O cartão sem fio Lenovo ideapad 500-15acz não é reconhecido

Question

Instalei o ubuntu 15.10 no meu novo laptop que normalmente roda o Windows 10 e não consigo fazer o Ubuntu reconhecer que a placa wireless existe. O driver do Windows 10 é chamado Atheros WLAN Driver 7.35.295.2. Eu tentei algumas coisas em vários blogs, mas não consigo fazer nada funcionar.

lspci | grep -i wireless

não retorna nada.

Não tenho certeza do que tentar. Eu sei que a placa wireless funciona porque funciona na partição do windows. Alguma ajuda por favor?

    

Answer 1

Parece que este adaptador Broadcom Corporation Device [14e4:43ae] (rev 02) ainda não é suportado pelos drivers proprietários Linux ou Broadcom.
