your computer. Sometimes, turning off the power and then turning it back on recovers

from a network communication issue.

Step 3 - Run the Wireless Network Test

For wireless networking issues, run the Wireless Network Test. To print a Wireless

Network Test page, press and hold the

(Resume) button, and then press the

(Wireless) button. If a problem is detected, the printed test report includes

recommendations that might help solve the problem.

TIP: If the Wireless Network Test indicates the signal is weak, try moving the

printer closer to the wireless router.

Advanced wireless troubleshooting

If you have tried the suggestions provided in Basic wireless troubleshooting and are

still unable to connect to your printer to the wireless network, try the following

suggestions in the order presented:

•

Step 1: Make sure your computer is connected to your network

•

Step 2: Make sure that the printer is connected to your network

•

Step 3: Check to see if the firewall software is blocking communication

•

Step 4: Make sure the printer is online and ready

•

Step 5: Make sure the wireless version of the printer is set as the default printer

driver (Windows only)

•

Step 6: Make sure your computer is not connected to your network over a Virtual

Private Network (VPN)

Step 1: Make sure your computer is connected to your network

Make sure your computer is connected to your network—either your wired (Ethernet)

network or your wireless network. If the computer is not connected to the network, you

cannot use the printer over the network.

To check a wired (Ethernet) connection

▲ Many computers have indicator lights beside the port where the Ethernet cable

from the router connects to your computer. Usually there are two indicator lights,

one that is on and another that blinks. If your computer has indicator lights, check

to see if the indicator lights are on. If the lights are not on, try reconnecting the

Ethernet cable to the computer and the router. If you still do not see lights, there

might be a problem with the router, the Ethernet cable, or your computer.

NOTE: Macintosh computers do not have indicator lights. To check the

Ethernet connection on a Macintosh computer, click System Preferences in

the Dock, and then click Network. If the Ethernet connection is working

correctly, Built-in Ethernet appears in the list of connections, along with the

IP address and other status information. If Built-in Ethernet does not appear

in the list, there might be a problem with the router, the Ethernet cable, or

your computer. For more information, click the Help button in the window.
