@lolo32 then you probably have a defective device, then you need to contact tp-link support Mybee @Hank21 or @Clive_A from tp-link can help you.

@lolo32 this is a good description how to recover https://www.tp-link.com/en/support/faq/3062/

@TroyT if you have EAP225-Outdoor you can try this from Ubiquiti. Ubiquiti UMA-D

@flips01 when I installed I chose 2.4 or older compatibility, this was a choice I got during the installation. don't remember all the details in the screenshots
