Note that if your ISP or networking environment prevents using custom DNS servers, str2hax will not work and you should choose another exploit to use.

str2hax is an exploit for the Wii that is triggered by loading the Wii’s End User License Agreement. It requires nothing but an Internet connection that lets you change the DNS on your Wii.

If you have installed a mod like CTGP Revolution or Project+, str2hax may load that instead. If it does, restart your Wii and try again without your SD card inserted.
