Finally I've found the time and courage to strip the network cable in the wall and attach a new plug to it. On Sunday I did a dry run on an extra cable I had around and messed up the wires color order. Apparently reading is very hard since I did the same thing today 😅 . But later I managed to figure it out. I'm happy, because now my wireless access point could be placed in the wall, and powered by PoE.
