cant play on-line games in softmod wii -W H Y????

Hi,
I have a softmod wii 4.2 U
installed Priiloader with different hacks
use wiflow to run games from HDD
all work fine even upload covers from the internet (wireless)
but it when i try to play online games such as black ops, medal of honor etc the wii tells me that it cant connect to the server
any idea how to solve it?:confused:

try deleting your network settings and then set them back up again.
I play black ops online all the time, only difference is that I use CFG USB Loader.
