Не та модель, но проблема очень схожа. У меня на dell vostro 1000 (bcm4312) та же проблема.

На 4.1 работал wifi через ndiswrapper. После обновления - отказался. Модуль ядра установлен. ndiswrapper удалил и занес в блеклист, но при загрузке все равно пытается грузиться. Ин-фейс поднимается через раз. Работает с модулем wl. По команде modprobe wl и rmmod wl соответственно загорается и тухнет индикатор. Сети видит, но подключится - никак.
