wi-fi не работает без подключения провода Ethernet

[Pe4eneg]

Здравствуйте, уважаемые! Проблема такова: система Debian10 (Linux homeserver 4.19.0-13-amd64 #1 SMP Debian 4.19.160-2 (2020-11-28) x86_64 GNU/Linux), есть сетевая карта и  usb-свисток TP-link TL-WDN3200. Все драйвера и прошивки, включая non-free установлены. Оборудование системой определяется, ip (разные, естественно) снаружи пингуются. Но, при отключении кабеля падает и wifi соединение.

Третий день копаю гугл, никак не могу найти правильный ответ. Уже думаю бросить это занятие, но хочу принципиально понять суть проблемы. К сожалению, своих знаний не хватает, нужны подсказки.

Cообщение объединено 29 Декабря 2020, 18:26:43Вопрос закрыт. Проблема решена путем скачивания всех недостающих драйверов и подсовывания их на этапе начальной настройки при переустановке системы. Извините за беспокойство.
ЗЫ Как же все сложно-то с линуксом...

Я уж читать, вникать начал было, пока не прочел концовку.
Хорошо, что заработало.
