I was looking around at WiiFi dongles (and actually bought one that claimed Mac compatibility, although when I got home the drivers were listed as only compatible up to OS X 10.6, and I was not able to get it to work). Why do I want one? Well, I want to use Internet sharing to share a Wi-Fi connection, but you can't do that normally because the Mac needs to share the Internet on a different interface than it is receiving it. This would be useful for me when I am in places with metered Internet that charge per device (such as certain hotels in countries where the Internet is heavily metered/expensive), so that I can have only one device connected, but get the Internet on multiple devices. Since all Macs have built-in Wi-Fi, this appears to be a market suppliers have abandoned. Does anyone know of an OS X-compatible Wi-Fi USB dongle?
