Ubuntu/Mint(신뢰할 수 있음): Wi-Fi가 계속 종료됩니다.

데스크탑에서 Mint를 실행하고 있는데 매우 짜증나는 문제에 직면했습니다. Wi-Fi가 몇 분 또는 몇 시간 후에 계속 종료되고 자동으로 다시 연결되지 않습니다.

네트워크를 복원하려면 다음을 수동으로 실행해야 합니다.

sudo service network-manager restart

문제없이 다른 여러 장치를 연결했습니다.

무슨 일이 있었는지 알려주세요. 이것은 몇 달 동안 나를 미치게 만들었습니다.

편집: 지난 주에 새 노트북을 구입했는데(민트 17도 있음) 이제 새 컴퓨터에서도 똑같은 문제가 발생합니다. 글쎄, 내가 운이 좋지 않거나 민트(또는 우분투)에 심각한 네트워크 버그가 있습니다.

답변1

이전에 데비안에서도 비슷한 문제가 발생했습니다. 나는 그것을 시도하고 고치는 몇 가지 방법을 찾았습니다. 첫 번째는 모든 이더넷 연결을 비활성화하고 시작 스크립트가 이더넷 연결을 시작하지 않도록 하는 것입니다. 그런 다음 시작 시 WiFi를 설정하여 WiFi 엔드포인트에 자동으로 연결하세요. 시작 스크립트에서 이것을 시도해 볼 수 있습니다: service network-manager restart ifconfig eth0 down ifconfig wlan0 up

또 다른 옵션은 dchp가 상자에서 IP를 요청하도록 하는 것입니다. 연결이 확실하다는 것을 알았습니다. udhcpc -i device_name그러나 이로 인해 정적 경로가 유지되지 않는 등 이상한 동작이 발생할 수 있습니다. 나는 때때로 내 상자가 고정 경로에 있음에도 불구하고 IP 주소를 변경하는 것을 발견했습니다.

문제는 상자에 있는 WiFi 모듈과 엔드포인트(라우터) 사이의 호환성 문제일 수도 있고, 엔드포인트의 보안이 어떤 이유로 특정 연결을 자동으로 끊는 것일 수도 있습니다. 즉, 특정 요청이나 동작이 이를 트리거할 수 있습니다.

답변2

나는 같은 문제에 직면했다. 제가 드릴 수 있는 최선의 대답은 이더넷 케이블을 구입하여 액세스 포인트에 직접 연결하는 것입니다. 그러나 이것은 단지 해결 방법일 뿐입니다. 이는 Ubuntu 버그일 수 있습니다. Ubuntu를 최신 14.04로 업데이트한 후 문제가 사라진 것 같습니다.
