나는 몇 주 동안 Kubuntu 22.10을 시험해보고 있습니다. 이전에는 잘 작동했지만 어제부터 네트워크 연결에 다운로드 또는 업로드 속도가 없습니다. 동일한 장치의 Ubuntu 시스템이 완벽하게 작동하므로 하드웨어나 라우터 문제를 배제했습니다.(이중 부팅 설정이 있습니다) 나는 포럼을 살펴보았지만 나에게 도움이 되는 것을 찾지 못했습니다. 방화벽을 비활성화해 보았지만 역시 효과가 없었습니다. 라우터 관리자 페이지에는 연결할 수 있지만 다른 페이지에는 연결할 수 없습니다.
도움이 될지는 모르겠지만 결과는 다음과 같습니다.lshw -c Network
