The only thing I need to do is see if I can make this Tenda W311M USB Wifi Adapter to work... because right now, I am tethered to my iMac via ethernet cable and using Internet Sharing. Any ideas for that?
If it is Ralink based, I think Edimax bothered to produce/adapt PPC drivers. Theirs might work if you can identify the right chipset used in the Tenda. Otherwise, a PCIe carrier card with a 2006-era Apple Broadcom WiFi mini-PCIe card is the way to go.
