Hello,
I am trying to use a realtek NIC under Linux (Debian 7.1). It is the onboard ethernet in my Gigabyte 990FXA-UD3.
I've downloaded and started to use the r8168 driver, as opposed to the free r8169, however both drivers result in the ethernet not negotiating to gigabit speed or pulling an IP address via DHCP.
Since almost everybody having this issue with this NIC seems to have their problem solved by switching to the r8168 driver, any troubleshooting beyond that step would be much appreciated.
Unfortunately my switch and my router are gigabit, so slower network hardware isn't an option for me.
useful console output follows:
