创建网络

在终端输入

IFNAME="wlan0"
CON_NAME="myhotspot" # wifi名称
nmcli con add type wifi ifname $IFNAME con-name $CON_NAME autoconnect yes ssid CON_NAME

设置wifi为共享

nmcli con modify $CON_NAME 802-11-wireless.mode ap 802-11-wireless.band bg ipv4.method shared

设置Wifi密码

mcli con modify $CON_NAME wifi-sec.key-mgmt wpa-psk
nmcli con modify $CON_NAME wifi-sec.psk "MyStrongHotspotPass"

开启Wifi

nmcli con up $CON_NAME

错误排除

rror: Connection activation failed: IP configuration could not be reserved (no available address, timeout, etc.)
Hint: use 'journalctl -xe NM_CONNECTION=5d927fb5-8aca-4114-932c-e5faed57fa5a + NM_DEVICE=wlan0' to get more details.

运行提示命令

journalctl -xe NM_CONNECTION=5d927fb5-8aca-4114-932c-e5faed57fa5a + NM_DEVICE=wlan0

发现缺少二进制文件

<warn>  [1712221130.5761] device (wlan0): ip:shared4: could not start dnsmasq: Could not find "dnsmasq" binary

下载相应缺失依赖

apt install dnsmasq

继续运行

nmcli con up $CON_NAME 

成功创建wifi
