Why Is My HP Officejet Pro 9025 Not Connecting to the New WiFi Device?

Today I was trying to connect my HP Officejet Pro 9025 printer to the new ATT Fiber Internet connection. But it fails every time. It says the printer 9025 connected to the Wi-Fi network but there is no internet connection available while printing. Please help me to resolve this.

Thank you, Mister, for writing your query. You need to first restore the network settings. Next, you are supposed to establish the connection with the help of the wireless setup wizard option from the control panel. You can also download, install, and use the HP Smart app for Windows to do the printer setup easily and quickly.
