Wi-Fi это не линуксовое. Но может быть можно что-то сделать?

Recommended Posts

Hi all.

Имею шляпу с wi-fiем под kubuntu. По умолчанию ставит драйвер "rt73usb" , однако он ужасно работает. Уровень сигнала не доходит выше 40% даже, если сидеть в упор с вещалкой. Скорость оставляет желать лучшего, а время отклика, как будто я ору в африку. Использую шифрование WPA. Под окнами всё, как влитое, но это не выход из ситуации. Итак, информация:

Ноут - MSI S262;

Wi-Fi карточка - неизвестно. (Тут информации я не нашёл. Документов к ноуту нету, а гугл твердит всегда по-разному.)

Драйвер - rt73usb. (Тут сразу мне кажется, что драйвер явно не от него, т.к. "usb", а карточка интегрированная.)

Команды в терминале ввести смогу, но не знаю какие.

Буду рад и благодарен помощи с вашей стороны.

вот так... wi-fi (карточка) работает.

На шине pci его нет. Видно, и вправду на usb повесили.

Moжете это проверить через lsusb.

Ещё можете попробовать сконфирурировать сеть без шифрования командой iwconfig и поднять командой ifconfig. Если ситуация не улучшится, то только ядро обновлять, надеясь, что подправили драйвер.
