@TP-Link there wasn't any firmware upgrade, yes that's the same link I used for the firmware recovery and it showed it was successful, and still the same issue persists.

@RM001 I had also tried resetting and changing power cords but it still doesn't seem to work

one of the units of the mesh system is stuck on yellow light for some reason, i had even tried the firmware recovery fix but it just doesn't seem to work. any solutions? I had purchssed the 3 pack...
