我正在尝试将我的 Fedora 38 盒配置为一个名为 的接入点（WiFi 热点）MyAP。
所以我nmcli这样使用：
nmcli -p con add type wifi con-name MyAP autoconnect yes ssid MyAp \
ipv6.method disabled ipv4.method shared ipv4.addresses 192.168.66.1/24 \
gw4 192.168.66.1 802-11-wireless.mode ap 802-11-wireless.band a \
wifi-sec.key-mgmt wpa-psk wifi-sec.psk <somepassword>
但是，MyAP连接/断开连接多次。在这种情况下，nmcli dev status显示：
DEVICE TYPE STATE CONNECTION
enp0s31f6 ethernet connected IMPA Wired
wlp0s20f3 wifi connecting (configuring) MyAP
p2p-dev-wlp0s20f3 wifi-p2p disconnected --
lo loopback unmanaged --
并且保持connecting (configuring)黄色。命令以黄色nmcli c显示MyAP连接。
我journalctl -b看到这些：

为什么MyAP无法連線？
编辑
如果我移除频带限制，它似乎会起作用802-11-wireless.band a。很奇怪，因为它以前用这个就可以工作。
