problem with internet connection

hello, I lose my internet connection playing POE, this only happens when I play POE and I spend several times since the game was released, I just died recently back 49 marauder, what happened was I was running short and suddenly I could continue to walk but can not talk or attack when I reboot BOOM! default

anyone know what could be?
