Help with controller (netplay)

[GrizzyBeer]

So my friend just got netplay and he's picked up the may flash adaptor and for controller hhe got the new smash bros black one. Now the problem is hhis c stick doesn't really work most of the time BUT on the controller setup screen it shows it works fine. He has the optimal settings in place ( ie radius 100) so if anyone has encountered a similar problem and knows what to do help would be much appreciated
