Yah exactly what RAMChYLD said. Are you sure it is RED the power button.
Cos my wii was set to this settings since i guessed few months ago.
I dont feel any heat to it in standby mode.
And also i dont get any updates from nintendo if my wii is on standby mode as well.
Only will get the updates when i Power On my wii ( thats when WC24 is on automactically )
As for last time before i had GH5 , normally i will just turn on WC24 from the settings if i need to use this function.
After i started playing GH5 or etc, thats when i use this function by turning the WC24 standby mode OFF.
Cos for convienient sake , i dont need to go to settings on and off each time that is becos GH5 online uses WC24.
Hmmm.. i wonder urs is different?

Yes, it is. I'm not that blind hahaha.
I do mean serious business. I got mail even when WC24 has "
" off.
