My pcie wifi card is an orphan! ('unclaimed')

[Bullwinkle]

I've tried to install an ASUS PCIe wifi card in my box (for connecting to my tablet). It's based on the Realtek 8812AE chip. Golden Ears sees the chip when I enter

sudo lshw -class network

but says it is "unclaimed" (unlike the wired ethernet chips). I take this to mean no driver has "attached" to the card.

I have tried to load a driver running the install.sh program on the ASUS cd included with the card, and also by editing source.list and then using apt-get to tap online versions of the driver, but get the same lack of cooperation I saw using the ASUS cd.

Any advice? Thanks for considering this.
