How to Fix HP DeskJet 2855e Wi-Fi Connection Troubles

Wi-Fi connectivity issues with your HP DeskJet 2855e can disrupt your printing workflow. This guide provides various troubleshooting steps to quickly resolve common Wi-Fi problems and restore your printer’s connection.

1. Restart Your Printer and Router

A simple restart can often resolve temporary glitches in both your printer and router. This is a common and usually effective first step.

1. Turn off your HP DeskJet 2855e printer.
2. Unplug your Wi-Fi router from the power outlet.
3. Wait for approximately 30 seconds.
4. Plug your router back into the power outlet and wait for it to fully restart.
5. Turn your printer back on.

2. Check the Printer’s Wi-Fi Signal Strength

A weak Wi-Fi signal can lead to intermittent or failed connections. Verifying signal strength can point to placement problems.

1. On the printer’s control panel, navigate to the network settings.
2. Look for the Wi-Fi signal strength indicator.
3. If the signal is weak, move the printer closer to your Wi-Fi router.

3. Verify Wi-Fi Network Credentials

Incorrect Wi-Fi network name (SSID) or password can prevent the printer from connecting. Double-checking credentials can solve connection issues.

1. On your computer or mobile device, verify the correct Wi-Fi network name and password.
2. On the printer’s control panel, navigate to the network settings and re-enter the Wi-Fi credentials.

4. Ensure the Printer is on the Correct Network

If you have multiple Wi-Fi networks, ensure your printer is connected to the same network as your computer or mobile device. Mismatched networks prevent communication.

1. On your computer or mobile device, check the currently connected Wi-Fi network.
2. On the printer’s control panel, navigate to the network settings and verify the connected network.
3. If necessary, change the printer’s network to match your computer’s network.

5. Update Printer Firmware

Outdated printer firmware can lead to compatibility issues and connectivity problems. Installing the latest firmware can improve stability.

1. Visit the HP support website for your HP DeskJet 2855e model.
2. Download the latest firmware update.
3. Follow the instructions provided by HP to install the firmware update.

6. Check for Router Firmware Updates

An outdated router firmware may be the cause of connection issues. Updating the router firmware can solve compatibility problems.

1. Access your router’s administration interface through a web browser.
2. Navigate to the firmware update section.
3. Download and install the latest firmware update from your router manufacturer’s website.

7. Disable Firewall or Antivirus Temporarily

Firewall or antivirus software can sometimes block printer communication. Temporarily disabling them can help diagnose the issue.

1. Temporarily disable your computer’s firewall or antivirus software.
2. Attempt to print.
3. If printing works, adjust your firewall or antivirus settings to allow printer communication.
4. Re-enable your firewall or antivirus software.

8. Run the HP Print and Scan Doctor

HP provides a utility to diagnose and fix printing and scanning issues. Using this tool can automate troubleshooting.

1. Download the HP Print and Scan Doctor from the HP support website.
2. Run the utility and follow the on-screen instructions.
3. Allow the utility to diagnose and fix any detected issues.

9. Assign a Static IP Address to the Printer

A dynamic IP address can change, leading to connection problems. Assigning a static IP address can provide a stable connection.

1. Access your router’s administration interface and find the DHCP client list.
2. Locate your printer’s IP address and MAC address.
3. Reserve that IP address for the printer’s MAC address in your router’s DHCP settings.
4. On the printer’s control panel, navigate to the network settings and enter the static IP address, subnet mask, gateway, and DNS server addresses.

10. Check for Interference

Wireless interference from other devices can disrupt the printer’s Wi-Fi connection. Reducing interference can improve connectivity.

1. Move the printer and router away from other electronic devices that may cause interference, such as cordless phones, microwaves, and Bluetooth devices.
2. Change the Wi-Fi channel on your router to a less congested channel.

11. Reinstall the Printer Drivers

Corrupted or outdated printer drivers can cause connectivity problems. Reinstalling the drivers can resolve these issues.

1. Uninstall the printer drivers from your computer.
2. Download the latest printer drivers from the HP support website.
3. Install the drivers following the on-screen instructions.

12. Use WPS (Wi-Fi Protected Setup)

WPS simplifies the Wi-Fi connection process. Using WPS can bypass manual network configuration.

1. Ensure your router supports WPS.
2. Press the WPS button on your router.
3. On the printer’s control panel, navigate to the network settings and select WPS connection.
4. Follow the on-screen instructions.

By following these troubleshooting steps, you should be able to resolve most Wi-Fi connection issues with your HP DeskJet 2855e. If the problem persists, consider contacting HP support for further assistance.
