It’s not exactly a distro for a PC, but it’s still useful. The DD-WRT Linux distro, is designed to run on a lot of different Wifi routers. Specifically the Linksys WRT series. A buddy of mine helped me set one up. The router, as it comes from Linksys, is pretty stripped down. But, once you put DD-WRT on it, you can do a LOT with it. People have set them up as lean-servers, or as streaming media clients in a home-theater configuration. Mine, has been configured to work as an ethernet bridge between my TiVo box, and the rest of the wireless network. Rather than buying a wifi adapter. Nice solution I thought, and it extends my wifi range.
