Hi again!
But I've been able to test it finally... I had a switch, a cable from the switch to my pc, and another to a wifi modem. Now i got rid of the switch, my pc goes into the wifi modem's cable port, and the ipad now can receive the broadcast when sent from my pc

thanks!
Only problem is that sometimes(very few, actually) it still fails, and the AppGameKit player seems to get stuck at the "Tried to flush data on an unconnected socket" for some time untill I can try again. But it's ok, at least now it works!
