How to resolve common problems when setting up the Kasa smart device (Plug/Bulb)

Released On: 2018-11-05 12:19:52Last update time: a week ago

Our Kasa app is designed to provide an easy step-by-step process to set up your new smart device. However, there may be instances where issues come up during the installation. This guide will try and provide steps to try in order to resolve your issue.


Case 1 

  • Go into the “Settings > Wi-Fi” menu of your smartphone for Android or "Settings > Wi-Fi > Choose a network" for iOS, manually connect to the smart device's network. Open Kasa and select the option that you are manually connected to the smart device located on the bottom of the setup screen
  • Make certain you choose the correct smart device to connect to. The last four characters of the MAC address are also apart of the network name of the smart device.
  • Disable any VPN connection that your phone may be using during the setup.
  • Perform a factory default on the smart device and repeat the process.
  • If your Apple device is running iOS 14, check the app permission to allow local network access


Case 2

  • Make sure the smart device is not connecting back to your home Wi-Fi network. If so, connect back to the TP-Link Wi-Fi network.
  • Reinstall the Kasa app on your smartphone.


Case 3

  • When on the screen where you join the smart device to the network. The wireless network name you see above the wireless password box should be the one you normally connect to in order to receive internet, if not, select the link below to choose a different network name.
  • The wireless signal should be at least two bars, if it is one bar, move the device closer for setup.
  • If the router’s SSID is hidden, please choose “manually setup my Wi-Fi” to input SSID and password.


Case 4

  • Wait 15 seconds then check LED status. If the smart device's LED indicates it is connected to the network or if the bulb blinks several times, do not select the option to start over. Sign out and back into the Kasa app and wait a few minutes to see whether the device is working.
  • Check to see if your phone is now connected back to your home Wi-Fi. If not, connect back, and go back to Kasa.
  • Verify that the wireless password being used is correct. Going into your phone Settings > Wi-Fi menu. Forget the wireless network that you are trying to connect the smart device to, and then reconnect. When the phone asks for the wireless password, use the same password that you tried in Kasa. Delete the password that exists in the box and enter the wireless password for your network again.

Hallo, mein Kommentar ist anscheinend weg :-(


ich versuche verzweifelt meine beiden HS100 WLAN Steckdosen zu aktivieren. In der App bekomme ich die Installation mit dem IPad hin, kann die Geräte auch soweit steuern. 
damit ich diese aber mit der Alexa nutzen kann benötige ich die Fernsteuerung. Diese lässt sich mit dem Fehler "TCP connect Fail" aber nicht aktivieren. 
ebenso kann ich das Firmware Update nicht installieren. 

kann mir jemand helfen? auch weiß mir nicht mehr weiter. Hab die Geräte jetzt schon mehrfach wieder gelöscht, die Kasa App neu installiert. 

vielen Dank im Voraus! 

Hello, I just recently purchased a smart plug, it worka fine for me but does not work for my wife. It recognizes what she is saying but says the action is not available. 

Thank you so much I was also connected with my phone and played the Minecraft mod apk game


I had to set my Orbi router to use "automatic" for the 2.4G channel after I upgraded the Orbi firmware, even though my smart plugs had been connected before the Orbi FW upgrade. But after the upgrade, they refused to connect with the 2.4G channel manually set. After I switched the router setting to "automatic", the plugs connected with no problem.




Very nice article
