Ubuntu 22.04下Hostapd+isc-dhcp-server搭建的WiFi热点客户端认证2秒后自动断开问题求助

各位大佬好！我在Ubuntu 22.04上用Hostapd搭配isc-dhcp-server搭建了一个WiFi热点，但遇到了一个棘手的问题——客户端成功连接并完成认证后，总是在2秒左右就自动断开，然后又反复尝试重连。我已经检查了配置文件和日志，但还是找不到问题所在，希望大家能帮我分析一下！

一、Hostapd配置文件内容 #

路径：/etc/hostapd/hostapd.conf

interface=wlp3s0
hw_mode=g
channel=10
ieee80211d=1
country_code=FR
ieee80211n=1
wmm_enabled=1
ssid=somename
auth_algs=1
wpa=2
wpa_key_mgmt=WPA-PSK
rsn_pairwise=CCMP
wpa_passphrase=somepassword

二、DHCP服务器配置文件内容 #

路径：/etc/dhcp/dhcpd.conf

option domain-name-servers 8.8.8.8, 8.8.4.4;
default-lease-time 600;
max-lease-time 7200;
authoritative;
subnet 10.10.10.0 netmask 255.255.255.0 {
interface wlp3s0;
range 10.10.10.100 10.10.10.125;
option routers 192.168.1.1;
option subnet-mask 255.255.255.0;
}

三、系统日志输出（tail -f /var/log/syslog） #
