1. 操作指令

操作指令	说明	备注
softap_up SSID [PSK]	启动AP	其中psk为可选项，一般不设置
softap_down	关闭AP
cat /etc/wifi/hostapd.conf	查看AP的配置和SSID	可进行手动修改该文件
cat /etc/dnsmasq.conf	修改AP模式的网关IP地址

2. 启动AP

指令： softap_up SSID [PSK]

启动信息：设置了密码

root@TinaLinux:/usr# softap_up Jimmy1 12345678

4. 查看AP的SSID

指令：cat /etc/wifi/hostapd.conf

root@TinaLinux:/usr# cat /etc/wifi/hostapd.conf
interface=wlan0
driver=nl80211
ctrl_interface=/etc/wifi/hostapd
ssid=Jimmy1
channel=6
ieee80211n=1
hw_mode=g
ignore_broadcast_ssid=0
wpa=2
rsn_pairwise=CCMP
wpa_psk=d69b3f6f082b4d72cce00a8b7d77d17efa2388cb6d07d9da5075ae2f99b90e1e

5. 查看连接AP的设备

指令：cat /tmp/dhcp.leases

root@TinaLinux:/tmp/lib# cat /tmp/dhcp.leases
1605522948 e0:89:7e:a2:62:8c 192.168.99.3 Jimmy 01:e0:89:7e:a2:62:8c
1605522583 2c:6f:c9:33:9a:49 192.168.99.2 * 01:2c:6f:c9:33:9a:49

6. 修改AP模式的网关IP地址

修改 /etc/dnsmasq.conf 文件的 dhcp-range

# Change the following lines if you want dnsmasq to serve SRV
# records.
...
#cname=bertand,bert
resolv-file=/etc/resolv.dnsmasq.conf
strict-order
cache-size=102400
interface=wlan0
min-cache-ttl=3600
dhcp-range=192.168.1.2,192.168.1.255
all-servers
dhcp-sequential-ip

Notice：

此处的修改，一定是伴随着softap的修改，否则softap启动后，DHCP无法分配动态IP，导致PC无法连接板卡的AP
