I have a server lab with an ASROCK motherboard. Built this server about 6 months ago.
Today, while working on it, the NIC Local Area Connection (Ethernet) suddenly showed that the cable is unplugged. After checking the cable and router, I went to device manager and the REALTEK device shows that it is working fine.
I've tested the cable, tried other working cables, nothing. I then went to REALTEK's website to download the updated driver and installed it. Still nothing.
I've never seen a malfunctioning NIC card that would only not recognize a cable is connected, yet will show up fine in Device Manager.
I happen to have an expansion PCIe Ethernet card that I will put in later this week, but I was wondering if any of you have run into this on a server setting before? I did not physically check the inside of the ethernet port yet, maybe one of the pins got loose or something for all I know.
Any suggestions our comments would be appreciated it. Thanks
