After lunch, the Personnel Director said that his computer did not have a net, and colleagues have been repaired for a long time. The most tired and most tired living person of this dry. It took a long time to confirm that the network port, the network cable, or the network card, or which part of the computer interface is broken. Finally confirmed that it is a computer problem, but the NIC shows the work. It's really nothing.
Later, I updated the driver of Realtek RTL8139 Family PCI Fast Ethernet NIC, and then I would get online. The problem is solved, it seems that some problems are really ghost. What should I solve when I don't know.
