I have my Wap AC now connected to a D-Link DSG1210 POE switch. The switch has GB ports and to other devices it links at 1000Mb. The Wap AC also has a 1000Mb Ethernet port or not. Then why does it only link at 100 Mb? The switch is set to auto negotiate. Can the Wap AC be forced to link at 1000 MB?
replying myself. it was a bad Ethernet cable!
