Model: KL130
Hardware Version: V2
Firmware Version: 1.0.12



I have three KL130B bulbs. All of them suffer random disconnect issues. They sometimes stay connected for up to a day or two but they all ultimately end up disconnecting.


All three bulbs are:


  • Hardware Version 2.0
  • Firmware Version 1.0.12


I have given them all static IP addresses on my Netgear XR500 router but this has not cured the issue.


I have six Tapo P100 smart plugs and three Tapo L510B smart bulbs and all of these TP-Link devices work flawlessly, so why am I having issues with the KL130B bulbs?


Any help would be much appreciated.

@Bat-n-Ball  Hello, 

Thank you for your detailed post, for bulb unstable issue, you could try some suggestions here: 

1.  Please confirm bulb firmware and kasa APP version are up-to-date 
2. Ensure bulb is connected to main router directly not through AP or extenders, Locate one bulb very close to main router and see if it disconnects 

3. You could try to change a different 2.4Ghz wifi channel on router and see if that helps 

4. Turn off Advanced wireless settings like WiFi optimizing Band steering etc. 

If the above does not work, can you help confirm some information to locate the issue: 
1.  Your network topology ,e.g. Router  Netgear XR500 (in living room) <wireless> KL130 ( in living room) 
2.   MAC address of the bulb (please share via private message)
3.   Can you access the bulb locally when phone is connected to home wifi when the issue happens? What is the Error you got when bulb disconnects? 
4.  Signal strength of the smart Bulb on the APP: Kasa APP, go to device  settings->signal strength ( tap on the Wi-Fi icon/ SSID to see the value of the RSSI)
Thank you.

  1. All bulb firmwares (1.0.12) and Kasa App (V 2.34.0 - Build 1007) versions are up-to-date.
  2. All three bulbs are connected to main router directly and are in the same room as the router i.e., in close proximity.
  3. I have tried 2.4GHz Channel 11, Channel 1 and Channel 6 but all three bulbs eventually disconnect at random times.
  4. Advanced wireless settings like MU-MIMOBEAMFORMING and Wi-Fi multimedia turned off but bulbs still disconnect after a few hours.




  1. Router model: Netgear XR500. Location: in the living room. Bulb proximity: all three bulbs in the same living room, various distances.
  2. MAC addresses to follow in PM.
  3. Can you access the bulb locally when phone is connected to home wifi when the issue happens? No, it has disconnected from the local network and is inaccessible.
  4. Bulb 1 = -48 dBm (4 bars), Bulb 2 = -44dBm (4 bars), Bulb 3 = -60 dBm (3 bars)
