  • How can I use the wired network in my room if my PC/notebook has only wireless adaptor?

    You can use external Ethernet adapter that is readily available in the market.



  • Can I setup my own Wi-Fi router in my study-bed room to share my Internet link among various devices?

    No. CSC does not allow student using a self-own router/ switch/ hub to access the Internet, and SRO does not support student setup self-own router. Connecting network device such as wireless router, switch, etc. to the network port is prohibited because
    a) It will interfere the hostel’s Wi-Fi network and induce network security problems that will affect other users / students on the same floor.
    b) Due to the high density of the study-bed rooms in the hostel environment, Wi-Fi routers will interfere each other and hence degrading the network performance, including both wired and wireless connections, and affecting everyone’s using experience.

    N.B. Do not connect to Wi-Fi network not provided by CSC or SRO. It is insecure to connect to unknown Wi-Fi network and may cause data or password leakage.

    You may turn your PC connected to the Hostel network into a Wi-Fi hotspot temporarily by enabling the “Internet Connection Sharing” (ICS) feature as a workaround solution. You may visit the following URL for more information in setting up the ICS:
