After the switches had been behaving for a couple of months, I had 2 out of 3 fail to reconnect to the cloud after I rebooted the router today.  I could turn the lights/fan on and off.  I had to delete them from Kasa, add them back in.

  @nsrdave I've left negative feedback on Amazon (where I bought it).  I don't think TP-Link sees this as an issue or cares.  They would have addressed it by now.  But for sure, it's probably the end of me buying their products.

Hi @Riley_S , have the engineers able to determine the cause of the issue?

All TP-Link devices are connected to the internet, all other home equipment are connected to internet, the only device that is not connected is KS240 fan / light switch with solid light which the troubleshooting guide says no internet but that is not true.

  @Aravot same exact issue here

  @Riley_S 

I have the same issue.  I have to KS240's installed and both have had the same issue.  I have a TP-Link Deco mesh system and the furthers router is only about 15 feet away...very strong signal.

I tried a reset and that did not fix the issue.  I had to reinstall via the app to fix. 

  @Aravot Same issue here on 2 of them.  Any updates?

 I just ran into this issue on a new KS240 that's only been installed for a week. 

@Riley_S, strange no comment from TP-Link, it is evident many users are having the issue, how about a firmware update to fix the issue?

 I am also experiencing this issue. I have tons of other Kasa devices on network that work flawlessly, but this one keeps going red and I have to fully reset it and re add it. Only for it to go red again a week or so later. Very annoying having to reconfigure all my scenes and automations every time. We need a fix, or I'll be ditching this thing soon. 

I have this same issue and reset at the breaker does not work. I also temporarily disabled automated firmware updates thinking that process might be causing issues, but that didn't work either.
