If you named your new router the same network name and wireless password, try and turn off your smart devices, be it unplugging it and plugging back in or switching the light switch off then back on. See if the devices reconnect, and if they do not, factory reset the smart device and then set up the device. For example, for the smart plug, hold the side button for 15 seconds or for the smart bulbs, turn off the power off then back on five times.

I had to replace my CenturyLink modem/router. Since then, no Kasa devices respond. When I click on any single device (on my iPhone via Kasa app), I'm told Device Unreachable. 

 

I can't ADD, CHANGE, EDIT or DELETE any device and I don't see the TP-LINK listed in my Settings/Wi-Fi.

 

How does one resolve this?
