Network doesn't have a valid IP configuration

Have you tried power cycling the modem/router combo plus all TP-Link devices.
First with everything unplugged for at least 30 seconds, start by powering up the modem/router first giving it a few minutes to boot up, then plugging in the TP-Link devices.


What is the model of the TP-Link? TP-PA210 or 211


Can you post the ipconfig /all in this thread.
