is pretty up to date - I got wifi access for whiite and mike-p5 (though you need to boot from bootmii, ie. before the system menu starts)by paulcc - Wii Linux
I followed the instructions for Whiite on/reachable from and it worked for me. Make sure you do all of the steps.by paulcc - Wii Linux
It seems that you need to boot linux directly - eg. by selecting the boot loader via bootmii - this works for me. If you run linux via HBC, I think linux can't get control of the wifi deviceby paulcc - Wii Linux
