Iphone can't connect to Wi-Fi? - 1

My laptop connects just fine to the Wi-Fi network but anytime i try to connect my iphone, even with the right password, it just says unable to connect to Wi-Fi. I've tried with other telephones and i have the same problem. But somehow laptops have no problem connecting to the internet. How do I fix this? Is there a way to pass the internet from my computer to my iphone?

Have you tried other networks?
It could be a fault in the iphone which could have happened after dropping it
