wifi authentication required

On my dual boot system, Windows10+Ubuntu 22.04, wifi works in Windows, but not in Ubuntu. It keeps telling "authentication required", even though I entered the right Wireless Key.I have a Realtek RTL8111 PCI Express network card. I recently got a new modem ZYXEL, because we changed from DSL to optical fiber.Under tab Security, I tried both WPA 3 personal and WPA 2 personal. I also tried Forget Network and Connect to Hidden Network, but without success. Copy/paste Wireless Key from editor did not work either. Anyone who can help?sudo rm did not work. Wi-Fi settings say: signal strength Good, security WPA 3. I tried both WPA 3 and WPA 2 but I still get the message "Authentication Required"
