See also: https://web.archive.org/web/20180817063137/http://www.gc-linux.org/wiki/Wii:WLAN GC-Linux wiki page about the Wii's Wi-Fi card, goes into great detail about the hardware and explains why it's so slow

The Wii and Wii U features a Wi-Fi chipset from Broadcom, specifically the Broadcom 4318.

This Wi-Fi adapter is unfortunately heavily constrained due to it's connection, it's connected over Sonics Silicon Backplace (SSB), connected over SDIO on SDHCI1, on the Hollywood and Latte SoC. The overhead of interfacing with this Wi-Fi card along with various standard network protocols are very taxing for the Wii's CPU.

Compatibility

Wii-Linux has included support for the Wi-Fi chipset since at least MIKEp5[check]. Upstream Linux also has drivers for all components of the Wi-Fi stack available, although they don't seem to function on the Wii. It's unsure if this is known about by the upstream maintainers, but it seems to have been broken since at least Linux 5.0.

NetBSD also includes support for this card.
