The issue has been ongoing since the game was release on September 25, 2012 in North America. Certain modes such as FUT (Fifa Ultimate Team) are not even useable at times. The problem is during a match, for no apparent reason many users are experiencing a connection loss to the EA Sports servers. This is not enjoyable at all and quite frustrating. Many threads have been made on the EA Sports FIFA 13 forum, but it seems that there haven't been any results. Examples of a thread below. I would like that this problem be solved so that I can enjoy the game that I paid for.
