HP Color LaserJet Pro - Solve wireless network problems

This document contains information to help resolve wireless connectivity issues with your printer.

The following sections include a checklist to verify that the wireless connection is set up correctly, instructions to perform a wireless diagnostic test, and troubleshooting information for common wireless network issues.

Wireless connectivity checklist

Use this checklist to verify that the wireless connection is set up correctly.

Verify that the network cable is not connected.
Verify that the printer and the wireless router are turned on and have power. Also make sure that the wireless radio in the printer is turned on.
Verify that the service set identifier (SSID) is correct. Print a Configuration Page to determine the SSID. If you are not sure the SSID is correct, run the wireless setup again.
With secured networks, verify that the security information is correct. If the security information is incorrect, run the wireless setup again.
If the wireless network is working correctly, try accessing other computers on the wireless network. If the network has Internet access, try connecting to the Internet over a wireless connection.
Verify that the encryption method (AES or TKIP) is the same for the printer as it is for the wireless access point (on networks using WPA security).
Verify that the printer is within the range of the wireless network. For most networks, the printer must be within 30 m100 ft of the wireless access point (wireless router).
Verify that obstacles do not block the wireless signal. Remove any large metal objects between the access point and the printer. Make sure poles, walls, or support columns containing metal or concrete do not separate the printer and wireless access point.
Verify that the printer is located away from electronic devices that might interfere with the wireless signal. Many devices can interfere with the wireless signal including motors, cordless phones, security system cameras, other wireless networks, and some Bluetooth devices.
Verify that the print driver is installed on the computer.
Verify that you have selected the correct printer port.
Verify that the computer and printer connect to the same wireless network.
For macOS, verify that the wireless router supports Bonjour.

Perform a wireless network diagnostic test

From the printer control panel, you can run a diagnostic test that provides information about the wireless network settings.

From the Home screen on the printer control panel, touch the Menu icon, and then touch Settings.
Scroll to and touch Network Reports.
Scroll to and touch Print Wi-Fi Test Report.

The printer prints a test page that shows test results.

Troubleshoot wireless network issues

The following sections reference common wireless network issues. For troubleshooting information, click the section heading to expand it, and then follow the steps provided.

The printer does not print after the wireless configuration completes

If the printer does not print after the wireless configuration completes, try these solutions.

Make sure that the printer is turned on and in the ready state.
Turn off any third-party firewalls on your computer.
Make sure that the wireless network is working correctly.
Make sure that your computer is working correctly. If necessary, restart the computer.
Verify that you can open the printer HP Embedded Web Server from a computer on the network.

The printer does not print, and the computer has a third-party firewall installed

If the printer does not print, and the computer has a third-party firewall installed, try these solutions.

Update the firewall with the most recent update available from the manufacturer.
If programs request firewall access when you install the printer or try to print, make sure you allow the programs to run.
Temporarily turn off the firewall, and then install the wireless printer on the computer. Enable the firewall when you have completed the wireless installation.

The wireless connection does not work after moving the wireless router or printer

If the wireless connection does not work after moving the wireless router or printer, try these solutions.

Make sure that the router or printer connects to the same network that your computer connects to.
Print a configuration page.
Compare the service set identifier (SSID) on the configuration page to the SSID in the printer configuration for the computer.
If the numbers are not the same, the devices are not connecting to the same network. Reconfigure the wireless setup for the printer.

Cannot connect more computers to the wireless printer

If additional computers cannot connect to the wireless printer, try these solutions.

Make sure that the other computers are within the wireless range and that no obstacles block the signal. For most networks, the wireless range is within 30 m100 ft of the wireless access point.
Make sure that the printer is turned on and in the ready state.
Make sure there are not more than 5 concurrent Wi-Fi Direct users.
Turn off any third-party firewalls on your computer.
Make sure that the wireless network is working correctly.
Make sure that your computer is working correctly. If necessary, restart the computer.

The wireless printer loses communication when connected to a VPN

Typically, you cannot connect to a VPN and other networks at the same time.

The network does not appear in the wireless networks list

If the network does not appear in the wireless networks list, try these solutions.

Make sure the wireless router is turned on and has power.
The network might be hidden. However, you can still connect to a hidden network.

The wireless network is not functioning

If the wireless network is not functioning, try these solutions.

Make sure that the network cable is not connected.
To verify if the network has lost communication, try connecting other devices to the network.
Test network communication by pinging the network.
1. Open a command-line prompt on your computer.
  - For Windows, click Start, click Run, type cmd, and then press Enter.
  - For macOS, go to Applications, then Utilities, and open Terminal.
2. Type ping followed by the router IP address.
3. If the window displays round-trip times, the network is working.
Make sure that the router or printer connects to the same network that the computer connects to.
1. Print a configuration page.
2. Compare the service set identifier (SSID) on the configuration report to the SSID in the printer configuration for the computer.
3. If the numbers are not the same, the devices are not connecting to the same network. Reconfigure the wireless setup for the printer.

Reduce interference on a wireless network

The following tips can reduce interference in a wireless network:

Keep the wireless devices away from large metal objects, such as filing cabinets, and other electromagnetic devices, such as microwaves and cordless telephones. These objects can disrupt radio signals.
Keep the wireless devices away from large masonry structures and other building structures. These objects can absorb radio waves and lower signal strength.
Position the wireless router in a central location in line of sight with the wireless printers on the network.
