Printer fail to connect to router

@ToyPrint, Welcome to HP Support Community!

I see that you have issues connecting the printer to the network, let us isolate and resolve the issue-

Is there any error message on the printer when you try to connect the printer to the network?

Is your router dual-band enabled i.e., both 2.4GHz and 5GHz?

Did y9ou make any changes to the printer or router recently?

Meanwhile, follow the steps below-

1. From the home screen of your printer control panel, touch the Wireless icon .

2. Touch the Setup icon .

3. Touch Restore Network Defaults or Restore Network Settings, and then touch Yes to confirm your selection.

4. After the default network settings are restored, touch the back arrow, touch Wireless Settings, and then touch Wireless Setup Wizard.

   The printer searches for available networks.

5. Touch the name of your wireless network.

6. If your wireless network does not display in the list of wireless networks, touch Enter New Network Name, and then type the name of your wireless network.

   NOTE: 

   Type the exact network name, including any uppercase and lowercase letters.

7. Type the WEP or WPA key (network password), and then touch Done.

   If you do not know your network password, go to Find Your Wireless WEP, WPA, WPA2 Password..

   Once the printer connects to the wireless network, the blue Wireless light on the control panel turns on solid.

8. If the printer fails to connect, print a Wireless Network Test Report, and then follow any instructions on the report to troubleshoot wireless connectivity problems. For more information, go to Using a Wireless Network Test Report.

Keep me posted for further assistance.
