I can't figure out why all of a sudden I'm not connected from my printer to my computer via wi-fi

Hi @Norgemusiker,

Welcome to the HP Support Community. 

I understand that you are facing connectivity issues. I’d like to help!

Make sure, your printer and your device are on the same network as 2.4GHZ only. 

Is it a private (Home network) or a public Wi-Fi connection? Wi-Fi direct? Or Hotspot?

Check for network and connection issues if you cannot print or scan with a wireless HP printer.

Restart devices

• Restart your computer or mobile device, printer, and router to clear any error states.
• Disconnect your computer or mobile device from the network name (SSID), and then reconnect it to the same network name your printer is connected to.
• If the printer is available and has a ready status, the issue is resolved. You do not need to continue troubleshooting.
• Press the Power button to turn off the printer. If the printer does not turn off, disconnect the power cord from the printer and from the power source.
• Turn off the computer or mobile device that the printer was set up with.
• Restart the router.
• Reconnect the power cord to the printer and to a wall outlet.

Note: HP recommends plugging the printer directly into a wall outlet.

• Turn on the computer or mobile device.
• Check the connection to make sure the same network is used by the printer and the device.
• Computer or mobile device: Open the list of available networks and make sure it is connected to the correct network.
• Printer: Check the Wireless light on the control panel. If it is solid blue the printer is connected.
