Wireless: Frequently Asked Questions (FAQ)



Visitor wireless service


General FAQs


Who may use the wireless network?

All students and staff of Cardiff University who register their devices with Information Services and visitors from participating eduroam establishments.


How do I connect to the wireless network?

Please visit the wireless web pages for students, staff or visitors for details on how to connect.

Please note that when connecting to eduroam, your password will be case sensitive.


How long will my registration to eduroam last?

Your access to eduroam should remain for as long as you are a member of Cardiff University.


How fast is the wireless network?

The Cardiff University wireless network operates at up to 150Mbps and is a shared access medium.

This means that as more people connect to the same access point, the wireless speed may become slower to compensate for the weaker signal.

Encrypted transmission will also affect the speed when using the high security service eduroam.


Do I have to pay for a wireless connection?

No. Connection to the service is free of charge for all members of Cardiff University.


Can I use wireless printing in University Residences?

No. If a user were to set up a wireless point for printing this printer would become visible through the network to all of the other students in their hall, and adversely impact upon the wireless service that Cardiff University offers to students.

The user can connect to the printer using a cable, either by connecting it to the outlet in their room - if it supports Ethernet connectivity - or through USB, if their device is a laptop with a suitable USB port.  


Will I be able to access the networked printers from my wireless laptop?

The webPrint wireless printing service enables users of the networked chargeable printing service to send print jobs from their laptop or PC to printers in various locations across the University. Please see the webPrint web pages for further information.


I am connected to the wireless network but I am unable to access the Internet. What should I do?

First check that you are indeed connected to to the wireless service. There are other private wireless networks on campus that are not under the authority of Information Services - access to those areas may be restricted.

For further assistance, please contact the IT Service Desk or visit the IT Clinic in the Students' Union.


I'm a visitor from another university, can I connect to the wireless network?

If you belong to a university or organisation that is part of the eduroam federation, then please use the eduroam wireless network. Instructions and information are available on the eduroam web pages.

Conference and other academic visitors may be entitled to use the Visitor Wireless Service.


My university or organisation is part of the eduroam federation, but I cannot connect. What should I do?

To access eduroam, you will need a username and password from your participating university or organisation.

If you have any problems using the eduroam service, please contact your home institution.

Should I be concerned about security?

Yes. Please refer to the Computer Security and Virus Protection web pages for information and guidance on securing your laptop or PC with anti-virus software and firewalls.


I can see other wireless networks on my wireless device. How do I connect to them?

Only "eduroam", "CU-Wireless" and "CU-Visitor" wireless networks are operated and maintained by Cardiff University Information Services.  Do not try to connect to any other network unless you have been authorised to do so by the person responsible for that wireless network.


Are there any restricted sites?

A number of Bittorrent websites, aimed solely at the sharing of copyrighted material, are blocked from the network.  These sites should have no legitimate access requirements.
