Hi @MrFelter,

Welcome to the HP Support Community. 

I'd like to help!

Reset your printer back to Network Defaults. 

Then run the Wireless Setup Wizard to connect.  Both can be accessed from the front panel or computer.  If no front panel for configuration, you must use your Printer USB cable to connect.  You can also try the WPS method if your router/printer supports this only if the Wizard or Printer USB cable is not available.  Read your User Guide for info.

* Wireless printers only connect to the 2.4G band in your router.  The router must have the 2.4G SSID band enabled with a different SSID name than the 5.0G SSID band in your router.

* Set router to a fixed wireless channel like 1, 6 or 11, never ‘auto’.  Try channel 1 first then the others one at a time. 

* Make sure the printer and router are at least 5 feet apart. 

* Make sure IPv6 is disabled in the printer.
