Bonjour
Je suis sur un thinkpad E550 corei3, j'ai un problème de wifi curieuse en sortie de veille, des fois je n'ai pas internet (icone wifi transparent et aucun réseau détecté), des fois les flèches blanches haut et bas comme si j'était connecté en Ethernet, alors que celui-ci n'est pas branché. mais internet fonctionne bien malgré ces flèches, parfois même l'icone wifi tout grisé aucun réseau wifi détecté quand je clique dessus, mais l'accès tout de même bon !!
Dans paramètre système-réseau, si je n'ai pas d'accès, il m'indique hors de porté, sinon, il indique dans tout les cas que je suis bien relié a la wifi de chez moi.
Le problème majeur est lorsqu'en sortie de veille je n'ai pas de réseau. Pour régler le problème, je redémarre ma machine, et comme par magie, le réseau est détecté.
voila les retours de commandes demandées :
