Hi @Naren0504831 

Welcome to the HP Support Community! We're here to help you get back up and running.

Not to worry, I'll do my best to reconnect the printer to your wireless network.

Let us try to restore the printer to the default network settings, and then use HP Smart to connect the printer to your Wi-Fi network.

Step 1:

Restore network default settings on the printer, to do that - 

Reset the wireless settings to make sure the connection completes successfully.

Make sure the printer is powered on.

Press and hold the Power button .

While holding down the Power button, press the Start Copy Black button two times, and then press the Cancel button three times.

Release the Power button .

The wireless light next to the wireless button blinks. Repeat these steps if the wireless light does not blink.

Continue to the next step to install the software. You have approximately 20 minutes to complete the software setup using the HP Auto Wireless Connect feature.

Step 2:

Uninstall and re-install the HP Smart app on your computer/mobile device.

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).

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

Also make sure you are trying to connect to the 2.4GHz network, because your printer model does not support the 5GHz network.
