Hello @Curmudgeon10 

Please follow APP instructions to set up the smart device, when app guides to connect to Kasa_Smart Switch_ XX SSID (smart  device default SSID is an open Wi-Fi without Internet access, it will be gone after smart device successfully connected to router's Wi-Fi)

• iOS: Go to the Settings page, click on the Wi-Fi  to connect to the Smart device’s Wi-Fi manually, then go back to app to continue set up

Android: Android phone will look for smart device automatically, if not or could not find  device,  manually connect to Smart device's Wi-Fi, go back to APP and continue set up.

• Turn off VPN

If any error occurs, please try some instructions here: What should I do if I fail to configure the Kasa device?

Can I know the model and Android or IOS version of your phone if concern persists,thank you.
