беспроводное соединение
Начиная с получения маршрутизатора Linksys E900 Ubuntu 12.04 не соединится, тот же ноутбук (двойная загрузка), которую Windows 7 действительно соединяет, тот же ноутбук, другой дом, который действительно соединяет Ubuntu. первый маршрутизатор встроенное микропрограммное обеспечение Linksys E900 10.0.03, второй маршрутизатор встроенное микропрограммное обеспечение Linksys E1500 10.0.0. Беспроводной картой является Broadcom, и драйвер установлен. Я думаю, что существует что-то в обновлении микропрограммы, которое должно быть обращено в программном обеспечении администратора сети. Безопасность обоих маршрутизаторов WPA2 Персональный. Помогите.

Я выполнил команды и перезагрузил и все еще никакое соединение, посмотрите терминальный вывод ниже:

Я считаю, что драйвер wl не подходит для вашего устройства 14e4: 4727. Пожалуйста, откройте терминал и сделайте:
sudo modprobe -r wl
sudo apt-get remove --purge bcmwl-kernel-source
sudo modprobe brcmsmac
Ваша беспроводная сеть должна работать сейчас; однако, это может занять перезагрузку.
