Try one or more of the following:
•
Make sure that the USB cable is not damaged. If there is any visible damage to the USB cable, try using a new one.
•
Attach the cable directly to the computer and the printer. Hubs, switch boxes, and docking stations can sometimes
interfere with the USB connection.
•
Make sure the USB cable is correctly attached.
1 Attach the large, rectangular connector to any USB
port on your computer. USB ports may be on the
front or the back of the computer, and may be
horizontal or vertical.
