I recently changed the OS of My Acer Aspire One D255E Notebook from Win7 Starter to Win 7 Ultimate 32 bit. Ever since I can't connect my pc to the internet via cable and the from the driver manager, it shows that Ethernet Controller is missing. I have tried to download the network drivers from the manufacturers website with no success and I read somewhere that updating/ flashing the BIOS may help with the problem. Now I was wondering if is there any thing else I can do before I resort to that last option which comes with so many risk. I'd also appreciate if someone can tell me the easiest way of doing so!
