WiFi✯

The buildings are equipped with WiFi access points. You can connect to them via the international university network (eduroam network).

Eduroam Configuration✯

A tutorial to connect to the EDUROAM WiFi network is available here: https://confluence.dsi.uca.fr/pages/viewpage.action?pageId=53444956

If it does not work, use the following configuration:

  • SSID: eduroam
  • EAP Method: PEAP
  • Phase 2 Authentication: MSCHAPv2
  • Server CA Certificate: Default
  • User Certificate: None Installed
  • Domain: uca.fr (if requested)
  • Identity: UCA Login
  • Password: UCA Password
  • Anonymous Identity: Empty

Eduroam CAT Configuration Tool

You can use the Eduroam CAT (Configuration Assistant Tool). It is a utility to facilitate connection to Eduroam. It is available for common operating systems (MacOS, iOS, Android, Linux, Windows...)

Go to: https://cat.eduroam.org

  • Click on "Eduroam Users: download the eduroam installer" or "Click here to download your EDUROAM installer"

  • Select the Université Clermont Auvergne or your affiliated university.

  • Click on the proposed installer or choose another one using the link just below.

  • Run the proposed script

Connecting outside UCA

If the connection does not work outside UCA with the Eduroam CAT tool configuration, try filling the Anonymous Identity field with anonymous.uca.fr.

Issues✯

The coverage area is substantial and correct, but several factors cause disruptions based on our observations.

Many students use their phone as a hotspot, which generates congestion on WiFi bandwidths.

WiFi does not guarantee that a client will have access to an access point if another client closer to the access point and consuming bandwidth blocks access.

Quickly, a negative spiral can occur. A user uses their hotspot and blocks others who will then use their hotspot...

Everyone must be responsible and understand that their use of hotspots potentially disrupts others.

The 2.4 GHz frequency band is generally less prone to disruptions than the 5 GHz band.

We are currently testing the performance of access points in relation to their positioning and number.

What to do?✯

  • Ask hotspot users to turn them off while explaining the issue

  • Report the most detailed information possible (date and time, room, issue encountered) via a ticket on support.isima.fr and for students, prefer the Discord server of ISIMA

Tools like WifiAnalyzer (for Android, Windows10) allow you to observe network overlaps and signal quality for each access point

On Linux, you can use nmcli for the same purpose

sudo apt-get install network-manager
sudo systemctl start NetworkManager.service
sudo systemctl enable NetworkManager.service

nmcli -f “IN-USE,BSSID,SSID,MODE,CHAN,RATE,SIGNAL,BARS,FREQ,SECURITY” d wifi
nmcli
