Atheros QCA9565 / AR9565 ведет себя странно (ахт9к связано?)

Мой Qualcomm Atheros QCA9565 / AR9565 начал странно себя вести. Он не имеет никакого сигнала и иногда не находит точки доступа или не находит, но не может подключиться.

Я читал, что компиляция backport, возможно, решит проблему, но безуспешно. Я пытаюсь установить backport (4.4.2-1, если быть точным), но я получаю эту ошибку при запуске makeкоманды:
