82579v gigabit ethernet controller

[idata]

Hello

im posting here out of complete frustration as this ethernet card refuses to work correctly.

I have an asus sabertooth z77 board

connection is wired via BT Homehub 3.0

Upon cold startup no connection is detected and i get an error stating "hardware or driver issue"

Now i have read a few threads and have tried updating/downgrading BIOS

Fresh install of NIC drivers

Install NVRAM utility

and updating intel ME

also checking power managment settings on the controller.

Nothing works!!

I have to disable/enable the device in device manager for it to work again.

From a restart there are no issues

any advice is great as at the minute im sick and tired of trying

I have exactly the same problem on the asus p8z77-pro v board...

tried all recent intel drivers, flash update, bios updates.. no go.

looked everywhere. finally ordered a pci-e nic which is ridiculous but im so sick of have to disable and enable the device on every cold boot. Still want it fixed though, was not a cheap motherboard and went with it because it had an intel chipset!!
