Невозможно использовать беспроводной сетевой интерфейс (Lubuntu Linux 4.8.0)
Я отвечаю за поддержку некоторых персональных компьютеров. Один из них - старый ноутбук Dell, который ранее имел Windows XP. Драйверы Windows XP WiFi работали, но Lubuntu не смог установить проприетарные драйверы. С тех пор WiFi больше не работает. После того, как я попытался переустановить драйверы bc43 для BCM4318, я получил несколько ошибок и до сих пор не могу связаться с сетью. Проводная сеть возможна и работает нормально
Начиная с устройств, которые, как я ожидаю, несовместимы с драйвером

Для конфигурации wpa_supplicant я скопировал конфигурацию по умолчанию и изменил сеть в соответствии с сетью.

Устройство видимо в / sys / class / net / wlan0, но оно никогда не отбрасывалось и не принималось.
