Connecting new Wi-Fi extrnder

Hi, It is my first post on this website so forgive me if I don't know much but I can't comprehend the versioning being offered through automatic updates in Tplink interface. I got wifi 7 extender RE40

I have multiple tp-link wifi extenders at home. This RE705X is the best of them. I have upgraded my 5G router recently (tp-link) and I had to reset all the extenders to use the new wifi. Each extender

Reinicie mi extensor y ahora quiero vincularlo nuevamente pongo los datos y me dice ID o contraseña incorrecta pero lo corrobore 9 veces y sigo sin vincularlo

Conectare prin login on router
