이전에도 몇 번 이 질문을 했지만 안타깝게도 답변을 찾을 수 없었습니다.
Ubuntu 14.04를 사용하여 여러 번 인터넷 문제를 해결하려고 시도했지만 내 시스템에 특정한 문제를 해결해야 할 것 같습니다.
한동안은 빠르게 가고, 그 다음에는 정말 느리게 가다가 한동안은 돌아오지 않을 것이다.
나는 HP 노트북을 가지고 있습니다:
lshw를 실행할 때 나타나는 내용은 다음과 같습니다. 코드:

답변1
라우터에 논스톱(1초마다 또는 더 빠른 속도)으로 핑을 시도하고 지연(지연)이 발생하는지 확인하세요.
라우터는 항상 2~3ms 이내에 신속하게 응답해야 합니다. 모든 인터넷 트래픽이 느려지는 동시에 속도가 느려지면 무선 문제(수신) 또는 라우터 문제(너무 많은 p2p 트래픽으로 인해 정체가 발생할 수 있음)를 의미한다고 말하고 싶습니다.
그리고 라우터 핑이 결코 느려지지 않는다면(항상 2-3ms) 지연은 라우터를 넘어서는 것입니다.
다른 아이디어:
- 다른 Wi-Fi 어댑터를 사용해 보세요.
- 다른 라우터를 사용해 보시겠습니까?
- 네트워크/광섬유 케이블을 구입하고 설치하시겠습니까?
- 더 빠른 인터넷 접속을 구매하시겠습니까?
버그일 수도 있습니다.http://www.ubuntu.com/usn/usn-2447-2/"USN-2447-1은 Linux 커널의 취약점을 수정했습니다. 관련 없는 회귀로 인해 업그레이드 후 여러 드라이버에 대한 TCP 처리량이 0으로 떨어집니다."
