Bad Internet

It shows that I'm connected and have good signal strength but neglects to send any of my MSN or Skype messages and will randomly disconnected me from either of those programs. That isn't so terrible considering I can just see who is online, incoming messages don't work either. It was working fine earlier today but go progressively worse. (As more people came back to the hostel to use it?) Either way it's really annoying and I doubt I'll have internet at my place until later next week.
