Challenges & Operational Constraints

• Vessel access required coordination with port foreman, resulting in 2 hours of waiting time before boarding.

• Wi-Fi access points could not be reached remotely, which limited final wireless adjustments.

System Status

Notes & Recommendations

• Wi-Fi password should be updated and enforced with stronger authentication.

• A review of Wi-Fi AP accessibility is recommended to ensure full administrative control.

• Captain requested a structured plan to renew all Wi-Fi passwords and monitor crew internet usage.

• No further issues were identified in email, VoIP, or switch performance.

Lessons Learned

• User access control must be periodically reviewed.
  Weak Wi-Fi passwords can cause security and bandwidth management issues and should be refreshed routinely.

• Wi-Fi AP accessibility must be ensured before configuration.
  Difficulty accessing the access points delays troubleshooting and prevents full optimization.

• Remote access setup accelerates IT repairs.
  Early remote access allowed configuration tasks to be completed quickly.

• Understanding crew usage patterns helps improve network efficiency.
  The captain’s request for password management highlights the need for structured access planning.

Service Outcome
