On-campus Wi-Fi Connection
CityU Wi-Fi provides high-speed wireless Internet and campus network access covering virtually the entire campus (except for lifts, staircases, toilets, etc). To connect to a CityU wireless network, all that is needed is a device with an 802.11a/b/g/n/ac (Wi-Fi 5) or ax (Wi-Fi 6) wireless card. Users can surf the Internet, check email, and much more from anywhere within the covered areas.
Currently, three types of Wi-Fi services are available for the University community:
CityU Wi-Fi network is solely for CityU members (staff, students and alumni) with CityU EID. CityU members can connect to the network ID (SSID) “CityU WLAN (WPA)” or “CityU Alumni” to gain access to the Internet with higher transfer speed and better performance. Currently around 3,000 access points are installed on campus covering most areas including the University Concourse, lecture theatres, classrooms, Student Residence, etc.
Eduroam stands for "Education Roaming" and it is a worldwide free Wi-Fi service offered by eduroam participants. CityU has joined eduroam since 2008. Eduroam participants including CityU staff and students can connect to the SSID “eduroam” to gain Internet access in all participating institutions worldwide.
Free Wi-Fi service is an initiative of the Government of Hong Kong Special Administration Region for providing free Internet connectivity in many public venues. CityU has joined the initiative to provide free Wi-Fi service to visitors on campus since 2014 and the SSID used is “Wi-Fi.HK via CityU”.
Safety Tips on Using WLAN
Once you have your notebook connected to any WLAN, you are exposing yourself to potential attacks. Therefore, network security and data protection is extremely important, especially when you are using public wireless hotspots. Following safety tips may help you to protect your notebook and safeguard your information while using WLAN:
- Disable resource sharing such as "file-sharing" to avoid any leakage from your computer.
- Disable "Ad-Hoc" mode networking to prevent attackers from easily gaining access to information and resources on your notebook.
- Install and activate personal firewall, anti-virus and anti-spyware program. Apply latest patches and fixes frequently for the OS and programs installed.
- Always use secured connection such as WPA in the WLAN.
- Never leave your notebook unattended, disable wireless connection when it is not in use.
- Avoid performing any sensitive operation such as e-banking, e-shopping, etc. over public WLAN to prevent leakage of your personal information such as bank account number or credit card number.
- If your notebook can make WLAN connection automatically with your stored credentials, then never lend it to others without clearing the credentials.
- Never connect to unknown wireless networks. Attackers could set up fake captive portals to harvest personal information.
