Мда. И как ты предлагаешь это читать?
Смореть как.
Или сюда.
Тогда люди потянутся.

Ну из этой каши видно что контролер у тебя такой:
07:00.0 Network controller: Broadcom Corporation BCM43142 802.11b/g/n (rev 01)
Тебе нужно firmware от этого чипсета.
В сети инфы как грязи. Конкретно твой случай.

После
sudo apt-get install firmware-brcm80211
перезагрузись.
