Hi @Roof14,

Welcome to the HP Support Community

I'd like to help!

I understand you changed the wifi password and are trying to connect the printer to the network.

Connect the printer using the HP Smart app

Restore Wi-Fi setup mode on the printer, and then use HP Smart to connect the printer to your Wi-Fi network.

Restore Wi-Fi setup mode on the printer

Prepare a printer for a Wi-Fi connection by restoring Wi-Fi setup mode.

When the settings are restored, the printer enters Wi-Fi setup mode for about two hours, making it discoverable during the HP software installation.

Envy 6000, 6000e, 6400e, ENVY Pro 6400, DeskJet Plus IA 6000, 6400, and Tango printers: Press and hold the Wireless button on the back of the printer for five seconds until the Status light flashes (blue or purple depending on the model).

Go to Restore Wi-Fi setup mode on your HP printer for additional information and button presses for more printer models.

Install HP Smart

Install the HP Smart app on your computer or mobile device.

Do the following if you are setting up the printer on a Wi-Fi network.

Place the printer and the computer or mobile device near the Wi-Fi router.

Turn on Wi-Fi on your computer or mobile device and connect to your network. If the computer is connected to the network with an Ethernet cable, temporarily disconnect the cable and use the Wi-Fi connection during the setup.

Enable Bluetooth on the computer or mobile device so that HP Smart can detect the printer during the setup.

After installing HP Smart for iOS and Android, enable the mobile device location service and allow the app to use your location to detect the printer and offer solutions during setup.

Download the HP Smart app from 123.hp.com (Android, Apple iOS, iPadOS), HP Smart - Microsoft Store (Windows), or HP Smart - Mac App Store (macOS).

If you are prompted to sign in with Microsoft to use the app across devices, you can sign in or click No, thanks to continue.​

NOTE:

Disconnect from a Virtual Private Network (VPN) connection before downloading.

If you are setting up HP Smart for the first time, you must create or sign in to an HP account to access all printer functions.

In HP Smart, click Add Printer or the plus sign to search for the printer, and then follow the instructions to complete the setup.
