The Kasa app will guide you step-by-step during the initial configuration, however, you may not be able to get through all the steps due to some interference. This FAQ will tell you what to do when you get stuck in a step.

Note:

1. Ensure download the correct App, Get the Kasa Smart app from the App Store or Google Play.

2. Make sure that the model number of the product being chosen during the configuration is correct.

  1. Unable to Connect to Your Smart device Wi-Fi
  2. Cannot see the Kasa device’s Wi-Fi on the Phone

Note:

For Smart Plug/Switch, the Wi-Fi light blinks orange and green means it’s in Config mode.

For Smart Bulb, it will be flashing 3 times to show it’s in Config mode.

For details, you can go to www.tp-link.com and search your smart device’s model number, click on Support, then you will see the User Guide.

Step 2 iOS: Go to "Settings" to connect the Wi-Fi manually;

Android: It can connect to the network automatically, but if it fails to connect, please go to "Settings" to connect to it. Once it’s connected, please go back to the Kasa app and click on "Try Again".

Step 3 Click on "Settings" on your phone and find our APP on the list, then enable the "Local Network" option. Reopen our APP and try again.

If can't find "Local Network" permission, please go back to APP and click "I’ve already given Local Network Permission".

Step 4 Make certain you choose the correct model and right wireless network to connect, which SSID should be‘TP-Link_Smart Plug_XXXX’or ‘TP-Link_Smart Bulb_XXXX’. (check the MAC Address on the label which is in line with some part of the network name).

Step 5 Make sure there is no VPN or VPN software like Lookout, AdGuard on the phone. If there is a VPN running, turn off the VPN on the phone.

Step 6 Use another phone to try again.

Step 7 Some phones prefer to connect to a remembered network instead of an unsecured network, in this case, please forget the profile of the remembered network first.

Case 3 ‘Unable to Find Your Device’/ ‘We couldn’t find this Kasa device’

The App can’t find the smart devices with Bluetooth.

Step 1 Make sure you selected the right model number for your smart device and powered on it.

Step 2 Power off, then on (or press the restart button) your smart device to restart it.

Step 3 Move your phone or tablet closer to the smart device.

Step 4 Turn your phone's or tablet's Bluetooth off and back on, then try again.

Step 5 If the issue persists, please reset your smart device and reboot your phone, then try again.

Case 4 Unable to Connect to Your Wi-Fi Network

Note:

To avoid risks, TP-Link's smart home products do not support portal or open Wi-Fi.

A captive portal is a webpage that the user of a public network is required to view and interact with before they can access the network. Typically, users are required to fill out authentication information in order to connect.

  1. Can’t get through the connecting process
  2. Stuck at the last step after creating the icon

Step 1 Wait for 15 seconds and then check the LED status. (Only for smart plug/switch)

For the smart bulb, click "Exit Setup" to exit setup, go to the Devices page on the Kasa app to see whether you can control the bulb, if yes, go to the Device Settings page to change the device name and icon. If not, please go to Step 2.

  1. Wi-Fi LED is solid Green or Blue

If the Wi-Fi LED is solid Green or Blue, indicating the network connection has been established, please DO NOT click on "Restart Setup". Just force to close Kasa APP and launch it again, wait a few more seconds to see whether the device is working.

You can change the device name and icon on the device settings page later if the Kasa device is configured successfully.

If the Wi-Fi LED is solid Green or Blue, but you can't find the Kasa device on the "Devices" page, please contact your router support to check if it has enabled "AP Isolation/Client Isolation" function and change the router’s DNS to 8.8.8.8 and 8.8.4.4.

  1. Wi-Fi LED is NOT solid Green or Blue

Please go to Step 2.

For the detailed LED explanations, you can refer to the User Guide.

You can go to www.tp-link.com and search your smart device’s model number, click on Support, then you will see the User Guide.

Step 2 Ensure the router’s Wi-Fi signal strength is strong, and your phone is connected to the same home network as the Kasa device now. If not, please move your device closer to the router.

Step 3 Confirm the Wi-Fi password of your router. Configure the Kasa device again if the Wi-Fi password you typed in is wrong.

You can refer to the instruction below to forget the router’s Wi-Fi and connect again to confirm the password.

The password length can’t exceed 64 characters and confirm the password does not contain characters such as single and double-quotes.

Step 4 Change another phone to have a try.

Step 5 Contact your router’s support and switch the Wi-Fi encryption method to WPA2+AES.

Change the wireless channel to 1, 6, or 11 and channel width to 20MHz of the router and configure the smart device again.

If still can not connect to the wifi network, you may try to turn off the 5G on your wifi router to have a try.

Step 6 For dual-band or Mesh router, use a different SSID (Wi-Fi name) for the 5Ghz band from 2.4Ghz or temporarily turn off the 5Ghz band.

If 5ghz can not be disabled, try moving the router or smart device far away from each other to make sure the smart device connects to a 2.4Ghz wifi network. This is because 2.4Ghz wifi typically has a better range than 5Ghz.

Case 5 Failed to create name/ icon for the device

Step 1 Ensure the router’s Wi-Fi signal strength is strong, and your phone is connected to the same home network as the Kasa device now.

Step 2 If the Wi-Fi LED is solid Green or Blue, indicating the network connection has been established. Just force to close Kasa APP and launch it again, wait a few more seconds to see whether the device is working.

For the smart bulb, click "Exit Setup" to exit setup, go to the Devices page on the Kasa APP to see whether you can control the bulb.

You can change the device name and icon on the device settings page later if the Kasa device is configured successfully.

In other situations, please refer to Case 4 to do further troubleshooting.

Step 3 Try a Simple name / Try Icon from Kasa APP, not choose from Album

Step 4 Change another phone to have a try.

Step 5 Reset the Kasa device and try again.
