MacBook Air (2015) can't connect to WiFi

  • I have an AFi-R device, freshly reset to factory defaults and then updated and then configured with a static IP address and a plain WiFi configuration with WPA2 authentication. I can connect to WiFi with my MacBook Pro 2017 and with my iPhone 11, but my older MacBook Air (2015) says the password is incorrect. I tried switching to WPA, but the error is the same. Any ideas how to fix this? Thanks!
