Проблема с подключением к Интернету с беспроводной картой rtl8192ce / toshiba satellite / realtek

** Обновление - я попытался отключить функцию энергосбережения микропрограмм беспроводной карты, и теперь я остаюсь на связи, когда нахожусь примерно в 15 футах от маршрутизатора. До перехода на Ubuntu у меня было надежное соединение как минимум вдвое дальше, и все мои другие Wi-Fi-устройства все еще подключались на расстоянии более 30 футов. До отключения функции энергосбережения прошивки я не мог оставаться на связи в непосредственной близости от маршрутизатора. Поскольку это, кажется, помогло, я собираюсь найти инструкции, которые я видел, о том, как отключить другую функцию энергосбережения для беспроводной карты.Я опубликую как команду, которую я уже использовал, так и другую команду, как только найду их снова - они обе были в одном сообщении.

** обновление: я выполнил следующие команды:

sudo modprobe -v rtl8192ce ips=0 fwlps=0

.... но они, похоже, не получают надежного сигнала с расстояния более 15 футов от маршрутизатора. Опять же, множество других устройств Wi-Fi получают сигнал на расстоянии более 30 футов, и этот компьютер делал то же самое до Ubuntu. Мне нужно будет придерживаться этого, пока я не найду исправление, потому что я не могу использовать свой ноутбук только в комнате с маршрутизатором. :)

Я менее 24 часов в Linux / Ubuntu. Я на 12.04 LTS. (когда это было впервые опубликовано)

Сначала я могу нормально подключиться к Интернету. Но примерно через 2–20 минут я больше не могу просматривать новые веб-страницы, хотя, похоже, я все еще подключен к маршрутизатору. Отключение и повторное подключение исправляет каждый раз.

Я запустил несколько вещей, которые, вероятно, будут заданы мне после просмотра других похожих постов. Пожалуйста, дайте мне знать, если вам что-нибудь понадобится.

Этот запуск nm-tool (см. Выше) был сделан, когда у меня не было доступного интернет-соединения, хотя, похоже, я каким-то образом подключен к маршрутизатору.

Любая помощь будет принята с благодарностью !!!

Кроме того, хотя у меня возникли некоторые трудности с установкой 12.04 (были проблемы с файлами grub / boot), я готов перейти на 13, если это решит эту проблему.Что касается поддержки в течение 13 и 9 месяцев - означает ли это, что мне придется установить новую версию Ubuntu через 9 месяцев, чтобы продолжать получать обновления безопасности / другие обновления? Или 13 тогда просто станут новым LTS? Я знаю, что это очень простой вопрос, но, эй, я новичок в Linux!
