беспроводная сеть

Когда я подключаю свой ноутбук к защищенному маршрутизатору wpa2 , используя wicd, у меня нет проблем с подключением.

НО, когда я соединяюсь со следующей командой командной строки (как описано здесь )

ОБНОВЛЕНО:

ifconfig wlan0 up wpa_supplicant -B -Dwext -i wlan0 -c /etc/wpa_supplicant.conf dhcpd wlan0 

Моя связь нестабильна, иногда иногда работает, указывается следующим выходом:

Мне кажется, что беспроводной сигнал низкий, но это не объясняет, почему работает wicd.

вам нужно sleep 10s прежде чем часть dhcpd по крайней мере
