답변1
이것이 왜 효과가 있었는지 완전히 확신할 수는 없지만 효과가 있었던 것 같습니다. 이상적인 솔루션은 아니지만 적어도 작동합니다.
내가 한 일은 라우터에 설정한 주소 예약을 제거하고 IPv4 Settings → Method"수동" 대신 "자동(DHCP)"으로 설정한 것입니다. (이전에 수동으로 설정하려고 시도했는데 "작동"했지만 실패했습니다. 내 문제를 해결하세요). 저도 IPv6 Settings → Method직감적으로 '무시'로 설정했습니다.
그 후 resolveconf및 network-manager서비스를 다시 시작했지만 도움이 되지 않는 것 같습니다. 그래서 서비스를 다시 시작하려고 시도했지만 networking실패했습니다. 조금 검색해 본 결과 네트워크 인터페이스를 다시 시작하는 방법이 지원되지 않는 것 같아서 대신 수동으로 다시 시작했습니다.
sudo ifdown --exclude=lo -a && sudo ifup --exclude=lo -a
그것은 트릭을 수행 한 것 같습니다. 고정 IP 할당이 그것과 관련이 있는지 또는 IPv6을 비활성화했는지는 확실하지 않지만 어느 쪽이든 지금은 작동합니다.

12.x에서 kubuntu 14.04로 업그레이드한 후에도 이와 동일한 간헐적인 네트워크 연결 문제가 발생했습니다. 직감으로 "ipv6 끄기" 페이지를 검색한 결과 askubuntu: ipv6 비활성화. 해당 sysctl 단계를 수행했는데 이제 문제가 해결된 것 같습니다. 싸게 사는 물건.
