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:
