默认系统自带的方法中没有定义192.168.137.1的方法，得自己写个脚本
start_wifi.sh
#!/bin/bash
set -euo pipefail# ==== 可改参数 ====
HOTSPOT_NAME="MyHotspot" # 连接配置名（任意，用来管理）
HOTSPOT_SSID="UOS_Hotspot" # Wi-Fi 名称

IP_ADDR_CIDR="192.168.137.1/24"
# 若你确定网卡名，直接写：WIFI_IFACE="wlp2s0"
WIFI_IFACE="${WIFI_IFACE:-}"# ==== 要 root 权限 ====
#if [[ $EUID -ne 0 ]]; then
# echo "[*] 需要 root 权限，正在使用 sudo..."
# exec sudo WIFI_IFACE="${WIFI_IFACE}" IP_ADDR_CIDR="${IP_ADDR_CIDR}" \

if [[ $EUID -ne 0 ]]; thenSELF="$(readlink -f "$0")"# -n 禁止交互（如果 sudoers 配置正确，会立即成功；否则会直接返回错误）exec sudo -n HOTSPOT_NAME="$HOTSPOT_NAME" HOTSPOT_SSID="$HOTSPOT_SSID" \HOTSPOT_PASS="$HOTSPOT_PASS" IP_ADDR_CIDR="$IP_ADDR_CIDR" \WIFI_IFACE="$WIFI_IFACE" bash "$SELF" "$@"

但是每次要输入管理员密码，不爽，
sudo visudo -f /etc/sudoers.d/wifi-scripts
加入如下内容
User ALL=(root) NOPASSWD: /home/User/LINUX/start_wifi.sh, /home/User/LINUX/stop_wifi.sh, /home/User/LINUX/start_hotspot.sh之后调用时用
sudo ./start_wifi.sh
就不用输入密码了
