Lately, my Xbox has been acting strangely regarding connections with Xbox Live. When I test out all connection, all seems well; it informs me that I am connected to the wireless connection, internet, and Xbox Live. However, when playing a game or attempting to use features on Xbox Live regarding games informs me that I am not, in fact, connected. All attempts made to remedy the issue such as re-connecting and restarting have failed. If anyone can shed some light on the subject, I would be most grateful.
