Staff Wi-Fi - How to connect your iOS device

The information below outlines how registered Trinity staff can connect their iOS mobile device (iPhone, iPad or iPod Touch) to the Staff Wi-Fi network. Should you make use of the service you are advised to read through our web page regarding good IT security practices for those using mobile devices. Those using the service will be asked to agree to the terms and conditions during the connection process outlined below.

Supported devices & requirements

The service is currently available to staff with iPhone, iPad or iPod Touch devices.

This service requires, for security, that you have a passcode lock set for your device. During device registration you will be prompted to set a passcode lock if you do not already have one. The requirement for a passcode lock is to prevent unauthorised access to Trinity's IT systems and your data in the event of loss or theft of the device. It is your responsibility to remember this passcode as if you forget it you will have to do a restore from backup and so may lose data.

  5. Confirm the duration of your device's registration, 12 months, and then follow the instructions to submit your device's Wi-Fi address to IT Services.

  6. Within 10 minutes, you will receive an initial email to your Trinity email address with confirmation that your device registration request has been received. A second email will contain instructions on what to do next, in order to connect to the Staff Wi-Fi service.

    • Open the second email on your iOS device and follow the instructions to install the 'mobile profile' on your device. This will configure it with the correct settings for the Staff Wi-Fi network - enter your Trinity username and password when prompted and, if prompted to 'Accept' the TCDwlan certificate then do so. If you did not already have a passcode set then you will be prompted to set one.

      If you cannot install the mobile profile then follow the instructions below for those not using the iOS Mail app.

If you are not using the iOS Mail app for your Trinity email on the device you are registering:

    • On your iOS device, launch the Settings app.
