Я установил Ubuntu 16.04 на своем ноутбуке Lenovo B560, но не могу обнаружить мой Wi-Fi, другие устройства могут обнаружить Wi-Fi, этот ноутбук (16.04) может обнаружить другой Wi-Fi в окружении. В настоящее время я использую его с картой Wi-Fi usb.

Решение прибывает из этого сообщения Беспроводная связь BCM4313 на Сервере Ubuntu 12.04

"

sudo apt-get remove --purge bcmwl-kernel-source

Перезагрузка и теперь говорит, загружается ли brcmsmac:

lsmod | grep brcm
