Asus ROG G751JM - Беспроводная сеть является очень медленной в Ubuntu 14.10

У меня есть двойная загруженная конфигурация с Windows 8.1 по умолчанию и последней 64-разрядной Ubuntu 14.10.

Беспроводная сеть является очень медленной. В Windows 8.1 это работает как очарование, в то время как на Ubuntu, я становлюсь почти 1/8-м из исходной скорости.

Однако, когда я использую Ethernet, я получаю полную скорость загрузки/загрузки, которую я, как предполагается, имею, точно так же, как Windows.

Когда я переключаюсь от Ethernet до беспроводной связи, все веб-сайты внезапно прекращают загружаться, и apt-get берет навсегда в запуске загрузки.

После этого сценария вот вывод:

Я следовал, почти каждое решение, упомянутое здесь на, Спрашивают Ubuntu и другие веб-сайты, но ни один из них, кажется, не работает.

Поддержка Asus подвела меня. Когда я связался с ними:

Для Вашего случая, который может быть вызван отсутствием драйвера с ним. (драйвер не совместим с Linux Ubuntu),

Для Вашей информации, согласно сайту поддержки: http://support.asus.com.cn/download.aspx?SLanguage=en&p=3&m=G751JM&hashedid=H1PGPvZ0ODsnDxTf

Существует только win8.1 драйвер версии для ноутбука G751JM

Мы не рекомендуем пользователю использовать Linux Ubuntu ОС с продуктом G751JM.

Мы передали Вашу почту технологической команде R&D, позвольте им проверить и рассмотреть для создания ее в будущем.

Извините за доставленные неудобства. Большое спасибо за Ваше понимание

Спасибо за Вашу поддержку продукт Asus. Желание у Вас есть хороший день.

Как у меня может быть хороший день, зная, что ноутбук, который я купил у своих собственных сбережений, не совместим с моей наиболее используемой ОС?

Я буду действительно ценить его, если кто-то мог бы указать на меня на другое решение для этой проблемы. Действительно ли покупка является внешней картой беспроводной сети, единственное возможное решение?
