무선 인터페이스가 작동을 멈추고 netcfg에서 네트워크를 찾을 수 없다고 보고합니다.

나는 종종 Arch Linux 설치에 문제가 발생합니다. 무선 네트워크는 몇 분 동안 작동한 후 무작위로 사라집니다. Wi-Fi 메뉴를 통해 다시 시작하려고 하면 네트워크가 없다는 메시지가 나타납니다.

 > sudo wifi-menu
:: Scanning for networks                                                [FAILED] 
 > No networks found

netcfg를 직접 실행하면 다음이 수신됩니다.

sudo netcfg wlan0-2WIRE555
:: wlan0-2WIRE555 up                  [ BUSY ] Successfully initialized wpa_supplicant
Could not set interface wlan0 flags (UP): Connection timed out

출력은 lspci다음과 같습니다

이런 일이 발생할 때마다 인터넷이 작동하려면 재부팅해야 합니다. 수동으로 다시 시작하는 데 사용할 수 있는 시스템 명령이 있습니까? 이것이 영구적으로 고칠 수 있는 문제인가요?
