TopGreener Dimmer Switch Not Connecting to WiFi


Does someone know the button combination I need to press in order for a TGWF500D dimmer switch to connect to my WiFi network? I’ve already configured it with the SSID and password in Tasmota, however it didn’t log into the network after it rebooted. Once powered up I have a flashing green light by the WiFi label at the bottom left of the switch. The closest AP is 2.4 GHz.

Thanks in advance for any help that can be provided.
