If Keflavík Airport Wi-Fi is not working, verify the official network before changing anything else. KEF currently names it KEF – FreeWiFi and says no registration, login or password is required.
An unexpected payment, certificate or software-installation request does not match that description.
This is a Wi-Fi recovery task; cellular APN settings are unrelated.
Quick answer: Check the exact SSID, toggle Wi-Fi once, forget and rejoin the official network, open a plain webpage, and use saved details or mobile data if the connection still fails.

- Confirm KEF – FreeWiFi exactly.
- Close unexpected payment or installation prompts.
- Turn Wi-Fi off and on.
- Forget only the official network and reconnect.
- Open a plain webpage to trigger any system network check.
A VPN or private DNS can interfere with public networks; change it only when policy permits and the security consequence is understood. The official KEF Wi-Fi guide covers safe use.
Use the Prepared Fallback
Open the offline transfer and accommodation details. If an eSIM is already installed, test it through the KEF activation card. Do not accept an unverified hotspot merely because it has a similar name.

FAQ
Should KEF Wi-Fi request payment?
No. The airport currently describes the official network as free with no registration or password.
Will changing the eSIM APN fix airport Wi-Fi?
No. Wi-Fi and mobile-data APN are separate connection systems.
Final Recommendation
Verify the official SSID before attempting recovery.
Use only narrow Wi-Fi resets and reject prompts inconsistent with KEF guidance.
Move to the offline or mobile fallback rather than weakening device security.
