last time i tried the newest Intel Gigabit Ethernet Drivet from Asus.com and Intel for the onboard Intel(R) 82579V Gigabit Network Connection on my Asus Maximus IV Gene-Z/Gen3 it changed name in Windows 7 to Intel(R) 82579LM Gigabit Network Connection and i couldn't get any ip or anything, what can this be?

but when i use the Driver DVD that came with the board, i got no trouble with ip and that and net works, but what's going wrong with the newer driver?
