No Internet Access But Browsing Works Fine?

So,I'm living in a university campus and I've got an internet connection via a proxy server.The thing is,when ever I plug in the network cable,my PC recognizes the network,but the little network tray says "No internet access". But the curious thing is that the internet actualy works.My browser works,I can access any website (well,except the restricted ones via proxy) but it works just like any other internet connection in the campus. But,recently I've got my hands on a VPN account to have access to things that my proxy wouldn't allow me (torrents for example).But,probably because of that "No internet access" problem,when ever I try to make that VPN account,it tells me that I need to connect to the internet first. I already am,but my PC still keeps requiring an internet connection.I can't manualy connect to it,since I don't have the ISP data required. I've only got my VPN account data (VPN username and password).

This is kind of annoying,since this only happens to me,my other room mates don't have this problem,they plug in their cables,their network adapters recognize both the network and the internet access. Only mine says "No internet access" but the internet works fine.My operating system is genuine,when ever I go home and connect to my home network this problem doesn't ocure anymore,this only happens when I connect to my university's internet connection.I've tried reinstalling my operating system.Still no results.I'll attach a printscreen so you could see exactly what I mean.
