Bonjour à tous.
Je vous contacte ce jour car je suis actuellement en train d'aider un de mes amis, actuellement expatrié en Amérique du Sud (navette entre le Brésil et le Paraguay) avec qui je communique UNIQUEMENT via smartphone et application "whatsapp" ou par mail dans un cybercafé suite à une panne de sa machine.
En effet, dès son arrivé là-bas, son ordinateur refuse de se connecter en WIFI. Je précise qu'il a là-bas fait changer sa carte WIFI et a même essayé un "Dongle WIFI USB". En revanche, le filaire fonctionne. Le problème bien entendu c'est qu'il ne peut pas disposer de ce type de connexion là-bas ce qui est particulièrement bloquant.
Voila les éléments que j'ai pu collecter pour vous les soumettre et avoir votre avis sur la question:
Type machine:
Modèle LENOVO "THINKPAD" 505GS
Système:
KUBUNTU 14.04 LTS
NOTA: J'ai fait essayé à mon ami via un live CD la distribution 18.04. Peine perdue!... Le problème persiste
Noyau actuel:
3.13.0-135-generic
