Determining which ports are open by performing port scans
Your best bet would be to install a network card. If that works, just disable the onboard network port in device manager.
You seem to be referring to a NIC (Network interface card).
"Port is disabled" typically means that a specific communication port on a device, such as a router or switch, has been turned off or deactivated. This can prevent data from being transmitted or received through that port, often for security or configuration reasons. Disabling a port can help protect a network from unauthorized access or reduce potential vulnerabilities. To enable the port, one would typically need to access the device’s configuration settings.
To connect a Cat 5 cable to your network device, simply plug one end of the cable into the Ethernet port on your device and the other end into an available Ethernet port on your router or switch. Make sure the connections are secure and you should be able to establish a wired network connection.
A network port serves as a communication endpoint for networked devices, allowing them to send and receive data over a network. Each port is identified by a unique number and is associated with specific protocols, enabling different types of network services to operate simultaneously on a single device. Ports facilitate the organization of network traffic, ensuring that data packets reach the correct application or service on a device.
If you connecting a hub to another device then the cable must be placed in the uplink port, or a port that can switch between a client port and an uplink port.
Wireless USB network adapters provide WiFi capability to any computing device possessing a standard USB port.
HUB in a collision Domain, Switch in Local Network.Broadcasting in network is done to locate devices in Network. Hub broadcasts through all its port whereas Network Switch Broadcast traffics within a Port & out of all ports only if new device is to be found.
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.
