The wireless hardware on the Wii is a [https://web.archive.org/web/20120609045225/http://www.wiire.org/Wii/console/wifi_card BCM4318-based daughterboard] that connects to the Hollywood via an internal SDIO bus. Information on this device is scarce.

See http://www.gc-linux.org/wiki/Wii:WLAN for additional information.

IOS's WL driver contains a lot of code that matches up with the code in the [https://android.googlesource.com/platform/hardware/broadcom/wlan/+/refs/heads/eclair-release/ Android broadcom.git] repo, specifically [https://android.googlesource.com/platform/hardware/broadcom/wlan/+/refs/heads/eclair-release/bcm4329/src/bcmsdio/sys/bcmsdh.c bcmsdh.c] and [https://android.googlesource.com/platform/hardware/broadcom/wlan/+/refs/heads/eclair-release/bcm4329/src/bcmsdio/sys/bcmsdstd.c bcmsdstd.c]. That driver, combined with the knowledge that the BCM4318 is connected to the Hollywood via a standard SDHC at 0x0d080000, is probably enough to get WiFi working.
