Беспроводная проблема Ubuntu 13.10\14.04\14.10
У меня есть проблемы с беспроводной связью в Ubuntu 13.10\14.04\14.10, иногда когда я запускаю свой ноутбук, я не могу найти свой WiFi и после того, как я перезапускаю его, работает просто великолепно, но после того, как когда-то это отбрасывает соединение автоматически, и Wi-Fi исчезают снова. что я могу сделать?!! я использую lenovo z580.

Это могла бы быть проблема с отключенным питанием менеджер, поэтому попробуйте ниже команды и проверки,
sudo iwconfig wlan0 power off
Раз так попытка с отключением отладочной программы при помощи следующего,
modprobe -r iwlwifi && modprobe iwlwifi 11n_disable=1
