So the wifi module also bring BSOD on wii instead the bluetooth module
What i am curious that Many of the USB Loader User experience this problem(Disc loader is rare even none)
Yes a bad WiFi module will cause a BSOD. Have a look at the chart above. Its not as simple as a USB Loader issue as the OPs Wii not boot up at all and unless he failed to tell us the entire story, it most likely a hardware failure.
I included every thing i can think of just before it bricked on me.. So i am hoping it is a wifi module. And just so i know what can cause the module to go bad? The wii isnt to old got it last christmas.
