In my infinite wisdom I believed the Amazon listing page for this USB wifi adapter and that it supported Vista. It in fact does not which was confirmed by the lack of Vista compatible drivers on the ASUS page, and by the ASUS support rep I reached out to. This thing isn't even heavy enough to be a paperweight, so as a last ditch effort I'm checking here to see if anyone has managed to mod the drivers for one of these things before I go flushing more money down the toilet.
I believe there are some drivers out there that do support it on Vista, but you'll need Test Mode on. Unfortunately, I can't remember which ones they are. Best of luck.
Haven't come across them yet. Going through a second round of the tech support Olympics with asus lol. Thanks though! Worst comes to worst I'll buy a better solution. I've heard these usb things aren't that reliable anyways.
