Wi-Fi, не работающий с BCM43602 на Ubuntu 18.04

Я попробовал все от этой учебной Установки Драйверы беспроводных устройств Broadcom без любого успеха. bcmwl-kernel-source просто оставляет мой адаптер Wi-Fi необнаруженным и firmware-b43-installer заставляет адаптер видеть беспроводные сети, но он не может соединиться ни с одним из них. Я попробовал, возможно, каждый совет, который я мог найти на Google.Это не работает.

Когда я загрузился от liveusb, прежде чем я установил 18.04 были подобные проблемы с Wi-Fi - он работал только в 2 в 3 попытках, и я должен был перезагрузить снова, чтобы он соединился. После того, как я установил 18,04 Wi-Fi, работавшего в течение 6 часов, затем я приостановил свой ПК и затем никакой Wi-Fi и никакую надежду …
