Windows 7: Wifi Adapter cant obtain ipv4 and ipv6

Wifi Adapter cant obtain ipv4 and ipv6

I use college wifi connection.
I am having this issue from the past two days.
I cant connect to the internet through wifi(LAN works)!!
I can connect to the wifi network. But the network name contains some number at the end in my connections.
(eg:- if the SSID is "router", my laptop shows it as "router 2", "router 3" etc or unidentified network..)
And i cant connect to the internet!!

When I see the details of the connection, i find that the ipv4 and ipv6 related items are blank.(screenshot attached).

All my friends can have internet access(so not a router problem).
Also, the same problem occurs in windows 8!! (dual boot laptop)
Ive tried troubleshooting, uninstalling and installing the drivers, updating drivers etc and none of them seem to work.
Ive also tried "netsh winsock reset catalog" and "netsh int ipv4 reset" commands with no luck.

What exactly is the problem??
Is it a driver/software issue or a hardware issue??

Here is the ipconfig result.
Please help guys!!!!
