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, then request the
system support person for the VPN to allow 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.

connections. If you do not have a VPN Client software installed, then 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, then request
the system support person for the VPN to allow split tunneling. Be aware that some organizations will not allow
split tunneling due to security or technical concerns.
