Details:
Windows 7 64 bit
Gigabyte GA-Z77x-up5 th motherboard (F4 bios)
Recently installed 7260 ac HMWG wireless card. 17.1 driver Working fine. 15 MBS
Problem: The network interface (wired) was only running about 20MBS and the 82579V adapter Advanced properties tab was blank, so
I decided to uninstall the driver and do a reinstall. First the 19.5 driver, then the 17.2 from Gigabyte, then the 11.13 driver from the
install CD from Gigabyte. All report back: "Cannot install drivers. No Intel adapters are present in this computer."
