Wi-Fi не работает в Ubuntu 14.04 после короткого времени, пока я не перезапускаю систему
Моя ситуация:
Я установил Ubuntu 14.04 LTS на моем новом ноутбуке HP.
Моя проблема:
Моя система может соединиться с моим маршрутизатором Wi-Fi после того, как система запускается, но после нескольких минут (30-45 минут) Интернет не работает даже при том, что шоу состояния Wi-Fi, как соединено. Я выполнил wireless_script, когда состояние Wi-Fi показывают, как соединено, но Интернет все еще не работает.

Первая попытка
$ echo "options rtl8723be fwlps=0 swlps=0" | sudo tee /etc/modprobe.d/rtl8723be.conf
Перезагрузка и если это все еще имеет проблемы, следуют инструкциям ниже для установки бэкпортов
$ sudo apt-get install build-essential linux-headers-generic
$ wget -N -t 5 -T 10 https://www.kernel.org/pub/linux/kernel/projects/backports/stable/v3.19-rc1/backports-3.19-rc1-1.tar.gz
$ tar -xf backports-3.19-rc1-1.tar.xz
$ cd ~/backports-3.19-rc1-1
$ make defconfig-rtlwifi
$ make
$ sudo make install
, Перезагружают систему.
Примечание
единственная проблема с бэкпортами - то, что они должны быть созданы для любого нового ядра, которое установлено с обновлениями, когда это происходит Вы
$ cd ~/backports-3.19-rc1-1
$ make clean
$ make defconfig-rtlwifi
$ make
$ sudo make install
, можно также хотеть проверить настройки шифрования маршрутизатора Wi-Fi, чтобы видеть, ли они WPA2-AES или WPA2 только, как это было бы предпочтено.
Редактирование (Поддержка другого драйвера ядра беспроводной связи)
В вышеупомянутом, мы добавляем поддержку бэкпорта rtlwifi драйвер, какую Беспроводную связь/Сетевую плату ноутбука HP имеют. Другой производитель ноутбуков обеспечивает другую карту поставщика Wirless, таким образом, для того сначала необходимо найти название драйвера ядра беспроводной поддержкой карты, можно получить это просто выполненным lspci команда в оболочке, перейдите в Network Controller и посмотрите последнюю строку его.
