I am from the US and I'm currently studying in Spain and on the roof of my house here, I have a very strong connection to a wireless network that is titled, "wireless". It is not locked and doesn't not require any kind of password and I connect right away without it saying that I have limited or no connectivity. When I try to open a webpage or get on the internet in any way, however, it just won't work. I don't understand why it says I have a strong connection, but won't actually connect me to the internet. Can anyone help me? Thanks!
