• Applied all available firmware updates on the router and both network switches to address any latent bugs or security vulnerabilities.
• Rebooted devices in a controlled sequence to avoid downtime.
• Revalidated WAN connectivity and ensured all network traffic resumed normal operation.

Outcome:

• WAN2 connectivity successfully restored.
• Firmware across all devices now running the latest stable release.
• Network stability and redundancy confirmed through testing and monitoring.

Next Steps:

• Continue 24-hour observation via monitoring tools for link stability and performance metrics.
• Schedule follow-up firmware audit across the remaining network assets within 7 days.
