我有带有 Wi-Fi 接入点 Hostapd + isc-dhcp-server 的 Ubuntu 22.04，每次我连接客户端时它都会在 2 秒后自动断开连接。
以下是 的内容/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
以及/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;
}
tail -f /var/log/syslog（dummyuser）的输出：

答案1
问题解决了。
我已将网关更改为 DHCP 服务器同一范围内的网关，客户端不再断开连接。
答案已从此处移至楼主的问题。
