Resolving intermittent wireless communications issues
You may notice that your printer works for a short time and then stops working, although apparently nothing has
changed on your wireless network.
Many different issues can interrupt network communications, and sometimes more than one problem exists at the
same time. Try one or more of the following:
DISCONNECT FROM ALL VPNS WHEN ATTEMPTING TO USE THE WIRELESS NETWORK
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, 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.
TURN OFF THE ACCESS POINT (WIRELESS ROUTER) AND TURN IT BACK ON
Wait one minute for the printer and computer to reestablish the connection. This can sometimes refresh network
connections and resolve connectivity issues.
