I need to have wifi near my outside gate in order to control it with wifi. My mesh system is working indoor so there is no connection at the gate. I have an old TL-WA854RE (EU) v1 that i tryed to use in order to extend wifi to where i need.

I have tryed everything and just cant connect to the any of the deco's.

Then i have created a guest 2.4ghz network without password and it worked, but i cant have a network without a password.

Any suggestion?

Also, there is any range extender that suports the internet security protocol of the decoP9/ Deco X20?
