무선 연결되었지만 인터넷에 액세스 할 수 없음


18

나는 우분투 15.04를 생생하게 사용하고 있으며 Wi-Fi에 연결되어 있지만 Firefox를 열 때 "서버를 찾을 수 없습니다"라고 말하고 소프트웨어 업데이터를 엽니 다. 다운로드하지 못했습니다. 기본적으로 인터넷에 액세스 할 수 없습니다. 그러나 이전에는 우분투 14를 사용했으며 오류없이 정상적으로 Wi-Fi를 사용할 수 있습니다. 또한 내 Windows와 전화도 오류없이 작동합니다. 여러 번 다시 설치를 청소했는데 같은 문제가 있습니다.

내 상황에 대한 정보는 다음과 같습니다.

내 와이파이 장치는 : Huawei HG8045A

글쎄, 우분투 포럼 에서 물어 보니 매우 빨리 대답했고 효과가있었습니다.

Click on Network Manager> 
Click 'Edit' 
Edit the wireless connection>
Click the IPv6 tab>
Set IPv6 to ignore>
click OK>
Reboot.

매력처럼 일했다!

답변 해주셔서 감사합니다. 우분투 15.10 OS에서 작동합니다.

이 방법은 작동하지만 때로는 Wi-Fi가 여전히 떨어지거나 연결되었지만 작동하지 않습니다. 나는 truongnm 상태를 수행하는 것 외에 모뎀 라우터에 따라 모뎀 라우터 설정에서 ipv6을 비활성화 할 수 있다는 것을 알았습니다.

당신이 안드로이드 전화를 가지고 있다면 당신은 또한 Wi-Fi 어댑터로 사용할 수 있습니다 ... 나는 이것을 몇 번해야했고 그것은 잘 작동합니다.

  • 휴대 전화에서 모바일 데이터를 끕니다.
  • USB 테 더링을 켭니다 (휴대 전화의 Wi-Fi가 꺼질 때 개인 핫스팟 만 켜지 마십시오).
  • 휴대 전화와 PC를 연결해야합니다.

이것은 문제를 해결하는 좋은 예이지만 문제는 아닙니다. 바라건대 이것이 실제로 무엇이 잘못되었는지 알 때까지는 일시적인 해결책 일 것입니다.
