So I just purchased a USB to ethernet adaptor (Model KY-LANRD9700) for my MBA 2011, running mountain lion. I opened up the package and it had a driver installation CD. Now since the MBA doesn't have a cd drive, I used remote disc with my other windows laptop. There was a folder named setup, but the only thing in that folder was a .exe extension, and i'm not runnin any windows on my MBA. THe other files were in a fold called USB.LAN,RD9700 Driver.... and I installed the drivers that were in the Mac folder. After restarting my computer like it said, i connected it up to the modem and my MBA, and turned off wi-fi, and nothing was working. Did i Do anything wrong? Do i need to get the drivers elsewhere? Do I somehow have to enable a LAN on my MBA? HELP!
