I have an xbox 360 slim and im using a wireless connection. I can watch movies on netflix and search the web fine but if I play online games i get disconnected within 10-15 minutes. I have tried opening the ports needed for xbox Live on my router settings but when i do so it shuts of all my internet even to my PC and the wi-fi, but it all turns back on when i close the ports again. There is 8 different devices connected to the wifi and i thought that might be it so when no one was home i made sure the only thing using the wifi was the xbox, but i still got disconnected. Please help me, ive tried everything.
