wifi instable ubuntu 13.04

Bonjour,

Je viens d'installer ubuntu 13.04 en dual boot avec win 8. Ma connexion wifi est instable alors qu'elle est nickel sous windows. J'ai tapé différentes commandes que j'ai trouvé à droite à gauche et j'ai installé wicd sans résultats améliorés. Je n'ai pas l'impression d'avoir fait de bêtises non plus : pas de bug apparent.

Par instable j'entends connexion très faible par moments ou alors un débit de 65 Mb/s indiqué dans "informations sur la connexion" mais des pages qui chargent pas. Je dois déconnecter reconnecter pour que ça marche. Pas facile non plus de voir tout de suite si c'est amélioré après une modif parce que c'est aléatoire.

Sinon ça déconne plus dans une pièce plus éloignée de ma freebox où j'ai une barre en moins (alors que là bas sur windows ça marche toujours nickel). Ca m'énerve parce que j'étais content de me débarrasser de cet horrible windows 8, mais pour l'instant je galère plus sur ubuntu.



Merci d'avance à ceux qui voudraient bien prendre un peu de temps pour m'aider.

Re : wifi instable ubuntu 13.04

Autre chose : quand je démarre il ne se connecte pas à mon réseau systématiquement, mais souvent au réseau freewifi qui ne nécessite pas de clé. Un peu d'aide quelqu'un? Pourquoi ma cart wifi fait des siennes? D'habitude soit ça marche soit ça marche pas...Je comprends pas ce côté aléatoire.

Re : wifi instable ubuntu 13.04

Ah oui. J'oubliais il y a aussi une question de force du signal. Sous windows oui j'ai 5 barres à proximité et 4 ou 5 dans la pièce plus éloigneé. Sous Ubuntu 3 ou 4 à proximité et 2 ou 3 dans la pièce éloignée. Personne pour m'aider ???!!!  Ca à l'ai moins urgent que quelqu'un pour qui ça marche pas du tout mais c'est très bloquant.
Je ne veux pas que ma première expérience linux soit un échec. Et ça rend le travail online tellement pénible que c'est plus simple de me farcir Win 8...

Re : wifi instable ubuntu 13.04

Salut,

Commence par un truc simple : change ton cryptage/chifffrement pout soit que du WPA PSK/TKIP, soit du WPA2 PSK/AES .N'oublie pas d'enregistrer les changements (attention la deconnection si tu est connecté en wifi, faudra se reconnecter) et rebooter la box.

Je vois pas trop le rapport, si ça marche sous windows, et pas sous linux, c'est bien qu'il y a des lacunes avec les drivers linux, non ?
Se contenter de répondre "c'est pas recevable", ça revient juste à ne pas assumer ces lacunes en essayant de les planquer sous un tapis roll

Se contenter de répondre "c'est pas recevable", ça revient juste à ne pas assumer ces lacunes en essayant de les planquer sous un tapis roll

Non, rien a voir.... c'est juste que je vois trop souvent la comparaison entre le 2 OS qui pour rappel, même si il font grosso modo la meme chose (faire fonctionner un pc), mais il sont radicalement différents de A à Z de la conception, au devellopement et en passant par le support fourni par les constructeurs,....donc pour resumer je disais simplement que si l' on veut faire une comparaison il faut la faire sur 2 chose semblables, pas sur 2 choses différentes

Sinon, je suis bien d'accord avec toi : il y a des lacunes avec les modules sous ubuntu mais il ne faut pas se tromper de coupable. Les modules "a problemes" sont tres souvent les modules dont les sources n'ont pas été fournis par le constructeur, et que les dev soient obligé de se demerder de A à Z, mais ce n'est pas leur faute, ni la faute d'ubuntu, mais bel et bien du constructeur qui ne joue pas le jeu du libre.
