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:
D VPN
ISCONNECT FROM ALL
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.
