I'm not sure if I'm in the right thread. I've had the Kasa system for about a year and working fine. I just recently installed the Deco XE75 and a TP-Link 5-port Managed Switch to my system. I turned off the WiFi to my AT&T router and set the Deco system to AP mode. I kept the same SSID/Pass of the original system so I didn't have to re-pair all the switches. The system worked fine for about a day. Then I started noticing some of the switches going offline. Some would go offline then back online. The Kasa Panning Camera is off line as well as the one Kasa smart outlet (KP200). I've restarted the Deco system, turned off fast roaming, and then beamforming to no avail. I've seen the online clients numbers in the Deco app go up and down and the smart devices in the same app go offline and online like in the Kasa app. I've also noticed them going offline on the Alexa app.

As I said, the switches/camera/outlet worked fine before I got the Deco system so I think it has to do with the new equipment setup. I really want this setup to work because I've been very happy with the TP-Link products. Please help.
