Why won't Ares connect on my other computers?

Hi, I'm having a typical problem with Ares but with a twist, I have 3 computers connected to a router the first computer that I connected to Ares went online in a matter of seconds, however the other 2 will not connect. All of the computers have access to the internet however Ares doesn't, its driving me insane. Firewall settings are properly set, I don't know what to do anymore.
