Note:

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

For Smart Bulbs, the bulb will flash 3 times to indicate it’s in Config mode.

For details, you can visit www.tp-link.com and search for 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: Generally, your smartphone will connect to the network automatically, but if it fails to connect, please go to "Settings" to connect. Once connected, please return to the Kasa app, and select "Try Again".

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

If you are unable to find "Local Network" permission in settings, please return to the app and tap "I’ve already given Local Network Permission".

 

Step 4 Be sure to choose the correct model and right wireless network to connect (SSID should be ‘TP-Link_Smart Plug_XXXX’or ‘TP-Link_Smart Bulb_XXXX’. You can check the MAC Address on the device label,  which will contain part of the network name).

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

Step 6 Try using another phone to try again.

Step 7 Some phones prefer to connect to a remembered network profile instead of an unsecured network. In this case, please forget the profile of the remembered network first, but only after confirming that you know that network’s password and can reconnect afterwards.

App Shows: ‘Unable to Find Your Device’ or ‘We couldn’t find Your Kasa Device’

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

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

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.

App Shows: Unable to Connect to Your Wi-Fi Network

 

You may encounter this issue if:

1. You can’t get through the connecting process
2. You are stuck at the last step after selecting/creating the device icon in the Kasa app

Note:

To mitigate network security risks, TP-Link's smart home products do not support captive portal or open Wi-Fi networks.

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

 

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

For smart bulbs, tap "Exit Setup" to exit the setup, go to the Devices page on the Kasa app to see whether you can control the bulb, and 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 select "Restart Setup". Just force close the Kasa app and launch it again, then 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 settings to 8.8.8.8 and 8.8.4.4.

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

Please go to Step 2.

For detailed LED instructions, please refer to the product’s User Guide.

You can go to www.tp-link.com and search for your smart device’s model number, then click on Support. From here you will find product documentation including 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. 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 instructions below on how to forget the router’s Wi-Fi and connect again to confirm the password.

How to remove existing wireless network profile on Android&iPhone

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

Step 4 Try using another phone and try again.

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 unable to connect to the Wi-Fi network, you can try temporarily disabling the 5GHz Wi-Fi band on your router, then try again.

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

If the 5GHz band cannot be disabled, try moving the router or smart device further away from each other to ensure the smart device connects to a 2.4GHz Wi-Fi network. This is because 2.4GHz Wi-Fi typically provides further range than 5GHz.

What To Do If You Failed to Set the Device’s Name or Icon

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 Ensure the Wi-Fi LED is solid Green or Blue, indicating the network connection has been established. Force close the Kasa app and launch it again, then wait a few seconds to verify whether the device is working.

For the smart bulbs, select "Exit Setup" to exit the setup, then go to the Devices page on the Kasa app to verify 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 for further troubleshooting.

Step 3 Try a Simple name / Try Icon from Kasa app, and not from your Album/Gallery.

Step 4 Try using another phone.

Step 5 Reset the Kasa device and try again.
