Here is the original Network driver.
You'll have to download it on another computer, save the file (sp44579.exe) to a flash drive and put that flash drive into the p6330f and double-click on the file. Allow it to install and then try the Ethernet connection again.
Original Realtek Networking Controller Driver version 7.6.820.2009 (sp44579.exe)
