問題描述

我有一個 Quectel EG25-G 設置，但每當我連接時（重新啟動后），它會連接 20 秒然后斷開連接。 它發生在

Jun 24 04:59:32 linux NetworkManager[5093]: <info> [1656046772.4569] device (ttyUSB2): state change: activated -> failed (reason 'modem-no-carrier', sys-iface-state: 'managed')
Jun 24 04:59:32 linux NetworkManager[5093]: <warn> [1656046772.4677] device (ttyUSB2): Activation: failed for connection 'telstra'

點，但我不明白為什么會這樣。

有人可以指出我正確的方向嗎？

配置：

nvidia@localhost:~$ sudo cat /etc/NetworkManager/system-connections/telstra
[sudo] password for nvidia:
[connection]

看到我無法刪除它，我找到了答案：

這里有人建議更新到最新的ModemManager，例如：代碼：

sudo apt-get install software-properties-common # contains add-apt-repository
sudo add-apt-repository ppa:aleksander-m/modemmanager-bionic
sudo apt-get update
sudo apt-get install modemmanager libqmi-utils libmbim-utils policykit-1
sudo reboot

一切都開始起作用了。 一定是 NVidia 的基本映像附帶的舊版 ModemManager 中的一個 ModemHandler 錯誤。
