ifup не может вызвать интерфейс через раз

Я получаю странную проблему, когда ifup терпит неудачу при каждом другом запуске. Вот вывод, который вы видите в виде сбоя, успеха, сбоя и т. Д.:

edit : Нашел верхний фиксатор температуры, если я наберу sudo ifdown wlp3s0 перед каждым sudo ifdown wlp3s0 && sudo ifup -v wlp3s0, он будет запускаться каждый раз, но я до сих пор не знаю, что, черт возьми, происходит ??
