I have DP55WB motherboard with 82578DC Gigabit network connection. The wired network is not working at the start of the machine. I have to disable and enable every time for the network to work. I have Windows 7 Ultimate. This problem started couple of weeks back after I had to reformat my hard disk to resolve some issue. Prior to that the network was working perfect. No New software was installed. How can I resolve this issue?
The network card may need the drivers again. Try to get the latest drivers from the following link:
On the Device Manager you can confirm what drivers are required (yellow marks)
