What does ÉCLAIR provide?
After paying your membership fee, you are automatically allowed to use the wired plug in every
room in the dorms. For Adoma residents, only one of the two plugs works.
These are the steps you must follow (only once!) so that your computer authenticates itself to the
network.
The instructions are on the following pages, it depends on your computer.
It doesn’t work !
Double check the steps. Your credentials are the same as the ones you use to read your mail. Did
you change it recently?
We sometimes issue custom credentials. These logins always use lowercase characters (only the
login, not the password).
Windows users, please check if you correctly unticked “Validate server certificate”.
Sometimes, the network can block the plug if it receives too many incorrect credentials. Please
wait 15 minutes before trying again.
The network plug may be broken: try connecting in another room (with your computer and your
cable). Your Ethernet cable could be faulty: try borrowing another one. ÉCLAIR also sells Ethernet
cables.

If it still doesn’t work, pay us a visit with your computer and your cable.
