The stock NIC on my MSI Big Bang Xpower is a Realtek PCIe GBE RTL8111DL adapter. The NIC is reporting a speed of 100.0 Mbps, but the manufacturer's website says it is a Gigabit controller.
I read the NIC will auto negotiate the connection speed to the highest availalbe. I have it connected to a D-Link 5 port DGS 2205, which is a Gigabit device. Since both devices are Gigabit, I would expect the NIC to connect using a Gigabit speed.
I have another computer connected to this switch, and that comptuer is reporting 1.0 Gbps. So I suspect a configuration problem with the first computer's NIC. All connections use Cat5e cable.
How can I configure this Gigabit NIC to connect at speeds of 1.0 Gbps?
