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.

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:

ISCONNECT

WHEN

ATTEMPTING

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.
