Беспроводная связь не работает в Vostro 1500

У меня ноутбук Vostro 1500, я установил Ubuntu. Но беспроводная связь не работает и у меня нет доступа в интернет.

Я вошел в терминал и набрал lspci.

Как это исправить?

Если это Ubuntu 14.04 или 14.10 sudo apt-get purge bcmwl-kernel-source broadcom-sta-* sudo apt-get update && sudo apt-get install firmware-b43-installerи перезагрузите

Если у вас нет интернета, скачайтеhttps://www.dropbox.com/sh/wal711rod6rssea/AAAMtlvWNyq-5BBquyEE6vW2a?dl=0 и скопируйте его на DVD/CD/USB-накопитель и скопируйте его в папку Downloads Ubuntu install. Щелкните правой кнопкой мыши по файлу в Ubuntu и выберите "Извлечь здесь". Затем вы сможете

sudo mkdir /lib/firmware/b43

sudo cp ~/Downloads/b43/* /lib/firmware/b43/
