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.

Most Virtual Private Networks (VPNs) allow computers to communicate with only the VPN and no other network at
the same time. Disconnect from the VPN before installing the driver on the computer or before running the wireless
setup on the computer.
To check if the computer is currently connected to a VPN, open your VPN Client software and check your VPN
connections. If you do not have a VPN Client software installed, check the connections manually using the Windows
VPN Client.
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.
