The free network is WIFI-AIRPORT, the same at Charles de Gaulle and Orly. Paris Aéroport describes it as free and unlimited.
- Select it, then accept the terms on the welcome page that opens in your browser.
- Turn off any VPN until you are connected: the welcome page needs to load first.

- It is an open network, so the airport advises using mobile data rather than this Wi-Fi for banking or email.
