Hi @nikmc2191,

Welcome to the HP Support Community.
 

Thank you for posting your query. I will be glad to help you.

I can understand how annoying it can be when your HP DeskJet 4155e suddenly loses internet connection, especially when everything else seems fine. Let’s walk through the steps to get your printer reconnected quickly and reliably.

Step-by-Step Fix: Reconnect HP DeskJet 4155e to Wi-Fi

1. Reset the Printer’s Network Settings

This clears any old Wi-Fi info and puts the printer in setup mode:

• Turn on the printer.
• Press and hold the Wireless button (looks like a Wi-Fi icon) for 5 seconds until the light starts blinking.
• Then, press and hold the Cancel button (red X) for 5 seconds.
• The wireless light will stop blinking once the reset is complete.

2. Reconnect Using HP Smart App

• Download the HP Smart app: HP Smart
• Open the app and follow the prompts to add your printer.
• Make sure your phone or PC is on the same Wi-Fi network you want the printer to join.

3. If You Changed Your Router or Network Name

HP has a dedicated guide for reconnecting after router changes: 👉 HP printers - Wi-Fi connection is lost after router or network settings change | HP® Support

This includes:

• Use Wi-Fi Protected Setup (WPS) if your router supports it.
• Restoring Wi-Fi Setup Mode if the printer isn’t found.
• Printing a Wireless Network Test Report to diagnose issues.

I hope this helps.

Take care and have an amazing day!
