wifi/ no internet connection/ proxy/ netflix

[boalles]

Have bought a macbook pro in Gibraltar and now having problems with the internet connection when I am in Spain and also in Gib. I can only access internet when I use IP vanish. But when I use Ip vanish and want to use netflix, it says that I am using an unblocker or proxy.. I think I need to change something with the proxy. I looked under settings, tried different things, but still does not work.
I want to use internet without IP vanish.. just with the wifi when I am in Gib or in Spain...
Can anyone help me out here?
Thanks
