See below for a list of services that are available via the eduroam wireless network in UCD.

eduroam (education roaming) is the secure, world-wide roaming access service developed for the international research and education community. It's used to describe an authenticated access network available in UCD and in Universities worldwide. The service provides extended access to logged-in UCD staff, students and visitors from other institutions.

All usernames will have to contain the home institution’s realm name.  Here at UCD our realm is ''.

When authenticating to eduroam you should use where "username" is your UCD Connect username. The realm (the part after the "@") is always "" for both UCD staff and students. The password used should be your UCD Connect password.  Any fields labelled "domain" should be left blank

eduroam locations:

eduroam can be used in all locations where UCD Wireless is available.

eduroam Services:

eduroam supports the following network services:

  • Client access for all IP protocols except windows filesharing off campus.
  • IPSEC and GRE based VPN protocols.
  • Inbound access is not permitted (i.e. you may not run a server service). 
  • Full eduroam roaming is currently permitted. 

Using eduroam outside UCD:

Test that eduroam works for you in UCD before you leave. If you can't get it working here, you're likely to have problems elsewhere as well.
Search for (and read) any documentation the remote site has on eduroam before you leave. Forewarned is forearmed.
The remote site may use different network encryption to that used in UCD (e.g. WEP vs WPA2). If so, you will need to change that part of your network configuration.
The authentication part of the configuration is specific to the home institution (UCD) so that shouldn't be changed. It includes the EAP methods (EAP-TTLS-PAP), certificates and server verification. Do not change any of those.
Don't forget to include the realm ( when you're authenticating. Usually this just means using rather than simply username. Note that whilst this may look like an email address, it isn't. The realm is generally not what clients refer to as a domain. Domains should be left blank.
