Currently NOT at home, will add more information later on.
[Router Model]: ?
[Problem]: Whenever I'm connected directly through wifi to my router, I can't access any Game Servers (Steam, League of Legends, World of Warcraft, ...) but I can surf on the net. I tried forwarding ports, didn't change a thing. I tried changing the IP, same. I enabled UdnP, in case of, didn't do a thing. However, if I set my iPhone 4S on the wifi and then I share my iPhone's connection (which is the wifi of my router) to my laptop I CAN access to game servers (with a huge ping of course).
Thanks in advance
