Atheros AR8162 not detected in Fedora 17

Could someone please shed some light on this issue?
I recently bought a Toshiba laptop (S855D) with this network controller inside.

Atheros AR8162/8166/8168 PCI-E Fast Ethernet controller (NDIS 6.20) card.

The system did not detect the card, when I checked network manager only the wireless (Realtek) card was showing.

Any suggestion would be greatly appreciated.

Thanks
