Hi All
suddently my printer HPDeskjet 3055A start light blinking on wifi button and became not connected. I try to reconfigure the printer through usb and HP assistant tools , I can detect the usb printer, printing too. But converting the usb printer to wifi result an error : Wifi password incorrect. The key configured on your printer is not the same as your wifi connexion .
I tried half reset and full reset too ! Nada ! 😞
I think we cannot write on the memory flash printer to store the new wifi config !
Thanks for your help !

Hi @YO915
Welcome to HP Support Community.
Thank you for posting your query, I will be glad to help you.
If your HP DeskJet 3055A printer is having issues connecting to Wi-Fi and you’re encountering the “WiFi password incorrect” error, here are some steps to troubleshoot and hopefully resolve the issue:
1. Check Wi-Fi Password
- Double-check the Password: Ensure that you’re entering the correct Wi-Fi password. It’s case-sensitive, so verify there are no typos or extra spaces.
2. Reset Network Settings
- Power On: Ensure the printer is on.
- Network Reset:
- Press and hold the Wireless button and the Cancel button (the red X) at the same time for about 5 seconds.
- This will reset the network settings and you will need to reconnect to your Wi-Fi.
3. Use HP Smart App for Setup
- If you haven’t already, try using the HP Smart app:
- Download the HP Smart app from the HP website.
- Open the app and select “Add a printer”.
- Follow the on-screen instructions to set up the printer wirelessly.
4. Temporary USB Connection
- If the HP Smart app doesn’t work, you can try connecting the printer temporarily via USB:
- Connect the printer to your computer using a USB cable.
- Open the HP Smart app or HP Printer Assistant.
- Try setting up the Wi-Fi connection again through the app.
5. Ensure Correct Wireless Configuration
- Make sure your printer is within range of the Wi-Fi router and that there are no obstructions.
- Check if there are any settings on your router that could block the printer (like MAC address filtering).
6. Firmware Update
- If the printer is connected via USB, check for any firmware updates through the HP software. Sometimes updates can resolve connectivity issues.
7. Factory Reset the Printer
- If none of the above works, you might consider a factory reset:
- Turn off the printer and unplug it from the power source.
- Wait for about 60 seconds.
- Plug it back in and turn it on.
- Check the printer manual for specific instructions to perform a factory reset if available.
I hope this helps.
Take care and have a good day.
