我正在使用 Debian 系统：
# uname -a
Linux iot-gate-imx8 5.4.24-iot-gate-imx8-2.0 #1 SMP PREEMPT Thu Sep 3 10:30:00 IDT 2020 aarch64 GNU/Linux
我有一个MODEM连接（处于活动状态且正在工作）：
# nmcli con
NAME UUID TYPE DEVICE
MODEM 425b609c-c893-4178-b3c3-88a8f2124b33 gsm ttyUSB2
Wired connection 1 679f5ed8-61f1-3cc4-bb4f-376b4e841276 ethernet --
Wired connection 2 417df684-700b-337c-8737-9e9ee07af12c ethernet --
我想使用nmcli. 我安装dnsmasq：
# sudo apt install dnsmasq
然后我建立了我的连接：
# nmcli con add type wifi ifname wlan0 mode ap con-name test ssid test ipv4.method shared
该命令似乎是成功的：
# nmcli con
NAME UUID TYPE DEVICE
MODEM 425b609c-c893-4178-b3c3-88a8f2124b33 gsm ttyUSB2
test f4936a89-11cd-4057-b481-1f62b776194b wifi wlan0

当我尝试连接到网络test时，我遇到了一些问题：
- 一台 Windows 10 机器设法连接，但它告诉没有互联网（而且我看不到分配给机器的任何有效 IP 地址）；
- Android机器无法连接
test，看来是IP分配有问题。
