Connecting to the Internet for study, social, and leisure is essential in hostel life. Over the years, ITSC has been managing ResNet services to provide residents with simple, speedy, and secure Internet access.

Designed decades ago when all learning and computing resources were located on-campus, ResNet offered unparalleled speed and convenience compared to accessing the same resources from outside. Today’s widespread adoption of cloud technologies has moved some resources to external data centres, most of these resources can be accessed through any Internet connections.

ITSC has been working close with student hostel management in reviewing the Internet service provisioning. Adopting Internet Service Provider (ISP) solution is an option after year of consultation, evaluation and tendering. The final decision would be made by corresponding student hostel management.

Under ISP provisioning, hostel residents can connect their computer into port via a network cable for the best performance. Besides, they could also bring a router, plug it in, and enjoy their WiFi connections. In addition, they can continue using the CUHK1x wifi service at communal areas in hostels .

By switching ResNet to an external ISP, students can enjoy:

  • 24×7 frontline support
  • Flexible choice of routers to meet personal needs
  • Connection to home-based network devices such as a smart TV.
  • Cross-device continuity features, such as Apple’s Handoff, to increase productivity
