나는 새로운 Dell Latitude e7440과 Dell Wireless 5570 HSPA+ 모바일 광대역 카드를 가지고 있습니다. 광대역 카드를 사용할 수 없습니다.
카드를 볼 수 있습니다:

하지만 난 못해사용어떤 식으로든 카드.
- AT 명령어를 입력할 수 있는 곳이 없습니다
/dev/ttyUSBx. - Network Manager에 모바일 광대역 연결이 표시되지 않습니다.
mbim-network단순히 모뎀 연결이 실패했다고 말하는 것과 같은 도구
내 Dell BIOS 버전은 A10다음과 같습니다. BIOS에서 카드를 볼 수 있습니다. 활성화되어 있으며 이 관점에서는 아무런 문제가 없어야 합니다. 드라이버를 디버깅해야 한다면 시도해 볼 의향이 있지만 어디서부터 시작해야 할지에 대한 지침이 필요합니다. 어떤 도움이라도 대단히 감사하겠습니다.
다음은 디버그 출력 목록입니다. 도움이 되셨다면 댓글로 더 많은 정보를 요청해주세요.

답변1
5570(지금도 갖고 있음)과 같은 Dell 브랜드 Sierra 무선 모뎀은 저전력 모드에서 복구하려면 마법의 "DMS Set FCC Auth" 명령이 필요합니다. 자세한 설명은 다음과 같습니다.https://sigquit.wordpress.com/2015/02/09/dell-branded-sierra-wireless-3g4g-modem-not-online/
ModemManager를 사용하는 경우 libqmigit에서 ModemManager를 컴파일하여 이 문제를 해결할 수 있습니다.
답변2
옵션에 APN이 없습니다 --wds-start-network. CDMA/EVDO 네트워크에 있는 경우에는 필요하지 않지만 GSM/UMTS/LTE에서는 (보통) 명시적인 것이 필요합니다.
dhclientQMI WDS 시작 네트워크가 오류 없이 반환되면 WWAN 인터페이스에서 실행해 보십시오.
