Wi-Fi name and password reset? Devices won’t connect, still looking for custom name

Our power went off and on all day due to the tropical storm. Power resumed but none of my devices reconnected so I unplugged/replugged all network devices. My Smarthome Manager shows the network is active but the custom Wi-Fi name doesn’t appear on any of my previously connected devices.  I’ve been able to use the original name/pw to connect my phone but that doesn’t make sense why the custom name still shows connect in home manager. My home is pretty automated so there are at least 30 devices I need to connect. Help!!
