selecting wifi module

Can one please tell me choose the right wifi module to connect my arduino to internet ,
i bought esp8266 ,but i'm unable to find suitable requirements with that

Your post is incoherent but, since you already have an ESP8266, why not stick with it? It is universally popular, well-recognised as the best way to go, and well-supported on this forum.
