LAN missing after using bridge.

I set up a bridge connection between wireless and LAN.
It work fine at that moment but on the 2nd day, my LAN is not inside the Network Connection window anymore.
I also could not find my Ethernet at device manager. However the wireless network is still working.
I am using laptop and my driver is Atheros.
How do i restore back my LAN??
