Eu estava pesquisando na internet, mas não encontrei nenhuma resposta. Eu tenho ar mabook com cartão wifi BCM4321.
02:00.0 Network controller [0280]: Broadcom Corporation BCM4321 802.11a/b/g/n [14e4:4328] (rev 05)
Primeiro de tudo, eu tentei isso sem sucesso:
link
Eu coloquei na lista negra todos os outros drivers e ativei o driver wl. Então eu era capaz de conectar e usar o wifi. Mas só às vezes. Por enquanto estou conectado na internet pelo dongle wifi tp-link.
dmesg quando o wifi não funciona:
