@leowalz, Welcome to HP Support Community. 

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

It sounds like your HP DeskJet 2755 is having trouble accepting your Wi-Fi password. Here’s are the steps to resolve the problem:

Step 1: Confirm 2.4 GHz and Password Simplicity

• Ensure your Wi-Fi network is 2.4 GHz.
• Try connecting another 2.4 GHz device (like an old phone) using the same password to confirm it's correct.
• If your Wi-Fi password has special characters, temporarily change it to a simple password like 12345678 just for testing.

Step 2: Restore Wi-Fi Setup Mode

• Press and hold the Wireless button 🛜 and the Cancel button ✖️ together for 5 seconds until the Power button starts blinking.
  This resets the printer to Wi-Fi setup mode.

Step 3: Use the HP Smart App

• Install the HP Smart app on your phone or PC.
• Open it, click Add Printer, select Set Up a New Printer, and follow the prompts.
• The app simplifies the process compared to manually entering passwords via the printer panel.

Step 4: Check Router Settings (if nothing else works)

• Log into your router settings.
• Ensure:
  • 2.4 GHz is enabled.
  • Security is set to WPA2 (or WPA2/WPA3 mixed, not WPA3-only).
  • The password does not contain unsupported symbols.

I hope this helps. 

Take care and have a good day.
