probleme wifi ne veut pas se connecter ou super lent
Bonsoir,
J ai un probleme avec ma connexion wifi, je me connecte avec le ndiswrapper, il y a deux jours tout fonctionnait a merveille. mais depuis hier il ne veut plus se connecter ou alors il est tres tres lent.
On a un routeur dans mon appart, tout les reseaux sont identifiés par ndiswrapper mais pas moyen de se connecter, ni au mien (avec code) et pas plus qu a celui du voisin qui a pas mis de code.
On peut faire qqch pour moi ?
Merci d avance
Louis

Re : probleme wifi ne veut pas se connecter ou super lent
Bonsoir,
Je sais pas comment tu l'as installé, mais apparement mal, t'as un module qui gere ta carte en natif : B44.
Or on voit qu'il est toujours present dans le retour du lsmod que tu donne. En gros 2 pilotes pour parler au meme périf : bonjour le bordel.
plutot qu'un long discours, une bonne doc : http://wlety.free.fr/forum/viewtopic.php?id=175
PS : apparement t'as aussi un probleme pour recopier les commandes sous ubuntu qui est sensible à la case (les majuscule et le minuscules) ; la bonne commande qui aurait donné le bon retour était :
sudo lshw -C network
Utilise le copier coller, c'est plus sur 
Tombé dans l'informatique étant petit, j'en ai fait mon métier. Utilisateur d'Ubuntu depuis novembre 2006, actuellement sous 20.04 x64 (Que d'évolution
depuis Dapper Drake ! Ça rajeunit pas ^^^).

Re : probleme wifi ne veut pas se connecter ou super lent
Merci,
Toutefois, J ai réussi a avoir une connexion stable a travers de Wifi-radar...
Cependant si il y a des suggestions pour nettoyer tout ce brol et avoir un connexion sure, propre et nette je suis preneur !
PS : J ai établi ma connexion dés le principes de la même façon que dans ton lien.
