Internet ne fonctionne que très près du rooter (bon signal du rooter)

Bonjour,

Débutant sous  linux, j'ai installé ubuntu sur un laptop acheté avec mandriva pré-installé. (Brésil)
La cartre RTL8188CE 802.11b/g/n WiFi Adapter (rev 01) de realtek fonctionnait très bien avant sur la distro d'origine, (que j'ai salement écrasé) mais voilà, après avoir installé ubuntu, je suis obligé de rester à quelques mètres du rooter pour avoir internet alors que le signal du rooter lui-même ne faiblit pas si je m'éloigne. Si je m'éloigne à plus de 2 mètres, internet se déconnecte avec le rooter toujours accusé et de bon signal. La connection dure plus ou moins dix  secondes puis se coupe. Si je déconnecte du rooter et reconnecte, me voilà avec dix secondes d'internet supplémentaires... Il m'est tout de même possible de lire une vidéo en streeming mais si je charge un lien pendant la lecture, ça coupe.

J'ai fouillé le net dans plusieurs langues et ai remarqué QUE CE PROBLÈME EST COMMUN, mais que les mecs s'acharnent parfois pendant des mois sans résultat, changent de distro ou achètent une carte externe!

Re : Internet ne fonctionne que très près du rooter (bon signal du rooter)

Salut, j'avais le même problème, et j'ai installé le driver propriétaire de ma carte Wifi (dans sources de logiciels pour 12.10 et 13.04 et pilotes additionnels jusqu'à la 12.04).

Re : Internet ne fonctionne que très près du rooter (bon signal du rooter)

Bonjour,

Juste un petit point de vocabulaire, pour faciliter les recherches des autres utilisateurs du forum en évitant de les induire en erreur : tu as un problème de routeur (le mot anglais étant router), mais le mot rooter s'utilise quand on parle de rooter un smartphone.
Je te suggère donc de corriger le titre de ta discussion.

Re : Internet ne fonctionne que très près du rooter (bon signal du rooter)

@cqfd
Merci de votre intervention.

Le problème, c'est que vous n'avez pas lu le message.
En effet, je n'ai pas de problème de routeur, ni de router, quand bien même de rooter.

J'ai un problème de pilote.

Prompt à corriger les autres, ce qu'il falait ne fut pas démontré.
Il est possible que les nouveaux-venus dans l'univers linuxien ne méritent que ce type d'attention, finalement.

Merci quand même.

Re : Internet ne fonctionne que très près du rooter (bon signal du rooter)

Faut pas le prendre sur ce ton là !

Non, effectivement, je n'ai pas lu ton message, je souhaitais juste que ton titre n'induise pas les autres utilisateurs en erreur.

Et je ne cherchais pas à démontrer quoi que ce soit.
