How do I connect to the TCDwifi network?

Step 1: When you are in range of a wireless hotspot in Trinity you will see 'TCDwifi-firststeps' listed as an available Wi-Fi network. When you connect your device to TCDwifi-firststeps you will be given configuration instructions for connecting to the 'TCDwifi' student Wi-Fi network.

TCDwifi-firststeps also contains links to profiles which will automatically connect Windows and iOS devices to TCDwifi as well as instructions detailing the connection process for all supported operating systems.

If convenient, you can configure your device in advance of coming to campus by following the connection process guide. Once you have configured your device to connect to TCDwifi it will automatically connect whenever it is in range.

Step 2: The next step after configuring your device to connecting to the Wi-Fi network, is to run a security scan to register your device and ensure that it is up to date. Launch a web browser and browse to any external site* such as http://www.irishtimes.com and you will be automatically redirected to the TCDconnect registration pages, where you can download and run the scan. When the scan completes a results page will be displayed.  If your device passes the scan then you will be connected within 90 seconds.

The process for registering for the student wired and Wi-Fi networks is identical and once you register your device on one it will automatically be registered on the other.

*Please note the external site you chose to connect to must be http:// and not https:// - otherwise you will see a "site is private" message when trying to connect.

How do I connect to the wired network in residences?

Step 1: TCDconnect wired network in student residences only. Insert a network cable into the network point in your room and the network port on your computer. You should see a flashing activity light on your computer’s network port when connected. A network cable (also called an ethernet cable) can be purchased from the students’ union shop. (There is an entirely separate process for postgrads connecting computers to the wired network in Trinity offices and labs.)

Step 2: The next step after connecting to the wired network is to run a security scan to register your device and ensure it is up to date. Launch a web browser and browse to any external site* such as http://www.irishtimes.com and you will be automatically redirected to the TCDconnect registration pages, where you can download the scan and register your device. When the scan completes a results page will be displayed.  If your device passes the scan then you will be connected within 90 seconds.

The process for registering for the student wired and Wi-Fi networks is identical and once you register your device on one it will automatically be registered on the other, so if you have completed the process on one network (wired or Wi-Fi) then you will be automatically registered and ready to connect to the other.

*Please note the external site you chose to connect to must be http:// and not https:// - otherwise you will see a "site is private" message when trying to connect.

 

General requirements

Who can connect to TCDconnect?

  • Students can connect to the TCDconnect service once they have completed online registration at my.tcd.ie, and have a valid Trinity username and password.
  • New students should note, that you are provided with your Trinity username and initial password in an in-tray message on your my.tcd.ie portal, once you have fully completed online registration there.

What are the TCDconnect hardware and software requirements?

Only certain devices are supported on the TCDconnect service, as outlined on the TCDconnect general requirements page.

Why are the security requirements necessary?

By requiring that all Windows laptops have the latest updates the chances of a virus outbreak on the TCDconnect wired and Wi-Fi networks are greatly reduced. The TCDwifi network is hidden and encrypted so that only Trinity students can connect to it.

Although open, unencrypted networks are easier to connect to they are not as secure and any information you submit online could be intercepted. You can read more about the benefits of the TCDconnect NAC system.

Those using smartphones and tablets are required by policy to set a passcode lock, password or PIN for the device.

My device is not running a supported operating system or antivirus program; can I still try to register it?

Only the devices listed on our requirements page can register for the TCDconnect service. IT Services is working to expand the range of supported devices.

However, devices not listed on the requirements page cannot connect currently and if your device has an unsupported operating system or antivirus program you will not be able to register the device.

How do I install Windows updates?

To begin the update process please follow the instructions on installing Windows updates .

When running updates it is important to leave your computer connected to a power supply and not to interrupt the update process. After installing the updates, reboot your machine and run the updates option again. Some updates are prerequisites of others so you may have to run the update process multiple times. You should continue to update your computer until there are no new important updates available.

As updates can take some time to download and install, it is recommended that you check and complete this process before you get to campus and attempt to connect to the network or make an appointment at the Network Clinic.

If you are viewing this page at home and have run the TCDconnect remote registration you will be provided with instructions on how to update your operating system if necessary.


Security scan & registration

What does the security scan check for on my device?

When you connect to TCDwifi you will need to download and run a ‘Bradford Dissolvable Agent’ which will scan your device to ensure that it meets the TCDconnect requirements. These requirements vary by device:

  • iOS, Android, Linux, Chrome OS and Kindle: there are currently no minimum requirements for these operating systems; once you submit your details your Android, iPhone, iPad, iPod Touch, Chromebook or Linux device will be automatically registered

  • macOS: the scan checks if your laptop is running a supported version of macOSX.

  • Windows: the scan checks that your version of Windows is up to date and that your computer has a supported antivirus program which is also up to date.
    • For example, if your computer has Windows 7 the scan will check that it is has Service Pack 1 installed as well as the latest security updates. If you have Microsoft Security Essentials installed as your antivirus program it will check that it has the most recent virus definitions.

If your device’s operating system is not listed on the requirements page or your computer is running a preview/beta version of Windows it cannot be registered for the service.

How can I ensure I pass the remote registration scan?

All Devices: Ensure you have a supported operating system running on your device

If you have a Windows PC

My computer failed the security scan. How can I resolve this when I don’t have full access to the internet on campus?

When the scan completes a results page will be displayed. If the scan is failed then you will be shown a list of failed items that require action – double-click on any of the items on this list, click the link that is displayed under that item and follow the instructions provided in order to update your computer before running the scan again. 

The registration system allows you to connect to certain websites such as microsoft.com and apple.com so that your computer can download any required security updates. It also allows antivirus programs to download the latest virus definitions if necessary.

Do not choose ‘Rescan’ until you have followed the steps to correct each failed item.

Why do I get an error message when I try to run the security scan?

The scan may not be compatible with your browser, try accessing the scan with Chrome or Firefox.

It is also worth noting that the security scan will expire after a certain period of time. After it expires if you try to run it you will get the message "Unable to read policy. Please check your personal firewall settings and try again." If this happens please resubmit your details via your browser to download a new copy of the Bradford security scan.

The scan timed out or did not complete, what do I do now?

If this happens please restart the registration process and re-download the security scan

Sometimes your antivirus may interrupt the scan process, if your scan times out, please try turning off your antivirus before you re run the scan. Making sure to turn it back on again once complete.

I have setup my computer to connect to TCDwifi but I don’t see the TCDconnect Registration page when I open my web browser

Some websites do not redirect to the TCDconnect Registration page.  If you have entered the settings for TCDwifi and do not see the TCDconnect registration page when you open your browser then try visiting http://www.irishtimes.com.* 

It could also be worth trying another web browser such as Google Chrome or Mozilla Firefox.

*Please note the external site you chose to connect to must be http:// and not https:// - otherwise you will see a "site is private" message when trying to connect.


Connection process

I am able to connect to the Wi-Fi in some areas in Trinity, but not in others

In some specific cases those using Windows laptops may experience issues connecting to Trinity Wi-Fi services when in 'High-Density' Wi-Fi locations. See our page outlining this Wi-Fi connectivity issue in High Density Wi-Fi locations for advice on how to resolve this issue.

If you have followed the steps provided in the link above, but are still experiencing connectivity issues, please email itservicedesk@tcd.ie and advise of the nature of your issue, your device type and operating system, the frequency and time of the connectivity issue and your location when experiencing this issue.

Why does my laptop keep joining the wrong wireless network?

Network order

Windows and Mac OS X keep a list of preferred wireless networks. They attempt to join these networks in the order they appear on the list. If either TCDguest or TCDwifi-firststeps are listed above TCDwifi then the laptop will attempt to join these first and will not connect to TCDwifi.

In Windows 7 the order can be changed by clicking on Manage Wireless Networks in the Network and Sharing Centre (via the Control Panel).
In Windows 8/10 you can click on the Wi-Fi icon in the bottom right and then click on any Wi-Fi network you do not wish to connect to and untick ‘Connect Automatically.’

In Mac OSX it can be changed via the Advanced settings of Airport/Wi-Fi (via System Preferences).

Your laptop may also try to connect to another network if TCDwifi is not correctly configured. If this is the case please connect to TCDwifi-firststeps and follow the configuration instructions there.

I cannot connect to TCDwifi on my Linux laptop - why does TCDwifi keep prompting for my username and password?

Some versions of Linux have an issue connecting to some WPA2/PEAP/MSCHAPv2 networks like TCDwifi. To resolve this issue please remove the line 'system-ca-cert=true' from the configuration file in /etc/NetworkManager/system-connections/

Please see the following link for further details: http://askubuntu.com/questions/279762/cant-connect-to-wpa2-enterprise-peap. Please note we cannot provide assistance with changing these settings on Linux laptops if you encounter any issues with these instructions.

Why does Windows 7 keep prompting me for my username and password when I try to connect to TCDwifi?

On some laptops an additional step may be required before you can connect to the network.

  • Click on the wireless icon in the bottom right.
  • Right click on TCDwifi and select Properties.
  • On the security tab click Advanced Settings.
  • Tick Specify Authentication Mode and select User.
  • Click on Save Credentials and enter your Trinity username and password.
  • Click OK twice to close the windows.

Your laptop should now connect to TCDwifi automatically.

Login prompt

My Windows 10 device will not connect, why?

In a small number of cases where this happens, it has been resolved by upgrading the wireless card device driver. If you wish to do this, please visit the website of your wireless card manufacturer for instructions.


Mobile devices

How can I uninstall the mobile device profile and disconnect from this service?

Follow the removal steps for your device:

How can I remove the passcode lock?

You must have a passcode lock to use this service. If you wish to disconnect from the service and remove the passcode lock please see the steps above.

I am having some problems getting connected - Safari won't show any web pages

If Safari can't access a webpage after completing the connection process, then please try the following:

Open the Settings app, choose General, then Network, then Wi-Fi, TCDwifi. Under DHCP settings, if you have an IP address that starts with 169 or if you have no IP address specified then scroll down the screen and select the Renew Lease button which should return a valid IP address and should restore your network connection.

What should I do if my device is lost or stolen?

If your device is lost or stolen and you had previously configured it for connection to the TCDwifi network and do not have a passcode set for your device, IT Services would advise you to change your Trinity network login password to avoid the potential for a third party to gain unauthorised access to the TCD student Wi-Fi network via your device.

Can I access MyZone email on a mobile device?

Configuring your mobile device to connect to an email service should function correctly. If configuring an iPhone/iPad/iPod Touch to connect to MyZone you would access the Settings app, choose 'Mail, Contacts, Calendars', choose 'Gmail' and enter the details as below. Please note that no support for this functionality is available from IT Services.

Printing

How do I print from the TCDconnect service?

All students can use the TCD Print Anywhere service, whether connected to the TCDconnect service or not, to print to the Datapac printers in the College Library and computer rooms from their laptop or mobile device.

Getting help

I am having difficulties connecting my device to the network, where can I get help?

IT Services runs a TCDconnect network clinic at the IT Service Desk, in Áras an Phiarsaigh from 11am to 3pm, Monday to Friday. 

You can bring your laptop or mobile device if you need assistance with the connection process, you will need to take a numbered ticket from the ticket dispenser when you arrive and wait for your number to be called on the overhead display.

See our network clinic page for information on what to do before you arrive, and what to bring to the network clinic.

If my laptop has a hardware or software issue can I get help with it in the Network Clinic?

The TCDconnect network clinic can only provide support with the process of connecting your device to the wired and wireless networks. Neither the Network Clinic nor the IT Service Desk in Áras an Phiarsaigh can assist with other hardware or software issues on personally-owned machines. If there is an issue with your laptop which prevents it from connecting to the network (such as a faulty wireless card or damaged operating system) the Network Access Advisors in the clinics can provide general advice but cannot repair your laptop.

Click.ie run an on-campus IT repair centre for staff & students’ personal equipment.

I'm having trouble accessing some online services - which services should I be able to access using TCDconnect?

I am connected to TCDwifi, but I cannot reach any other pages.

When in Trinity only the Trinity DNS settings will allow internet access.  Custom settings, such as the Google DNS (8.8.8.8), will not work.  It is necessary in these cases to clear the custom DNS setting from your device.

I was connected to TCDwifi, but I can't connect since I installed Windows Updates.

This will only work for students whose device is registered and have previous connected to TCDwifi.
Sometimes Windows Updates can interfere with your connection, reboot your device more than once to ensure all settings are refreshed and you should be able to reconnect.

I was connected to TCDwifi earlier in the year, but I can't connect now.

If you do not use the TCDconnect service for 40 days you will need to re-register for the service and you will be able to connect again.
