This study proposes the design of a structured network infrastructure to address the persistent challenges of file mismanagement, data loss, and connectivity issues due to IP address conflicts faced by JPS Interior Designs. The solution features a centralized main server with backup capabilities, firewall protection, wireless connectivity for non-Ethernet devices, and controlled website access to improve data reachability and mitigate security risks. The survey results demonstrated consistently high ratings across system quality metrics—including functionality, usability, reliability, performance, and supportability—indicating strong alignment with the operational needs of JPS Interior Designs staff. The proposed network infrastructure addresses key organizational challenges such as file mismanagement, data loss, and unstable connectivity through a centralized file storage system supported by a portable cloud server and a dual-server setup for redundancy and security. The integration of FortiGate firewall security and web filtering enhances protection against external threats, while expanded Wi-Fi coverage ensures broader device accessibility. Overall, the project offers a comprehensive, phased solution that improves operational efficiency, strengthens data integrity, and supports business continuity.
