I'm having the problem as well. I've only just bought the game and last night managed 300 or so megs at 8 k/s. Now I can't connect at all. The tech support has just given me automated emails and all the while my free month is dwindling away. And this is after all the problems of creating the account in the first place.
As someone new to ncsoft's products and CoH, I am not impressed. I have never had these kinds of issues before with an MMO, and certainly didn't expect them in such an established game. I'm almost at the stage where I just want my money back, as I've wasted hours of my time digging through forums, opening ports, changing tcp/ip settings etc
It's just not good enough
