After a lot of searches on the net, I found 2 ways of using the fake RealTek (Hangzhou Silan) ethernet card on Ubuntu
1. Using NDISWrapper –
This is a wrapper which allows the Win XP drivers provided for the above card to work on Linux
2. Someone has written a driver for Linux and you can download it from here. The tar has a readMe file which has detailed instructions on how to configure it.
I tried both options and the network card is detected now but I when I try to set the IP, my system hangs. More updates later..
I tried a lot to configure the ethernet card using the above options but failed to get it all done. Maybe my fake card is a third rate thing. Anyways, there is a hope that the next release of linux will have support for this card. But until then its back to Windows for me 😦
