Hello, recently (since around May 18, 2012) I have been having connection issues with my Xbox Live. Each time I join a match of, for example, Modern Warfare 3, I will get around an average gaming ping, 3-4 bars. About halfway through the game, I begin to have complications where my ping will rapidly change from really low, to really high in a matter of seconds. The connection status bar begins to jump from 4 bars to 2 bars to 1 bar, eventually making me have around a 3 second response delay. I have tried everything from opening ports on my router, to trying to wire my connection. I was wondering if anyone can help me with this issue, because it's making me just want to stay away from it. The other odd thing is that I seem to have no trouble on a PC with the connection, but on the Xbox it just shuts down. Additionally, when I restart my modem the issue seems to disappear but then comes back within about 10-20 minutes. My modem is Cisco DPC3000 and my router is D-Link DIR-815, and if it's any consolation, my ISP is Cogeco (Canada).
