Ubuntu 20.04 服务器上带有 hostapd 的接入点不允许客户端连接

我有一台 ubuntu 网关服务器，上面有 2 个网卡，一个用于互联网，一个用于局域网。我刚刚在无线设备上设置了无线接入点，hostapd但客户端无法连接到它，日志中出现以下错误：

Dec 12 10:08:56 localhost hostapd: wlp6s0: STA 84:cf:bf:91:d8:35 IEEE 802.11: authenticated
Dec 12 10:08:56 localhost hostapd: wlp6s0: STA 84:cf:bf:91:d8:35 IEEE 802.11: associated (aid 1)
Dec 12 10:09:05 localhost hostapd: wlp6s0: STA 84:cf:bf:91:d8:35 IEEE 802.11: deauthenticated due to local deauth request

到目前为止，我已经设法通过猜测和在各个地方寻找单独的步骤来完成配置，因为我找不到任何涵盖 ubuntu、netplan和 的操作指南hostapd。

这是我的设置：

hostapd.conf：

adam@gondolin:~$ cat /etc/hostapd/hostapd.conf 
interface=wlp6s0
driver=nl80211
bridge=br0
ssid=Anduin
hw_mode=g
channel=1
macaddr_acl=0
auth_algs=1
ignore_broadcast_ssid=0
wpa=3
wpa_passphrase=secret123
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP
rsn_pairwise=CCMP

网络计划：

adam@gondolin:~$ cat /etc/netplan/01-netcfg.yaml
# This file describes the network interfaces available on your system
# For more information, see netplan(5).
network:
  version: 2
  renderer: networkd
  ethernets:
    enp5s0:
      dhcp4: yes
      dhcp6: yes
    eno1:
      addresses:
      - fe80::10/128
      - 192.168.0.3/24
      dhcp4: no
      dhcp6: no
    wlp6s0:
      dhcp4: no
      dhcp6: no

仍然不清楚为什么会出现取消认证消息，但是我hostapd通过在 netplan 中设置桥接解决了这个问题。

adam@gondolin:~$ cat /etc/netplan/01-netcfg.yaml
