Connexion wifi défaillante pc neuf.
Bonjour,
Mon pc, Packard Bell Ipower GX-DM 195 FR, est en dual boot avec windaube 7 et Lucid. Ma connexion wifi sous Lucid est très lente par moment et finit par ne plus fonctionner du tout. Parfois même après un reboot c'est pareil.
Sous windaube, elle fonctionne normalement, ça fait une semaine que je tourne avec (quelle galère ) et je n'ai jamais eu de soucis.
Je poste çi dessous les commandes demandées en espérant avoir une aide. Pour ne pas polluer, je n'ai pas mis le résultat du scan, il est très important.
Merci.

Re : Connexion wifi défaillante pc neuf.
wahoo....que de borne autour de toi...dont quelques une sur le même canal que toi, ce qui a mon avis doit polluer ton wifi...
Commence donc par changer de canal pour un canal ou il y a personne et si possible personne non plus sur les canaux adjacents (x+1 et x-1).... oui je sais cela va pas être évident pour la 2 em condition.
PS : la gestion du wifi sous Ms et sous ubuntu est complètement différente et donc incomparable.
