Welcome to HP Community

I have gone through your Post and would like to help

Please assign a manual IP Address and check if that helps

1) Obtain the IP address of the printer – You can touch print a Network Configuration page
2) Type the IP address on your web browser to obtain the printer EWS page on your computer.
3) Go to "Network" tab - General - Select "Network protocols" - Select "Enable IPv4 only" (or similar) - Apply the settings.
4) Go to the “Network” tab – Click on “Wireless (802.11) – Then click on “Network address (IPv4)
5) Click Manual IP
6) If you see a Suggest a Manual IP Address button, click Manual IP address, and the Manual IP addresses are automatically filled out for you.
7) If your page does not have a button to suggest a manual IP address, type the IP address, subnet mask, and default gateway using the numbers shown in the report you printed.
