Anyone can help me to pass through my problem? i can't get the Lan working in asus P5GC-MX / 1333 . can you sent to me Driver Lan Ok ?

I'm Using:
Asus P5GC MX / 1333
E2180 Dual Core 1.8GHz
DDR2 1GB Kingston
X1650XT 256MB DDR3
Harddisk 160GB Seagate
500W PSU
Leopard 10.5.2

I have the same MB. It use Atheros L2 chip which not working for now. I use Realtek 8139 which working out of the box. It cost ~5$.

I can't for the life of me with that mobo get my realtek 8139 detected, it only allows me to use serial ports, I've installed everything correctly and people say it works oob, but I'm having issues.
