私は新しいDell Latitude e7440とDell Wireless 5570 HSPA+モバイルブロードバンドカードを持っています。ブロードバンドカードは使用できません。
カードを見ることができます：

しかし、私はできません。使用何らかの方法でカード。
- AT命令を入力できる場所はありません
/dev/ttyUSBx。 - Network Managerにモバイルブロードバンド接続は表示されません。
mbim-network単にモデム接続が失敗したと言うようなツール
私のDell BIOSバージョンはA10次のとおりです。 BIOSでカードを見ることができます。有効になっており、この観点からは問題がないはずです。ドライバをデバッグする必要がある場合は、試してみたいと思いますが、どこから始めるべきかについての指示が必要です。どんな助けでも大変感謝します。
以下はデバッグ出力のリストです。参考になった場合は、コメントでより多くの情報をリクエストしてください。

答え1
5570（今も持っている）のようなDellブランドのSierraワイヤレスモデムは、低電力モードから回復するために魔法の「DMS Set FCC Auth」コマンドが必要です。詳細な説明は次のとおりです。https://sigquit.wordpress.com/2015/02/09/dell-branded-sierra-wireless-3g4g-modem-not-online/
ModemManagerを使用している場合は、libqmigitでModemManagerをコンパイルすることでこの問題を解決できます。
答え2
オプションにAPNはありません--wds-start-network。 CDMA/EVDO ネットワークにある場合は必要ありませんが、GSM/UMTS/LTE では（通常）明示的なものが必要です。
dhclientQMI WDS起動ネットワークがエラーなしで返される場合は、WWANインターフェースで実行してみてください。
