This guide explains how to complete the HP Deskjet 4155e WiFi Setup, connect the printer using the HP app, install it on Windows and Mac, and troubleshoot common wireless connection problems.
Requirements Before Starting HP DeskJet 4155e WiFi Setup
Before connecting your printer to WiFi, prepare the following items:

Official HP app or compatible printer software
Stable wireless signal
If your printer is new, complete the initial hardware setup first. Remove all packaging materials, connect the power cable, install the ink cartridges, and load paper into the input tray.
Place the printer within a reasonable distance of your router. A weak signal can interrupt the setup process or cause the printer to disconnect later.
The HP DeskJet 4155e generally supports 2.4 GHz WiFi. If your network is not detected, check your router settings and the wireless requirements for your exact printer model.
Method 1: Connect HP DeskJet 4155e to WiFi Using the HP App

Install the application and open it on your computer or mobile device.
Step 2: Turn On the Printer
Connect the HP DeskJet 4155e to a power outlet and press the power button.
Wait until the printer finishes starting up. Check that it has paper and properly installed ink cartridges.
If the printer is new, follow any initial instructions displayed on its control panel or in the HP app.
Step 3: Put the Printer in WiFi Setup Mode
If your printer has not previously been connected to a network, it may already be ready for wireless setup.

Enter the correct WiFi password. Make sure the password is typed accurately because uppercase and lowercase letters are treated differently.
Follow the instructions displayed in the application to transfer your network details to the printer.
Step 6: Complete the Setup
Wait for the application to confirm that the printer has connected successfully.
Once the connection is established, the wireless indicator should display the appropriate connected status for your printer.

How to Change the WiFi Network on HP DeskJet 4155e
If you have purchased a new router, changed your WiFi password, or moved your printer to another location, you may need to connect it to a different wireless network.
First, restore the printer's wireless setup mode using the procedure recommended for the HP DeskJet 4155e.
Open the HP app on your computer or mobile device. Select the option to add or set up a printer and choose your device when it appears.

Troubleshooting HP DeskJet 4155e WiFi Connection Problems
Wireless setup may fail because of incorrect network information, weak signals, incompatible router settings, or temporary software issues. The following solutions can help.
1. Check the WiFi Password
An incorrect password can prevent the printer from joining your network.
Verify the WiFi name and enter the password again. Check for uppercase letters, lowercase letters, numbers, and special characters.
2. Restart the Printer and Router
Turn off the printer and disconnect your router from its power source.
Wait approximately 30 seconds, reconnect the router, and allow it to finish starting up.
Turn on the printer and repeat the setup process through the HP app.
3. Move the Printer Closer to the Router
A weak wireless signal may cause the setup process to fail or the printer to disconnect repeatedly.
Move the HP DeskJet 4155e closer to your router and avoid placing it behind thick walls or near devices that may interfere with the signal.
4. Check Your Router Settings
Make sure your router supports the wireless frequency and security settings required by your printer.
The HP DeskJet 4155e generally uses a 2.4 GHz wireless connection. If your router uses a combined network name for 2.4 GHz and 5 GHz bands, follow HP's instructions for configuring compatible devices.
Also, check whether a guest network or device-isolation setting is preventing the printer from communicating with your computer.
5. Reset the Wireless Settings
If the printer was previously connected to another network, its saved wireless configuration may prevent it from joining the new one.
Reset the wireless settings according to HP's instructions, then open the HP app and repeat the setup process.

Outdated software may cause the printer to remain undetected or experience connection problems.
Visit HP's official support website and check for compatible software or firmware updates for your printer model and operating system.
Install only updates recommended for your device.
7. Check the Printer's Status
If the printer connects to WiFi but does not print, check whether it appears online in your computer's printer settings.
Make sure the correct printer is selected, cancel any stuck print jobs, and send a new test document.
If the issue continues, use the HP app or official HP troubleshooting instructions to identify the cause.
Verify Your HP DeskJet 4155e Wireless Setup
After completing the connection process, take a few moments to verify that everything works properly.
