Arch Linux pacman error: failed retrieving file

I just installed Arch Linux today. I am trying to install elinks using pacman -S elinks And I get a long, long list of: error: failed retrieving file 'elinks-0.13-17-i686.pkg.tar.xz' from some.mirror : Could not resolve host: some.mirror The same happens if I try to install any other software. The only thing I could think of based on what I read is a connection problem, but I'm on the same connection that I used to install the OS, and that was just a few minutes ago.
