@Tony last question, from where are the speed tests? if im at the deco 3, does it takes the speedest from the main deco? or how? with my pc and speedtest i get way lower via lan connection

@Tony it actually fixed it, so a firmware issue! ty for your help :)

@Tony okay, did it what now

btw does powerline etc srill works if in Ap mode?

AP Mode, deco1 is connected via ethernet plug to the switch/router. it lights green. Deco 2 and 3 (slaves) wirh wifi, even if i place them near the deco1, they are green after the reset and adding to...

@Tony i didnt try that but my router doesnt have wifi, could this be the reason? its green for a short time and then instantly gets red blinking, i resetted it already etc
