Printer Disabled its own WiFi connection, can't re-enable

[themichaeltoy]

Two days ago my printer was working fine. The network configuration is: The printer is connected to my WiFi router via WiFi, my computer is connected to the WiFi router with an ethernet cable. This computer does NOT have a WiFi radio in it.

This morning, the printer no longer works.

the "HP Networking Configuration Page" shows the 802.11 Wireless connection as off, with this message:

"You cannot use the device's wireless function because it has been disabled. For more information, contact your network administrator or the person who set up the device."

I am both of those people, and I did nothing to disable WiFi.

The printer now will only speak to a direct ethernet connection, a USB port, or a "WiFi Direct" connection, none of these connection methods will let me speak from my computer to the printer.

I don't know how or why my connection to my WiFi router was disabled, but I need to know how to re-enable it.

HP was apparently really busy and unable to get back to me to provide support, but by spending pretty much an entire day spread over a few days, I was finally able to re-enable the WiFi. Leaving the steps here in case anyone else runs into this problem:

Here are the steps:

1. "Remove" non working version of print from my Printer List
2. Pick up the printer and move it somewhere I can connect it with a wire.
3. While wired. install HP Smart app, use to to add the printer
4. Run the HP Smart App / Printer Settings / Advanced / Network / Wireless 802.11 
5. Enable and connect to WiFi
6. Exit the App
7. Remove the Printer
8. Unplug the Ethernet and move it back to where it belongs
9. Turn it on, Run HP Smart App and Add Printer again
