Myi iPad unable to join my home network but it can join other network but other devices can join

My iPad 3 cannot join only my home network. But other devices can join my home network ( such as notebook Mac air iPhone and other iPad 3). But it can join other network such as hotspot from my iPhone. Please suggests me how to solve this problem

Could be several reasons... the home wifi hotspot could be limited to the number of devices that can connect... you''d have to have the ability to allow more devices to connect at the same time.
