Problem changing the Wi-Fi password in Maestro

Maestro has worked without a hitch on both Wi-Fi and wired connections.  I just upgraded the security of my WI-FI and along with that came a more secure password.  Maestro asked for the new password but when I enter it, Maestro doesn’t accept it.  I am looking for a way to erase my Wi-Fi settings so I can start fresh.  I can’t seem to find this covered in the manual.  The Maestro “Choose a Wi-Fi Network” screen has a “forget” option at the bottom but it's grayed out.

 

Thanks,
