Troubleshooting Guide: My HP DeskJet 4155e Printer Won’t Connect to WiFi

If your HP DeskJet 4155e printer won’t connect to Wi-Fi, you’re not alone. Wi-Fi connectivity issues are common with wireless printers and can be frustrating. Fortunately, there are multiple troubleshooting steps you can take to resolve the issue and how to connect hp deskjet 4155e to wifi. This guide walks you through the possible causes of connectivity issues and solutions to help restore your printer’s Wi-Fi connection.

Why Your HP DeskJet 4155e May Not Connect to Wi-Fi

Before diving into troubleshooting steps, it’s helpful to understand some common causes of Wi-Fi connection issues with the HP DeskJet 4155e:

1. Weak Wi-Fi Signal: If the printer is too far from the router or there is interference from other electronic devices, the connection may be unstable or fail entirely.
2. Incorrect Network Settings: Entering the wrong Wi-Fi password or connecting to the wrong network can prevent a successful connection.
3. Firmware Outdated: Outdated printer firmware can lead to compatibility issues with newer routers or devices.
4. HP Smart App Issues: Sometimes, the HP Smart app may fail to detect the printer or experience connection problems.
5. Network Configuration Issues: Problems with the router settings, such as MAC filtering or disabled 2.4 GHz band, can prevent the printer from connecting.

With these potential causes in mind, let’s go through some detailed troubleshooting steps.

Step 1: Verify Basic Printer and Network Setup

Check Printer Power and Status

1. Ensure the Printer is Powered On: Make sure the printer’s power button is lit. If it’s not on, press the power button to turn it on.
2. Check the Wireless Light: If the wireless light is blinking, it indicates that the printer is attempting to connect to a network.

Ensure Wi-Fi is Enabled

1. Press and hold the Wireless button on the printer for three seconds until it starts blinking. This will turn on the Wi-Fi setup mode.
2. Make sure you initiate the Wi-Fi setup within two hours to avoid the printer timing out of setup mode.

Verify Network Connection Requirements

1. Move Closer to the Router: Ensure the printer is within a reasonable distance (ideally within 30 feet) of your Wi-Fi router.
2. Avoid Physical Obstructions: Minimize any physical barriers like walls, metal objects, and electronic devices between the printer and the router to ensure a stable connection.

Step 2: Use the HP Smart App to Connect Your Printer to Wi-Fi

The HP Smart app is an easy way to connect your printer to Wi-Fi.

Set Up Wi-Fi Using the HP Smart App

1. Download the HP Smart App:
   • On a mobile device, download the app from the App Store (iOS) or Google Play Store (Android).
   • On a desktop, go to 123.hp.com to download the HP Smart app.
2. Enable Bluetooth and Location Services:
   • Bluetooth and location services should be enabled to allow the app to detect your printer.
3. Connect to Wi-Fi:
   • Open the HP Smart app, tap Add Printer, and select the HP DeskJet 4155e from the list.
   • Select your Wi-Fi network and enter the network password when prompted.
4. Wait for Confirmation: If the connection is successful, the wireless light on the printer will become solid. If the app fails to connect the printer, try repeating the process.

Step 3: Check Your Wi-Fi Network and Router Settings

Ensure Your Router is Broadcasting a 2.4 GHz Network

The HP DeskJet 4155e typically connects to a 2.4 GHz network. If your router has both 2.4 GHz and 5 GHz bands, ensure the 2.4 GHz band is enabled.

1. Access Router Settings:
   • Log in to your router’s web interface (typically by entering your router’s IP address in a web browser).
   • Navigate to wireless settings to confirm that the 2.4 GHz network is enabled.
2. SSID Visibility: Ensure your 2.4 GHz network is set to “visible” rather than “hidden” to allow the printer to detect it.

Check for MAC Address Filtering

MAC address filtering is a security feature that can prevent unauthorized devices from connecting to a network.

1. In your router settings, go to the MAC Filtering section.
2. If MAC filtering is enabled, either disable it temporarily or add your printer’s MAC address to the list of allowed devices.

Step 4: Update Printer Firmware

Outdated firmware can cause compatibility issues with routers and lead to Wi-Fi connection problems. Updating the firmware can improve connectivity.

Steps to Update HP DeskJet 4155e Firmware

1. Open the HP Smart app and navigate to Printer Settings.
2. Select Advanced Settings or Printer Maintenance.
3. If an update is available, follow the on-screen instructions to install it.

After updating the firmware, try connecting the printer to Wi-Fi again.

Step 5: Try the WPS (Wi-Fi Protected Setup) Method

If you’re unable to connect through the HP Smart app, you can try the WPS button method if your router supports it.

1. Activate WPS on Your Router:
   • Locate the WPS button on your router and press it. The WPS light will start blinking.
2. Press the Wireless Button on the Printer:
   • Press and hold the Wireless button on the HP DeskJet 4155e for three seconds until it begins to blink.
3. Connect Automatically:
   • The printer should automatically connect to the Wi-Fi network. Once connected, the wireless light on the printer should be solid.

Step 6: Restart the Printer and Router

Sometimes, restarting the devices can resolve connectivity issues.

1. Power Cycle the Printer:
   • Turn off the printer and unplug it from the power source for about 30 seconds.
   • Plug the printer back in and turn it on.
2. Restart the Router:
   • Unplug the router from the power source for about 30 seconds and then plug it back in.
   • Wait for the router to fully restart before attempting to reconnect the printer.

Step 7: Reset Network Settings on the Printer

Resetting the network settings on the HP DeskJet 4155e can help clear any previous network configurations that might be causing issues.

1. Reset Network Settings:
   • Press and hold the Wireless and Cancel buttons on the printer simultaneously for five seconds. The printer’s wireless light will start blinking, indicating that network settings have been reset.
2. Reconfigure the Printer on Wi-Fi:
   • Open the HP Smart app or follow the WPS method to set up the Wi-Fi connection from scratch.

Step 8: Troubleshoot with the HP Print and Scan Doctor

HP offers a free tool called HP Print and Scan Doctor, which can automatically diagnose and fix many common printing and connectivity issues.

1. Download HP Print and Scan Doctor:
   • Visit the HP support website and download the tool onto your Windows computer.
2. Run the Tool:
   • Open HP Print and Scan Doctor, select your printer, and follow the prompts to diagnose any Wi-Fi connection issues.

Step 9: Advanced Troubleshooting for Network Issues

If you’ve followed the above steps and still cannot connect, there might be network-related issues requiring advanced troubleshooting.

Check for IP Address Conflicts

An IP address conflict can prevent the printer from connecting to Wi-Fi.

1. Assign a Static IP Address:
   • In the HP Smart app or your router settings, assign a static IP address to your printer to avoid conflicts with other devices.

Verify Firewall Settings

Firewalls and antivirus software on your computer or router may block the printer from connecting.

1. Temporarily Disable Firewall:
   • Disable any firewall settings and see if the printer connects.
2. Allow Printer through Firewall:
   • If disabling the firewall allows the printer to connect, add the printer as an exception.

Step 10: Contact HP Support

If none of the steps above resolve the issue, you may need assistance from HP’s customer support team. They can offer more specialized troubleshooting and guide you through any complex connectivity issues specific to your printer or network setup.
