[finalexpression]

Здравствуйте,

Проблема с вай-фаем. Интернет есть только возле роутера на расстоянии метра, но за дверью, уже дисконектит.

У парня такая же проблема - http://ubuntuforums.org/showthread.php?t=2257800

[Lesopoval]

Посмотри, какой хоть на данный момент драйвер используется:
lspci -v

[finalexpression]

Помогла установка http://launchpadlibrarian.net/181487980/bcmwl-kernel-source_6.30.223.248%2Bbdcom-0ubuntu1_amd64.deb
