HP Printer won't connect to router updated from WPA to WPA2

[Teazel]

I recently updated my (Hitron) home router settings from WPA to WPA2, for improved security.

I anticipated no problems with my HP Officejet Pro 8600 Plus printer as (page 228) of its operating manual confirms "...the printer supports many common types of network authentication, including WEP, WPA, and WPA2 ...".

I was very disappointed to find that this statement in the HP manual is simply not true.  After many hours of fruitless effort I discovered that the printer contains settings that look for WPA-PSK authentication and AES/TKIP settings on the router (as shown on the HP Network Configuration report page), but it is not possible to change these internal settings in the printer to accept WPA2 authentication in the router.

After numerous web searches I found others have found the same or a similar problem with, apparently, no effective solution from HP.  The only HP input I could find was generic, time consuming (and totally ineffective) troubleshooting procedures that provided no solution at all. Among other things I: updated the firmware in the printer, (repeatedly) restored the printer to network default settings, performed network power drains in all connected devices, and restarted the devices in the correct order, with exactly the same result every time... being total failure to connect with the router.  Running the Wireless Network Test Results report repeatedly displayed the problem as being the "No filtering" Fail, due supposedly to activated MAC address filtering on the router. That was a completely misleading and meaningless result as no MAC address filtering of any kind is activated on the router.

I attempted to use HP's printer software Utilities to get the  printer to accept WPA2 settings.  The Network Setup process/page correctly identified network security as WPA2 (AES), and the software then proceeded to update the printer's internal settings, only to fail, again with the nonsense indication that the issue "May be MAC Address filtering enabled on your wireless router".

No. The issue is that the settings in the printer to find WPA authentication settings on the router cannot  be changed, so HP's assertion  in its operating manual that it will work fine with WPA2 is a deceit.  My choices, apparently, are to lower my network security to WPA, to have a USB cable trailing across my office, or to throw this expensive piece of equipment into the landfill.

Very disappointed in HP's failure to even be truthful in its product documentation, let alone rectify its product defects.

After reading a dozen of posts from 2013 to 2020, I can't see any resolution for it. Please try the following way

Hope this helps.

Thanks for your efforts to help and your reply.  I followed the link in your note  but I have a Windows computer, not a Mac.  And the procedures described for the HP Printer I have tried repeatedly, with no result.

I did get a response last evening to my initial note from an HP person, providing a link to arrange for HP technicians to call me and assist with a solution. I was going to follow that up this morning but now I see that response has disappeared from this string.  Even more disappointed in HP now!
