Home assistant / TP-Link Kasa - updated

I’m new to this. I installed Home Assistant and was able to add about 20 TP-link Kasa smart switches and plugs. After a short while, all the devices were disconnected. Are there any known issues that I need to know about? What information should/can I provide here to get any insight and help?
I’m guessing that the DHCP issues new IPs to the switches and they’re not automatically rediscovered by Home Assistant. Is there anything I can add to re-discover?
Also noticed: I use LanScan to see devices on my network, and so it pings devices. When the home assistant is connected to my network, all devices go on and off, but when I disconnect the home assistant, they constantly respond to ping.
Thank you!
