며칠 동안 내 노트북에서는 연결 속도가 매우 느렸지만 다른 모든 장치(휴대폰, 태블릿, 아파트에 있는 다른 사람의 컴퓨터)에서는 연결이 매우 빠릅니다. 예를 들어 제 휴대폰에서는 Wi-Fi에서 62Mbps 속도 테스트에 도달했고 내 컴퓨터가 테스트를 시작도 못해요...
시간이 걸린다고 느끼는 것은 첫 번째 연결입니다. 예를 들어 비디오를 원활하게 재생할 수 있지만 비디오를 시작하는 데 40초가 걸릴 수 있습니다. Google에서 간단한 검색을 수행하는 것만으로도 시간이 초과되거나, 여러 번 새로 고쳐야 하거나, 완료하는 데 최대 40초가 걸릴 수 있습니다.
이더넷을 사용하더라도 다른 곳(직장)의 연결도 느린 것 같지만 약간 더 좋습니다.
ping make를 시작하는 데 20초에서 40초가 걸리더라도(이후에는 원활하게 작동합니다) ping의 연결을 보여주는 이 gif를 참조하세요.
때로는 Wi-Fi에 연결되어 있지도 않은데 연결 시간이 초과되어 핑이 제대로 작동할 수도 있습니다. 예를 들어 다양한 DNS 서버에 수동으로 연결을 시도했는데 때로는 연결이 작동하고 때로는 시간이 초과되었지만 ping이 동시에 작동할 수도 있습니다.
일반적으로 웹 사이트에 연결하려고 하면 curl첫 번째 시도 시간이 초과되고 10~40초 내에 웹 사이트에 연결되며 다음 시도는 거의 즉각적으로 이루어집니다.

또한 다른 시스템(xubuntu 20.04) 부팅을 시도했는데 비슷하게 느렸기 때문에 내 구성과 관련된 문제는 아닌 것 같습니다(NixOs Unstable을 실행 중입니다). 반면, 핫스팟으로 설정한 휴대폰에 연결하면 속도가 빨라서 하드웨어 문제는 아닌 것 같은데... 또 이더넷(직장에서)에서도 비슷한 속도로 인터넷이 느려진 경험이 있습니다. ).
또한 ping이 매우 느릴 때 많은 패킷을 삭제할 것으로 예상했지만 실제로는 어떤 패킷도 삭제하지 않습니다. 각 패킷은 상당히 빠르게(10ms로 보임) 획득되지만 전송하기 전에 5초 동안 기다립니다. 다음 패킷(1초 대신):
(이 예에서는 첫 번째 줄이 직접 나타나며(캐시될 수 있음) 때로는 나타나는 데 몇 초가 걸립니다.)
몇몇 사람들이 제게 대해 물어보 resolve.conf더군요. 그래서 제가 이더넷을 사용하는 동안 직장에서 가져온 것 하나를 보여드리겠습니다. ( 8.8.8.8속도를 향상시키기 위해 네트워크 관리자를 통해 DNS 서버로 추가했지만 나아지지는 않은 것 같습니다.) 그리고 오늘 나중에 보내세요. 집에 있을 때:

Wi-Fi 카드에서 정보를 얻을 수도 있는데, ethtool -i DEV_NAME제게는 도움이 되었습니다 ethtool -i wlan0. 또한 실행하여 man ethtool드라이버, 테스트 등과 같은 다른 모든 옵션을 볼 수도 있습니다. 기본적으로 아래의 모든 옵션을 선택/설정할 수 있습니다.고급 무선 옵션,그래서특성Windows를 사용하는 경우 Wi-Fi 카드를 확인하세요.
