Below is a list of the general requirements for staff and postgraduates connecting to the wired data network in Trinity offices and labs, and to the staff Wi-Fi service. If you need details on connecting to the student Wi-Fi service or the wired network in student residences then please see the requirements for the TCDconnect service.

General requirements

  • Only holders of valid Trinity usernames can request connection to the teaching and research network

  • In order to use the wired network you must have access to a live network point and you will need a network cable
  • Staff wishing to connect computers to the staff Wi-Fi network should note that a wired connection is required before obtaining a wireless connection - this is not a requirement for mobile devices such as smartphones and tablets
  • Users requiring connection to the Wi-Fi network should be aware that there are wireless network card requirements
  • Staff or postgraduates wishing to connect a printer to the Trinity data network in offices and labs should refer to the web page on network printing

Network adapter requirements

Wired network adapter

In order to connect your computer to the Trinity wired network you will need a network card, also known as an ethernet adapter, in which to connect an ethernet cable. To verify that you have a network card, look at the rear or side of the computer and you should see a port for an ethernet cable. For those computers that do not ship with a wired network card please note there are some specific tested models of USB to Ethernet adapters that are supported on the Trinity data network.

Wi-Fi network adapter

Most wireless network devices with the Wi-Fi Logo should be able to connect to the Trinity wireless network.

Security protocol: Your Wi-Fi adapter must be able to use the WPA2-Enterprise protocol. There is a tool available on the Wi-Fi Alliance website which will allow you to determine if your Wi-Fi adapter meets this requirement. Support for the older WPA1 protocol has been discontinued in order to improve network security.

Staff wishing to connect computers to the staff Wi-Fi network should note that a wired connection is required before requesting a wireless connection. For those computers that do not ship with a wired network card please note there are some specific tested models of USB to Ethernet adapters that are supported on the Trinity network.

If you need further assistance with regards to wireless network card compatibility please contact the IT Service Desk.
