What should you check first if a workstation cannot access the internet while other devices can?

When troubleshooting a workstation that cannot access the internet while other devices can, it's crucial to consider multiple factors that can affect network connectivity. Checking the workstation’s subnet mask is important because if it is incorrectly configured, it could prevent the device from communicating with other devices on the network. This can lead to issues connecting to the internet.

Next, examining the network cable connection is a fundamental step. A loose or damaged cable can cause intermittent or complete loss of connectivity, so ensuring that the cable is securely plugged in and undamaged is vital.

Lastly, reviewing the workstation's DHCP settings is necessary because if a device is set to a static IP that conflicts with another device, or if it is not correctly configured to obtain an IP address from the DHCP server, it may fail to connect to the internet.

By evaluating all of these aspects, you can effectively determine where the issue lies and take corrective action, making this comprehensive approach essential for proper network troubleshooting.
