Really. I have the same model. It barely covers a small house like mine which is 1000sq ft with the 5Ghz signal. What size is your 4BHK and do you get the 5Ghz signal everywhere in the house?I've a Archer C80 and works perfectly for 4BHK on one floor.
For multi storey you'll need more than just one router!
