TCDconnect - How to connect Apple iOS devices to student Wi-Fi service

To complete the process you must be in range of a Trinity Wi-Fi hotspot (see our Trinity Wi-Fi coverage information) in order to register your device on the TCDconnect service, connect it to the Trinity Wi-Fi network and gain fast, secure internet access. Those using the service are assumed to have read and agreed to the terms and conditions.

Broadly speaking there are three steps to carry out in order to get connected:

  1. Connect your device to the TCDwifi network.
  2. Register your device on the TCDconnect service.
  3. Set a device passcode to protect the security of your device in case of theft or accidental lost.

Your device is now connected to the TCDwifi network and the next step, required before you can get internet access, is to register your device for the TCDconnect service, as outlined below.

  3. Close and relaunch the Safari app and you will have internet access - you are now fully connected to the TCDwifi student network and once you are in range of a TCDwifi hotspot you will connect automatically.

Important to know: If you do not use the TCDconnect service for 60 days you will need to re-register by repeating the steps above.

Step 3: Set a Passcode to protect your device.

In order to prevent unauthorised access to your iPhone in the event that it is lost or stolen follow these steps, if you have not already done so.

  1. On your iOS device, launch the Settings app.
  2. Choose Touch ID & Passcode. Here you can set your Touch ID and Passcode preferences.

Removal Instructions

If you registered your device and now wish to leave the service please follow these steps:

  1. Launch the Settings app.
  2. Choose Wi-Fi.
  3. Choose TCDwifi.
  4. Choose Forget This Network.

Note that IT Services does not recommend that you remove your device passcode lock, as having one helps to protect your device in case of theft or accidental loss and prevents unauthorised access to the TCDwifi network for those devices already configured for the TCDwifi network.
