Out of power in both bathrooms
	
	
		We just bought a 26 yrs old house. I was testing all switches and outlets. All worked fine except one outlet in the living room.
It seems to me that ONE switch in the master bedroom closet controls nothing (or an attic outlet?). I turned it on then both bathroom in the same floor are out of power. The closet(next to one bathroom) is out of power too.  The master bedroom still has power.
All breakers are on in the Main Electrical Panel. I couldn't found any Subpanel or GFIC outlet in the whole house. 
For the living outlet didn't work in the first time, I took it out and found no wire has power.
Thanks for your input.
