I had to do a clean install of Windows 7 (Home Premium, x64) on a friend's y470. I was able to find all of the drivers that I needed besides the networking driver for the Broadcom NetLink Ethernet. I've also had no luck finding the correct drivers for my y570 with the same ethernet adapter as well. All I'm able to find are the drivers for Windows XP, and I've tried those, but with no success. Does anyone have any ideas, know where I might find them, or has had the same issue?
