How to Fix an HP Printer Lost WiFi Connection

Follow these troubleshooting steps in order.

1. Restart Your Devices

Power cycle:

• HP printer
• Computer
• WiFi router

Wait at least 60 seconds before turning everything back on.

This resolves many temporary network issues.

2. Check the Wireless Signal

Ensure:

• The printer is within range of the router.
• No large walls or metal objects block the signal.
• The wireless indicator light is solid rather than blinking.

If the signal is weak, move the printer closer to the router.

3. Reconnect the Printer to WiFi

Most HP printers include a wireless setup wizard.

Steps:

1. Open the printer’s Settings menu.
2. Select Network.
3. Choose Wireless Setup Wizard.
4. Select your WiFi network.
5. Enter the correct password.
6. Confirm the connection.

Once connected, the wireless light should remain solid.

4. Verify the WiFi Password

Many connection issues occur after changing the router password.

Double-check:

• Uppercase and lowercase letters
• Special characters
• Correct network name (SSID)

If necessary, reconnect the printer using the updated credentials.

5. Remove and Re-add the Printer

On Windows:

1. Open Settings > Bluetooth & Devices > Printers & Scanners.
2. Remove the HP printer.
3. Add it again after reconnecting to WiFi.

On macOS:

1. Open System Settings > Printers & Scanners.
2. Delete the printer.
3. Add it again using the “+” button.

Update HP printer drivers.

Outdated drivers can interrupt wireless communication.

Update:

• Printer driver
• HP Smart software
• Firmware

Installing the latest updates improves compatibility with Windows and macOS.

Check Router Settings

Sometimes the issue isn’t the printer.

Verify your router:

• Broadcasting the correct SSID
• DHCP enabled
• MAC filtering disabled
• WPA2 or WPA3 security enabled
• Stable internet connection

Restarting the router can refresh network assignments.

Fix HP Printer Offline After WiFi Disconnect

If the printer reconnects but still appears offline:

• Clear the print queue.
• Restart the Print Spooler service (Windows).
• Disable “Use Printer Offline”.
• Set the HP printer as the default printer.
• Assign a static IP address if the printer frequently disconnects.

HP Smart App Cannot Find Printer

If HP Smart cannot locate your printer:

• Connect your mobile device to the same WiFi network.
• Enable Bluetooth during setup if required.
• Restart the HP Smart App.
• Refresh the printer list.
• Reinstall the app if necessary.

Reduce future connection problems with these tips:

• Keep printer firmware updated.
• Place the printer close to the router.
• Avoid frequent router resets.
• Use a stable 2.4 GHz network if supported by your printer.
• Assign a reserved IP address in your router settings.
• Restart the printer occasionally.
• Keep network drivers updated on your computer.
