I have found this in article in HP Customer Support - Knowledge Base, HP Printers - 'Invalid Passphrase' Error when Using a Wi-Fi Gateway with PMF | HP® Customer Support which fits my symptoms. I just upgraded me Wi-Fi Router to a new Wi-Fi 6 system and I get Invalid WPA Passphrase with the new Wi-Fi system but not with the older Wi-Fi system.
Step 1. The passphrase was entered correctly.
Step 2. Printer has the latest firmware, Firmware Datecode: 20190401
Step 3. Contact support. The printer is out of warranty, so HP wants me to buy Printer Care Pack. This is the only way to get the information that I need.
Question 1. Does the HP LaserJet Pro 200 color MFP M276nw have the Invalid Passphrase problem when connected to a router that use Protected Management Frames (PMF)?
Question 2. If the answer to the above question is yes, does HP plan to release a new firmware to fix this problem?
