Answer:
The gateway's i.p address is incorrectly configured on the workstation.
Step-by-step explanation:
The gateway provides an access point for the workstation to send requests for information to the internet. In this scenario when the workstation requests a web page from the internet the request is sent via the gateway, then to the internet. However if the gateway is incorrectly configured it means the workstation will be unable to send any requests through to the internet.
