Чипсет Broadcomm 4356 WI-FI, не требуемый у Бионического Бобра

Я использовал Ubuntu на ThinkPad некоторое время, и при обновлении ядер у Бионического Бобра драйверы, кажется, не работают больше: Я попробовал каждый доступные драйверы (br-4, brcm-brfmac, заголовки Linux и т.д....), и я не могу найти проблему. Я не технический гений, но я следовал за каждой деталью (за исключением карты, которая не зарегистрирована) решить эту проблему, детализированную здесь...

До сих пор я попробовал следующие ядра: b43, brcmfac, bcmwl-kernel-source.

Сообщите мне, есть ли у Вас какая-либо идея о том, как диагностировать проблему или восстановить ее?
