Ubuntu 14.04를 사용하고 있으며 rtl8723be 드라이버를 설치했고 WiFi는 몇 달 동안 잘 작동했지만 잠시 후 응답을 멈췄습니다 (5 분 정도).
이 링크 의 첫 번째 해결책을 따라 문제를 해결했습니다. 시스템을 재부팅했을 때 네트워크 설정에서 "무선 연결"옵션이 사라졌습니다. 이 링크 에서 첫 번째 솔루션을 시도했지만 둘 다 도움이되지 않았습니다.
이것은 유용 할 수 있습니다.

미리 감사드립니다.
우선 지원되지 않는 커널 4.1.0-rc7 +가 있습니다.
먼저 다음을 실행하여 드라이버를 제거하는 것이 좋습니다.
sudo apt-get remove rtlwifi-new-dkms rtl8723au-bt-dkms
그런 다음 다음을 실행하여 지원되는 커널 4.2를 설치하십시오.
sudo apt-get install linux-generic-lts-wily
아마도 Wi-Fi는 재부팅 후 정상적으로 작동합니다. 그렇지 않은 경우 rtlwifi-new-dkms.
