Ubuntu22.04LTS/高通X55 5G / NetworkManager配置
提问于 2022-05-11 12:32:38
我有问题，让网络管理在Ubuntu22.04LTS，以正确打开星上高通Snap巨龙X55 5G调制解调器。如果我尝试，似乎NM试图配置连接，但从不打开所需的硬件。
如果我做了一个
$> sudo qmicli -p -d /dev/wwan0mbim0 --device-open-auto --dms-foxconn-set-fcc-authentication=0然后启用
$> sudo mmcli -m 0 --enable我能打开调制解调器。如果我接着输入APN数据，我就可以在8.8.8.8下切换Google服务器。
然后我尝试设置DNS：
$> nmcli connection modify Oister\ Bredbaand ipv4.dns "8.8.8.8,8.8.4.4" 然而，我无法对任何事情进行实际的主机查找--我认为我敢于用手打开调制解调器的事实使整个系统非常不安。
在对此进行了更多的修改之后，我删除了上面的手动DNS配置，并设置了
$> sudo nmcli connection modify Oister\ Bredbaand ipv4.method "auto"和
$> sudo nmcli connection modify Oister\ Bredbaand ipv6.method "DHCP"我现在有了移动互联网！
但是，我仍然必须启动连接--当图标试图在尚未启动的硬件上配置连接时，在顶部栏中看到图标闪烁--然后按qmcli手动启动它。
这闻起来像是网络管理器的漏洞。

事实证明，在Ubuntu中，FCC设备不再自动打开--除非您再次引入所需的快捷方式。
sudo ln -sft /etc/ModemManager/fcc-unlock.d /usr/share/ModemManager/fcc-unlock.available.d/*鲍勃是你叔叔。设备的固件仍然存在一些与设备启动无关的错误。
