I have one unit connected by cable to the main unit because it is far away, but it ignores it as it is still within the range of weak wifi coverage, but why does the deco ignore the wired connection when it works great via cable, why can't I set it as the preferred connection via cable in that unit !!! !!
Sometimes it connects to the cable and after a while it switches back to the wifi connection and the signal is already bad but via the cable is excellent, it would be necessary to add this option to the settings so that it prefers the cable connection when the unit already has a weak signal coverage
