Control Panel, System, Hardware, Device Manager, Network Adapters, Click on Ethernet Wired Network Controller (usually shown by brandname), Advanced, examine the settings.
I'm not at that computer now, but I did check those settings. It is set on "Auto" and shows green light at 10mbps. I tried to set it to Duplex 100mbps and the connection failed and wouldn't reset. When I went back to the original settings the connection came back to 10mbps.
In network connections, when I disable and re-enable the connection it connects immediately at 1gbps, then I get the 'cable disconnected' pop up. It takes about 20 seconds to then reconnect at 10mbps.
I have the most up to date driver and there are no noted faults in the switch.
I appreciate your time on this!
