Ноутбук не видет беспроводные сети

[Lain]

После установки ubuntu на ноутбуке, компьютер сам сходу видел кучу доступных wifi сетей и всё работало. Но потом почему-то перестало. Пыталась настроить wifi вручную как написано здесь. Но команда iwconfig выдаёт мне только 2 устройства: lo и eth0. Больше ничего. Как это понимать? Помогите пожалуйста разобраться.
P.S. Перекопала уже большое количество документации по вопросу настройки wifi, но ничего подобного не нашла(

[Stay_Strong]

перестало после чего? после какого действия?

[Lain]

В том-то и дело, что не знаю(

[Kozak]

сначала

Код: [Выделить]

sudo ifconfig wlan0 up
если не поможет - вывод команд

Код: [Выделить]

lspci
ifconfig -a

[Alie Alexandross]

kozak, iwconfig выводит все интерфейсы, не только активные. ifconfig -a покажет те-же lo и eth0...

Если предположить что это:

действительно card reader (судя по драйверу rts_pstor), то в lspci нет информации о wireless карте. Покажите вывод

Собсно, вот ваша карта. Для работы ей нужен драйвер b43 или wl.
Первый собирается из пакета bw43-fwcutter. »ТУТ« есть инструкция по установке b43.
Второй описан в DebianWiki: »wl«.
Попробуйте сначала wl, если не поможет - переходите к b43.

[Lain]

C wl ничего не вышло(не могу вообще разобраться в инструкции).
Пробовала установить b43. Вроде бы всё делаю правильно, но драйвер не устанавливается и всё(

Пробовала ещё установить, как написано здесь, но на шаге
