Décrochage sans fil sur un BCM4313
Ma connexion ne cesse de tomber: je dois cliquer sur mon réseau wifi domestique pour me déconnecter et me reconnecter à Internet.
J'ai essayé de mettre MTU à 1500 comme le suggère ce post [1] mais mon sans fil continue de baisser! [1] http://mylinuxramblings.wordpress.com/2011/10/16/how-to-stop-ubuntu-11-10-wireless-dropping-out/
La question suivante ne m'a pas aidé non plus: Comment puis-je empêcher ma connexion réseau Ethernet de tomber?
Ma configuration est la suivante, ubuntu11.10 sur HP Pavilion dv6, wifi à l'aide d'une clé WEP:
$ lspci | grep -i eth

Je suis quelque peu confus; à partir de la sortie de lshw -C network il semble que vous utilisiez déjà le pilote brcmsmac avant la modification:
product: BCM4313 802.11b/g/n Wireless LAN Controller
vendor: Broadcom Corporation
[snip]
configuration: broadcast=yes driver=brcmsmac [snip]
Si c'est le cas, vous devriez essayer le pilote binaire Broadcom STA, qui fonctionne parfois bien mieux que ce post suggère . Vous pouvez l'installer en utilisant jockey-gtk (ou Pilotes supplémentaires dans le menu) ou avec
Sudo apt-get install bcmwl-kernel-source
Vous pouvez vérifier quel pilote est utilisé dans le menu NetworkManager (sous Informations de connexion) ou encore avec lshw - Le pilote STA est appelé wl afin lshw devrait retourner driver=wl (ou wl0) au lieu de driver=brcmsmac. lsmod n'est pas très utile ici car les deux pilotes peuvent être chargés.
