Some customers may find that some of their Kasa devices would randomly auto-reboot (randomly goes off and quickly back on in a sec). This article aims to guide you to get this resolved.
How to determine whether a Kasa device is encountering an auto-reboot, check the below phenomenon:
1) Kasa Device’s LED lights status. When a Kasa plug auto-reboot, the LED light will turn off and then turn on quickly. For a Kasa switch, the Wi-Fi indicator will light up quickly, change to be flashing green, then solid green, then turn off finally. For a Kasa bulb, it will flicker quickly.
2) Electrical appliances connected to Kasa devices. For example, when a Kasa plug auto reboots, the equipment connected to the plug will suddenly lose power and resume immediately. When a Kasa switch auto reboots, the bulb/lamp connected to the switch will suddenly dim or flicker.
Available Solutions----Updated on Apr 30, 2021 Added KP105 (UK) V1 Beta
The developer has provided some beta firmware for certain Kasa models to resolve the auto-reboot, upgrade the firmware of the problematic Kasa devices to this version, monitor a few more days, and check if the auto-reboot is gone
KL110/KL130_V2 : Fixed on firmware 1.0.11 and later firmware.

1) There is a word document in the folder providing detailed instructions to upgrade the Kasa firmware.
2) Please save the downloaded file to the desktop, unzip and open it on the desktop.
3) Please use a Windows computer whenever possible.
For the following suggestions, perform one at a time:
Check and ensure both the Kasa device's firmware and the Kasa app version are up-to-date. If not, update first.
Factory reset the Kasa device by pressing the Reset button for 10 secs, keep it in the factory default state and observe whether it will reboot or not.
Create a new isolated network on your home network and only let Kasa devices connect to this network.
* About isolated network:
1. If your router supports "Guest Network", please turn on "Guest Network" and you can take it as an isolated network.
2. If your network devices support setting “multi SSID” or “VLAN”, please create a new multi SSID/VLAN, and only let the Kasa devices connect to it. It will isolate Kasa devices too.
3. If you have an old router, please connect the old router behind the main router. Assign the new router a different set of IP addresses (like 10.0.10.1) and then assign some smart plugs and switches to the new router.
Note: Do not connect your phone or other Wi-Fi devices to that Guest Wi-Fi/ isolated network that the Kasa devices are connected to, check first if the auto-reboot problem stops or not. As certain device may cause the Kasa device to reboot.
If the issue is gone after you created an isolated network, you could then connect mobile phone and other Wi-Fi devices gradually to see if any device will trigger this reboot issue.
If you’re using a Mesh network, try to disable the "fast roaming" and "beam forming" on the mesh devices.
If your host router is Arris TG1682G, please try connecting the Kasa device to a different model of router or Wi-Fi extender.
If the troubleshooting tips and the beta firmware still don’t resolve the auto-reboot issue, report back by submitting a diagnostic via email with the Subject ‘TP-Link Community- [Forum ID 262328] Kasa devices reboot randomly’, or leave a reply on this thread. In either case, be sure to provide the following information:
- Troubleshooting steps you have taken:
- The detailed network topology/layout (like modem-router-AP. More detailed network topology helps more, like the model of network devices and the network segment, like 192.168.1.0):
- The brand and specific model of the host router:
- The frequency of the auto-reboot:
- Are there other Kasa devices that can work properly without an auto-reboot?
