I have installed Windows 8 consumer Preview in my computer and I am facing a problem as my Ethernet Controller is not working. Before Windows 8 I had installed windows 7 and that time I had installed Realtek Ethernet controller (RTL8139/810x Family Fast Ethernet NIC). That time is was working fine but now after I have installed windows 8 and I tried reinstalling Ethernet Controller it does not work shows up an error code 10 (device cannot start). I've tried running the setup in compatibility mode for Windows 7 but it doesn’t work. I also tried to dis-able and en-able the Ethernet adapter but still nothing worked. I even tried to install other Ethernet drivers but no use. I also tried to install the drivers in safe mode with networking but no use. So guys someone please help me out what should I do.
