Kubuntu 22.04无线连接提示“No secrets were provided”且重复要求输入正确密码的问题求助

大家好，我现在用Kubuntu 22.04遇到了个棘手的无线连接问题：
我的无线网卡是wlo1，连接名为TP-Link_6C21的WiFi时，一直提示**"No secrets were provided"**，还反复要求输入密码，但这个密码绝对没问题——Windows系统用它能立刻连上。

我查了些资料，有用户说是KDE钱包的问题，但我觉得不太对，要是钱包的话至少应该能连上一次吧？而且我用Lubuntu 22.04的live启动盘也连不上这个WiFi。

下面是我整理的排查信息，求各位大佬帮忙看看：

一、journalctl -f实时日志输出 #

rolfarius@rolfarius-VivoBook-ASUSLaptop-X513EA-K513EA:~$ journalctl -f

Jun 17 16:58:54 rolfarius-VivoBook-ASUSLaptop-X513EA-K513EA systemd[1]: NetworkManager-dispatcher.service: Deactivated successfully.

二、无线网卡软硬状态检查 #

用rfkill list确认了网卡没有被屏蔽：

0: asus-wlan: Wireless LAN
Soft blocked: no
Hard blocked: no
1: asus-bluetooth: Bluetooth
Soft blocked: no
Hard blocked: no
2: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
3: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no

三、手动配置wpa_supplicant的尝试结果 #

我试着手动生成配置文件测试，执行了这条命令：

echo -e "network={\nssid="TP-Link_6C21"\npsk="Your wlan password"\n}" > ~/wlan.conf

加载配置时得到了错误输出：

Successfully initialized wpa_supplicant Line 2: failed to parse ssid 'TP-Link_6C21'. Line 2: failed to parse ssid 'TP-Link_6C21'. Line 3: Invalid PSK '60269454'. Line 3: failed to parse psk '60269454'. Line 4: failed to parse network block. Failed to read or parse configuration '/home/rolfarius/wlan.conf'. : CTRL-EVENT-DSCP-POLICY clear_all

有没有大佬遇到过类似的情况？求支招！
