Model: HS200  
Hardware Version:
Firmware Version:

Starting from a few days ago, my Google Home can't no longer control my KASA smart swith. I have 7 KASA switches (HS200, HS210, HS220). I see the same problem with all of them. Form the KASA app, all devices are unreachable. Some swithes have blinking green light. Some have red blinking light. Please help. Thanks.

 

I did some research online, and have taken these actions below. But haven't been able to solve this problem. 

1. Change my wifi to different channel

2. Reset my router

3. Restart KASA switch

4. Reset the KASA swtch and setup as new device. But I can't connect them to my wifi network.

@Alex0604 

 

Maybe your router recevied a update and upgraded the WiFi to WPA3 Personal

If it did set it back to WPA2 Personal

Let us know how you make out
