What is ResNet?

The Residential Network (ResNet) is one of ITSC’s major services for students residing in student halls. This part of the campus network enables users to check e-mails, submit assignments, view online course notes, search library catalogs, reserve reference books, surf the Internet for academic research, or view a live video broadcast of campus events such as distinguished lectures.

You can also write your own blogs or tweets, log in to Google+ or Facebook to interact with friends, listen to online radio, and watch your favorite YouTube videos or TV broadcasts during your free time.

Wired ResNet and Wireless ResNet are available, both employing the latest network technologies to ensure high-quality and reliable services. Wired ResNet is useful if you are running applications which demand high bandwidth or for fixed Internet device, i.e. device that always connects to the same wall outlet. Wireless ResNet is useful if your internet device does not have a network port, your applications do not demand high bandwidth, you need immediate network access for short time durations such as to check e-mails or read news, or you are located in an area where Wired ResNet is not available.

ResNet Coverage

At present, ResNet connects Undergraduate Halls I-IX, SKCC Hall, University Apartments Towers A-C and Jockey Club Hall in TKO. Wireless ResNet broadcasts the same SSID (eduroam) as the campus Wi-Fi service and is available in all hostel rooms and public areas, such as common rooms and canteens. Wired ResNet provides over 5,000 in-room connections, offering each hall resident a dedicated 100 Mbps switched Ethernet network connection point.

Getting Connected to ResNet

There are two methods to connect to ResNet:

             The Wired ResNet provides wired network connectivity on computers and other devices in Student Halls.

             The Wireless Resnet provides secure, wireless network access in Student Halls.      

Wired ResNet

You need to register your computer or device by one of the two Wired Network Registration Systems to connect to Wired ResNet.

A. New Network Registration System (NetReg)

B. Wired ResNet Application System

The choice of the Wired Network Registration System depends on the Student Hall Location, which is shown in the following table:



Wired ResNet Application System
Undergraduate Hall I  
Undergraduate Hall II  
Undergraduate Hall III    
Undergraduate Hall IV  
Undergraduate Hall V  
Undergraduate Hall VI  
Undergraduate Hall VII  
Undergraduate Hall VIII  
Undergraduate Hall IX  
SKCC Hall  
University Apartments Tower A  
University Apartments Tower B  
University Apartments Tower C  
Jockey Club Hall in TKO  

The following table highlights the major differences on the two Wired Network Registration Systems:

A. New Network Registration System (NetReg)

NetReg is a new Network Registration System to simplify and automate the registration of devices connecting to the Wired ResNet Network.  At first phase, NetReg is available in Student Halls upon the completion on the wired / wireless network upgrade.  NetReg is expected to be available in the rest of Student Halls by End of 2017.

    To register a device automatically

  1. Connect your computer to the wall outlet
  2. Open a web browser and enter the web address netreg.ust.hk, an ITSC Network Registration Page will appear
  3. Enter your ITSC username and password
  4. Read the acceptable use policy and click "Register" to complete the registration
  5. Wait for a few minutes and reboot your computer

    To register a device manually

    You need to use manual registration if your device does not support web browser, e.g. printers and game consoles.

    To ADD device registration:

  1. On any computer already connected to the HKUST netwrok, open a web browser and enter the web address netreg.ust.hk/manualreg.php
  2. Enter your ITSC username and password
  3. In the left navigation, click "Manual Registration"
  4. Enter the MAC address of the device (see the manufacturer's instructions to find the device's MAC address)
  5. Click "Submit" to complete the registration
  6. Wait for a few minutes and reboot your device

    To DELETE device registration:

  1. In the left navigation, click "Registered Devices"
  2. View the registrated devices associated with your username
  3. Click the "X" button next to the registration record you wish to delete

B. Device Registration using Wired ResNet Application System

  1. Locate your wall outlet port number

    The wall outlet port no. for this port is U382.                     

    The wall outlet port no. for the port at the left-hand side is U383 and the port at the right-hand side below is U384.

  2. Determine the MAC address of your device
  3. Register your device using  Wired ResNet Application System
  4. Follow the instructions on the screen, enter your MAC address and wall outlet port no. when prompted

    Once the registration process is completed, it will take a few minutes before you are able to connect to the network.

Wireless ResNet

In order to connect to Wireless ResNet:

  1. You must have an ITSC network account.
  2. The Internet device must support WPA2 (preferred) or WPA.

In general, newer operating systems (e.g. Windows 7/8/10, MacOS and iOS) can search for Wireless ResNet and configure themselves automatically. With older operating systems, you will need to pre-configure the device. Refer to our Configuration Guides for details.

Do’s and Don’ts

ResNet facilitates students’ normal academic activities at the University. We expect users to follow the behavior rules below:


  • Ensure that your machine is properly configured so that you don’t cause inconvenience to other network users
  • Obtain the appropriate software licenses for your machine as operating systems are not provided by ITSC (and using pirated software is an offense in Hong Kong)
  • Act responsibly in maintaining network security, especially with multi-user systems such as Linux, Windows 7, Windows Vista and Mac OS X


  • Experiment or test network hardware/software
  • Create excessive network traffic and/or broadcast
  • Use network addresses other than those provided by ITSC
  • Set up wireless access points which interfere with Wireless ResNet
  • Create accounts for users other than yourself
  • Provide any services to non-University members
  • Allow network access from any machines outside HKUST

You should also adhere to ITSC’s Acceptable Use Policy.

In emergencies, hall managers are authorized to allow ITSC engineers to access rooms for network maintenance without prior notice to users.

Disciplinary Action

If you infringe any of the above rules, you may face one or more of the followings:

  • Immediate termination of your subscription
  • Suspension of your ITSC network account and other ITSC Internet resources

The ITSC Director reserves the right to determine the severity of the infringement.
