Wi-Fi пропадает и повторно подключается к UBUNTU 14.04 (Realtek RTL8188)

Question 1

Я только что установил UBUNTU 14.04 LTS на Toshiba Satellite C655D. Мой Wi-Fi иногда отключается, и все, что мне нужно сделать для повторного подключения, - это отключить мой Wi-Fi и включить Wi-Fi с помощью значка беспроводной сети в правом верхнем углу. Это просто раздражает.

Любая помощь будет принята с благодарностью, я новичок в UBUNTU, но заинтересован в изучении команд Linux. К счастью, некоторые команды похожи на DOS и пакетный код.

Я использую роутер, и на данный момент у меня нет проблем с другими беспроводными устройствами, в том числе с другим портативным компьютером, работающим под управлением 14.04, но это более старый Aspire One.

Вот информация из сценария wireless_script, который я нашел на форуме:

Question 2

Сначала в Вашем изменении маршрутизатора 802.11bgn к 802.11bg.

Второе изменение wep шифрование только к wpa2 (CCMP) (AES) не (TKIP), если у Вас есть та опция, она будет работать лучше всего.

Треть установила Ваш беспроводной канал в маршрутизаторе к 1, или 11 затем сохраняют конфигурацию маршрутизатора и перезагружают его.

Четвертое движение в администратора сети в правом верхнем углу экрана и нажимает на соединения редактирования> беспроводная вкладка и установило IPv6 для игнорирования.

Теперь открываются, терминальные CTRL+ALT + _ T затем копируют и вставляют следующий код одна строка за один раз для точности:

echo "options rtl8192ce swenc=1 ips=0" | sudo tee /etc/modprobe.d/rtl8192ce.conf
sudo modprobe -rfv rtl8192ce
sudo modprobe -v rtl8192ce

Question 3

Question 4

У меня была та же проблема - я был ленив, таким образом, я сделал только № 4

, "входят в администратора сети в правом верхнем углу экрана и нажимают на соединения редактирования> беспроводная вкладка и устанавливают IPv6 для игнорирования"

..., и это работало! Спасибо
