대부분의 경우 내 무선 네트워크는 완벽하게 작동합니다. 그런데 하루에 한 번 정도 무작위로 연결이 끊어지고 무선 키링 인증이 팝업됩니다. 키링에 올바른 정보를 모두 입력했는데 연결을 누르면 네트워크 재연결에 실패하고 인증창이 다시 뜹니다. 네트워크는 제대로 작동하고 있으며 이것이 영향을 받은 유일한 컴퓨터입니다. 컴퓨터를 다시 시작하면 이 문제가 해결되지만 프로덕션 시스템이므로 작업 중인 작업을 중지하고 다시 시작해야 한다는 점은 상당히 답답합니다.
나타나는 화면은 다음과 같습니다.
무선 카드는 D-link Xtreme N DWA-552입니다.

업데이트: VLC로 인해 이 문제가 더 자주 발생하는 것 같습니다. 정상적인 조건에서는 하루에 한 번만 발생했지만 어제 VLC를 실행했을 때 훨씬 짧은 기간에 여러 번 충돌이 발생했습니다. 이것이 관련이 있는지 확실하지 않지만 꽤 이상합니다 ...

내 MacBook 2,1에서도 이 문제가 발생합니다. 이에 대해 할 수 있는 일은 많지 않지만 모듈을 재설정하면 적어도 다시 작동할 수 있습니다.
sudo sh -c 'rmmod ath9k; restart network-manager; modprobe ath9k'
