Ethernet conroller troubles, please help!!

Hi all, My problem is that my hard drive recently broke completely so I had it replaced. Since I have had the new hard drive however my ethernet controller has not been installed properly and I cannot share my internet connection. I suspect the drivers were left on my old hard drive but not on the recovery CD. How can I find on the brand and model of my ethernet controller and the model number so I can download the correct drivers for it. Does anyone know which ethernet controller is used in an ADVENT 3216?
Thanks

Look in the Device Manager: Start/Run/ devmgmt.msc

Click the + next to Network Adapters.
