Si j'éteins mon ordi, il est probable que je mette du temps avant d'avoir à nouveau une connexion Wi-Fi, je préfère ne pas le faire tout de suite.
Quand j'aurai éteint mon ordi et à nouveau ce problème, je ferai un nouveau wificheck pour voir les résultats en cas de problème, et quand par miracle j'arriverai à avoir à nouveau une connexion Wi-Fi je posterai les résultats.
