Hi @Lex-rn,

Welcome to HP Support Community.

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

It seems like your HP DeskJet 4155e printer is having trouble connecting to the new Wi-Fi network. Here are some steps to troubleshoot and hopefully resolve the issue.

Reset Printer's Network Settings:

• Reset the printer’s network settings to clear any old settings.
  • Press and hold the Wi-Fi button on the printer for about 5 seconds until the light blinks.
  • Wait for the light to start blinking quickly, which indicates the printer is in setup mode.

Check Wi-Fi Network:

• Make sure you are connecting to the correct network and that your iPhone is connected to the same Wi-Fi network.
• Ensure the Wi-Fi network you’re connecting to is using the 2.4 GHz band (if your router supports both 2.4 GHz and 5 GHz networks), as many printers have trouble connecting to 5 GHz networks.

Enter Correct Network Password:

• Double-check the Wi-Fi password you are entering. It's easy to mistype, especially for special characters or capital letters.
• Make sure your iPhone is also connected to the same Wi-Fi network you're trying to connect the printer to.

Use HP Smart App:

• Download and install the HP Smart App from the App Store if you haven’t already.
• Open the app and add the printer by following the instructions in the app to connect your printer to the Wi-Fi network. The app might help bypass the password issue by using automatic setup methods.

Check the "E" Error on the Printer Screen:

• The “E” might indicate a communication issue or a setup error.
  • After resetting the network settings on the printer, the error should clear once the printer is successfully connected to the network.

Reboot Router:

• Sometimes, a router reboot helps resolve any connectivity issues. Turn off the router, wait for about 30 seconds, and then turn it back on.

Update Printer Firmware:

• If you have successfully connected using the HP Smart App, check for any firmware updates in the app that could resolve any connectivity bugs.

I hope this helps.

Take care and have a good day.
