Je me réponds à moi-même :
pas grave, problème de parefeu.
J’ai déconnecté le parefeu et là je poste depuis mon wifi “ricardowifi” avec le cable eth débranché.

[code]ricardo@Dell-sid:~$ sudo iwconfig
[sudo] password for ricardo:
lo no wireless extensions.

eth0 no wireless extensions.

wmaster0 no wireless extensions.

On va donc terminer ici et ouvrir un autre fil pour voir ce qu’il convient de modifier dans le parefeu.
Là, je vais faire appel aux chefs et entre-autres à Pascal.
