Обход 'Трудно заблокированный' Wi-Fi
Привет!
Таким образом, я недавно установил помощника Ubuntu 14.04, но драйверы Wi-Fi повредились после установки. Теперь Wi-Fi является твердым блоком, и я не могу повторно активировать его. У меня нет кнопки Wi-Fi, ни установки в BIOS. Даже USB не работает. Какие-либо идеи о том, как я могу зафиксировать Wi-Fi?
Извините за не предоставление достаточной информации о проблеме. Я не действительно знаком со сценарием Wi-Fi, который Вы связали, но большой инструмент, спасибо за совместное использование :-)
Вот вывод из сценария Wi-Fi:

Согласно сообщения форума можно попытаться повторно вставить модуль для беспроводной карты
sudo rmmod -v ipw2200 && sleep2 && sudo modprobe ipw2200
кроме того, удалить строку && /sbin/modprobe -r mac80211 от /etc/modprobe.d/iwlwifi.conf файл
