Pas de connexion WIFI
Oui, je sais, ce forum regorge de personnes désespérées comme moi qui n'arrivent pas à se connecter à Internet par le WIFI. Comme pour beaucoup, seule la connection filaire marche.
Bien sûr, je ne suis pas resté les bras croisés et j'ai fouillé Internet à la recherche d'une solution miracle. Evidemment, j'ai vraisemblablement fait des conneries.
Tout d'abord, j'ai installé WiFi-Radar mais ce programme n'ouvre même pas.
J'ai installé également Wireless Network Drivers (Pilotes Sans Fil Windows) et à travers ce logiciel j'ai installé le pilote RTL8187B car d'après le constructeur de mon ordinateur portable, c'est le bon pilote (modèle de l'ordinateur M761SU). Bizarrement, le logiciel indiquait que le pilote au niveau du hardware était OK mais même comme cela, ça n'a pas marché. J'ai laissé tomber et ai désinstallé dans le logiciel le pilote.
Enfin, j'ai essayé d'installer MadWifi mais sans succès.
En conclusion, j'aimerai arrêter de faire des conneries et de fouiller Internet pour rien, et qu'une âme intelligente et gentille me sorte de ce mauvais pas! MERCI BEAUCOUP!!!;)
Voici les données de mon ordinateur portable:

Re : Pas de connexion WIFI
Et bien non!!! J'ai débranché la connexion filaire et là, plus de net! Si je rebranche le cable, Internet ne revient pas. Alors j'ai redémarré et... surprise, pas de connexion sans fil disponible!
