Network, so confused now lolz~?

have your parents blocked your access to facebook, possibly? try installing different browser ex. firefox, google chrome... that's if they blocked it in browser, if not in browser, then check your firewall status, or your internet security suite status, check for any parental control software that they might hav e installed without your knowledge... also installing flash or shockwave player might solve the issue? not really sure what else could be wrong since your internet connection is working.... good luck!

You have been blocked by your network manager. If you are at school then those sites will be banned.
