More about eduroam?

Eduroam net is a safe net, from which you can access to all UL resources available. This net isn’t visible, it must be manualy configured. After the 802.1x connection is successfully established on eduroam net, one must establishes a new VPN connection to access to UL internal resources.

Software/Hardware requirements

For the 802.1x access the following requirements are needed:

• Wireless hardware component that supports 802.11b (see www.weca.net ).
• Login user on the UL authentication system.

VPN Access

To access through VPN to the wireless net, it is necessary to have at least the following requirements:

• Login user on the UL authentication system.
• Windows XP/2000 (*) operating system.
• 802.1x connection previously established.

* Nota: Eventually it can be possible to establish a connection on other operating systems, but the ones mentioned before were tested and approved by our technicians."eduroam", when nothing seems to work... (Windows XP)!!!

There are quite a few reasons, here are a couple of them:

--> 802.1x protocol is not being consider (EAPOL-START is not starting)
--> Our technicians must install again the operating system

--> Some times, after several attempts without a successful login (incorrect password or login) to "eduroam", even though it is configured, it just disappears on the visible nets
--> There are quite a few ways to solve this issue::
- restart
- delete "eduroam" and configure it again
- Unplug/Plug the wireless net component

Note: Keeping in mind all the tests made and the solutions found until now, we can in the near future give other alternative solutions. Therefore, here are a couple of possible solutions for the previous problems detected.
