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.

  • Your wireless card 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 wireless card meets this requirement.
  • Your wireless card must support Wi-Fi 4 (802.11n) or later.

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