Well I ve tried that app, but since there are no servers nearby the ping reaches 500-1300ms I don't think is that but I fear that the application changed some settings etc ( I am not expert on this kind of staff )..
I got a rooter-and connect by wi-fi, however I also tried to connect by cable; still the same.
_SaV_ explained some things to me and helped me to assign the game to my router manually.. I added the ports, but that didn't changed anything either..
What worries me is that I can connect to a small number of people..
I ve already tried turning off my firewall and AVG..
