I am unable to login to Warmane WoW at all. I am on Icecrown server (So WoTLK) Client and I get an INSTANT unable to connect etc message yet all my friends are online. I have changed nothing. The message I get is
Sounds like Firewall. Either the access point is blocking the ports used by WoW (quite common in campuses and cafe's etc), or your OS is blocking internet access to the application. The first scenario can be tested by trying to connect from another location, for the second try a guide on how to add an app to the firewall whitelist, plenty of those on google.
