Hi I have Cisco Switch SG100D-08 and for some reason when I plug the Ethernet Cable to PC the interface shows Identyfing network and ends up in Unidentified network. I tried setting an static IP and didn't work and changing Speed Duplex trying different options from Auto Negotiate to 10mbps, 100 and 1gb. The switch is working well because I test it with my laptop and worked fine. I think the problem comes from the PC motherboard, but I'm not sure, also tried reinstalling Ethernet drivers but didn't work. Any ideas will help.
