@Elevate,

Couple of things to try:

If you already tried to set up a device and failed, forget the network from your list of known networks

Disable private addressing on your phones settings, as it may be preventing you from reconnecting to the device.

When you are told to manually connect to the network, try forgetting or turning off auto connect for your regular network, your device may be automatically switching because the plugs wi-fi cannot provide an internet connection.

I would also definitely reset the plugs back to factory defaults after a failed installation. 

When going through the setup, are there any other errors or notifications that could give a clue. For example, do your phone settings indicate an issue when reconnecting manually to the plug, such as a 'failure to get IP address'?

Lastly, what devices and OS are you using to try and connect the devices? What router an network are you trying to connect to?

  @gc22,

When you are resetting the KL110, 3 blinks means that a soft reset has been completed - indicating that the network settings have been reset, but the device settings remain. First try to complete a factory reset of the device, which is done by restarting the device 10 times and then the device will also blink 5 times. Try to then set up the device from the app.

FAQ: Resetting a Bulb

Please take note of the fact that there must be a slight delay in between the restarts to allow the device to initially boot. It is recommended to wait 1 second between toggles.

If you are still unable to see the SSID being broadcast by the plug, I would recommend downloading a Wi-Fi scanning app to determine if the Wi-Fi is simply not appearing in your list of devices.

The KL110 also offers another method of setup that may allow you to initially connect the device to the network and update the firmware. You might try to use the Alexa Frustration Free Setup and then add the device to your Kasa Account. More information about the setup methods can be found in the user guide here: KL110 User Guide
