Diagnosis:
Checked the device, IP configuration, default gateway, internet connectivity, and DNS step by step.

Approach:
Used a logical troubleshooting path to isolate the actual cause instead of restarting everything randomly.

Outcome:
Identified the likely failure point and restored connectivity using a structured troubleshooting method.

Problem:
The internet was working normally, but one Windows PC had no internet access while other devices remained online.

Diagnosis:
Checked the affected PC layer by layer — IP configuration, gateway connectivity, external internet access, and DNS resolution.

Approach:
Used a logical troubleshooting path instead of restarting the entire network.

Outcome:
Isolated the problem to the affected device and identified where the connection path was breaking.
