Welcome to HP Forums, 

This is a great place to get support, find answers and tips, 

Thank you for posting your query, I'll be more than glad to help you out 🙂 


As I understand printer isn't recognizing wifi connections,

Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details: 

Have you attempted a network default to resolve the issue?


While you respond to that, here's what you need to do:

To restore network settings to default settings

Press the Wireless button and the Cancel button from the printer control panel at the same time, and then hold them for three seconds.

The network will need to be reconfigured afterwards. Then the user name will be admin and the password is left blank. 


If the issue persists, please try turning off mac filtering by accessing the EWS page of the printer and check if that works.


Keep me posted,

If the information I've provided was helpful,

Good Luck.
