Apple macbook air, модель 1.1 - Lubuntu 14.04, 64-разрядная версия - Wi-Fi Broadcom BCM4321 не работает

Я искал в Интернете, но не нашел ответа. У меня есть mabook air с картой Wi-Fi BCM4321.

02:00.0 Network controller [0280]: Broadcom Corporation BCM4321 802.11a/b/g/n [14e4:4328] (rev 05)

Прежде всего, я безуспешно попробовал: https://help.ubuntu.com/community/MacBookAir1-1/Raring#Wireless

I занес в черный список все остальные драйверы и активировал драйвер wl. Затем я смог подключиться и использовать Wi-Fi. Но только иногда. На данный момент я подключаюсь к Интернету с помощью ключа Wi-Fi tp-link.

dmesg, когда Wi-Fi не работает:
