Я пытаюсь настроить мой Raspberry Pi на использование беспроводной карты Realtek 8192eu, но без особой удачи. Я собрал hostapd и драйвер 8192eu. Мост устанавливается с помощью /etc /network /interfaces; точка доступа создана, и клиенты могут успешно связаться. Но они добровольно разъединяются через несколько минут и никогда не получают IP-адрес. Я думаю, что это означает, что запросы DHCP не передаются через мост.

В отчаянии я даже пытался установить dnsmasq и настроить его для выдачи адресов на wlan0, но безуспешно.
Изменить: Позже, я попытался включить беспорядочный режим на Wlan0:

Как вы можете видеть, по карте проходит трафик, но, похоже, это не решает проблему. Возможно, мост тоже нужен для распутства?
На стороне AP вот вывод dmesg:

Это определенно выглядит как успешная попытка ассоциации.

Опять же, это выглядит как успешное событие ассоциации, за которым клиент выбирает отключение. Зачем это делать? Возможно, потому что он не получает аренду DHCP вовремя?
