Wifi Faible depuis reinstallation
Salut !!
Petit historique: je tournais sous Ubuntu 10.4 je crois, et en bidouillant des trucs avec les drivers videos j'ai un peu flingué mon installation, et comme je voulais tester mint je me suis dit banco!, et j'ai installé la dernière version de Linux Mint (basée sur ubuntu 11.04).
Mon problème est le suivant, ma navigation sur le web est lente, instable, et lente encore.
Pour info, le p2p marche bien, et sous windows tout marche tranquillement, et je n'avais pas de problèmes avec mon ancienne installation.
Si je regarde le moniteur système j'ai des périodes ou mon taux de download tombe a zero et puis ensuite revient.
Je n'ai pas accès à la box qui est dans l'appart de mon proprio un étage au dessus du mien.
Ça marche un peu mieux dans ma salle de bain ...
Bref ça ressemble à "signal faible" or je ne vois pas le signal wifi bouger trop (je n'ai que 2/3 barres sur 4)
Auriez vous des idées d’où çà peut venir (peut être quelquechose que j'aurais modifiée auparavant dans mon ancienne ubuntu...)
Merci !
EDIT: j'utilise opendns comme DNS

Les ordinateurs, c'est compliqué, les logiciels encore plus...
Après on s'étonne qu'il y ait parfois des problèmes...
Le mieux c'est de continuer à compter avec ses doigts...
