Hello, I am using HP Smart to setup a new printer (HP ENVY Inspire 7921e All-in-One Printer) when I get to the wifi connection setup I am getting the error code -9 and the message Unable to connect to Wi-Fi network.
I already tried the turn off and on again on the printer and router.

Hi @fdhshdyjj,
Welcome to the HP Support Community
I understand you are facing a Wi- Fi issue with your HP ENVY Inspire 7921e All-in-One Printer. Not to worry I will help you to get a resolution to resolve the issue.
Let's perform a power drain:
- With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.
- Remove USB cable, if present.
- Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.
- Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord (This is important) and then plug back the power cord to the printer.
- Turn on the printer and wait till warm-up period finishes and the printer is idle
