i am able to connect to my wifi at home. but, when im trying to connect to the wifi in my school it is saying wifi do not have a valid configuration. please help me.
I'm sorry nithin27, but your post is too general to give an accurate answer. I will try to help you though .
Since you can connect at home I'd say there is nothing wrong with drivers etc. It is either working or not, there is nothing between it.
So, the fact that you can't connect at school tells me that you need some sort of autorisation to connect. Like a password/ passkey etc.
You might want to take a look at the configuration of a classmate and see what is different. A visit to logistical support at your school may be helpful to.
