Hi @shail1947 . Have you tried a different power point. If using a power board, different outlet on board. Or extension cord temporarily if no other power point close by.
I doubt that NBN can send commands to router to turn it off. If it happens so often, remove data cables from Tplink and leave it switched on and see what happens.
Does the unit feel hot? It does get warm but no so hot you can't touch it.
Is it near anything that gets hot?
What do you do to get the unit back on?
