First off, you'll need to find out exactly what chipset you've got hold of. In my experiance
, the revision didn't bear much relationship to the chip. If you've got a different chipset to mine things might be tricky, but I'll see what I can do...
Install the default drivers that came with the card, or whichever ones it accepts.
Right click "My Computer" on your desktop, and select "Properties" from the context menu. Select the "Hardware" tab on the window that appears, then press the "Device Manager" button.
Those steps are for a computer running XP or 2000... If you can't find the Device Manager on your system, lemme know what OS you're using.
Anyway, once the thing's up, double click "Network adaptors", then double click your wireless NIC off the list. On the new window, select the "Driver" tab, then press the "Driver Details..." button. You'll see a list of one or more files. Post that list here.
Edit: I might just note that I originally purchased this card because the revision was supposed to use a certain chipset that can be used to re-flash the firmware in the DS. I wasn't terribly impressed to find out that the card I ended up with wasn't of the right type. It wasn't until some time later that I had the idea of using it as a WAP to get on to the WiFi network. Once I got it to work, I got myself soundly thrashed by some japanese gamers, called the experiment a success, disabled the card and haven't touched it since.
