To test an Ethernet port, you can use a known working Ethernet cable and connect it between the port on your device and a functioning network device, such as a router or switch. Check for a solid green or orange light on the Ethernet port, which indicates a successful connection. You can also use network testing tools or software to further diagnose the port's functionality.
To test an Ethernet port, you can use a known working Ethernet cable and connect it to a device with a functioning Ethernet port. Check if the device recognizes the connection and can access the network. You can also use a network testing tool to check for connectivity and data transfer speeds.
