My CFS3 problem

I bought this game so I could go online and play multiplayer. I had to buy a joystick and then I had to get a decent ADSL connection, because a 56k modem was too slow.
Since getting ADSL I have had an intermittent problem connecting to the multiplayer server, which results in me only being able to connect about once a week (if I'm lucky). I don't have any other internet connectivity problems.
I've already checked my router, my firewall, etc, and found nothing wrong. (there is no error message, the list of games just doesn't appear)
I have posted my problem in this forum (early April) but no one seems to have a solution or any suggestions as to how I should troubleshoot the issue.
Does anyone have any suggestions as to what I should do from this point?
