I can't join ANY Minecraft servers? - 1

When ever I join a server it will load the little area I'm in, I can't do anything but walk around in this area and none of the mobs move around. After a while it will either come up with timed out or with the disconnected by remote host error message. This is on ANY servers, including the realms servers which means it has nothing to do with server addons. I've looked at my Firewalls and tried adding rules to them to allow Minecraft to connect and that hasn't made a difference either. Really need help with this, been a problem for a long time now.
