我只是尝试使用命令行连接到我的 WPA2 网络。过去几个小时我尝试了各种方法，但都没有成功。
尝试 #1
因此我尝试使用/etc/network/interfaces以下信息编辑该文件：
auto wlan0
iface wlan0 inet dhcp
wpa-ssid "my ssid with spaces"
wpa-psk "my cleartext password"
ifconfig down尝试使用和关闭接口ifup -v wlan0，结果出现以下错误：
ifup: configuring interface wlan0=wlan0 (inet)

wpa_supplicant: /sbin/wpa_supplicant daemon failed to start
run-parts: /etc/network/if-pre-up.d/wpasupplicant exited with return code 1
ifup: failed to bring up wlan0
尝试＃2
接下来，我尝试使用 wpa_supplicant。
# wpa_passphrase "my ssid with spaces" >> /etc/wpa_supplicant.conf
<my cleartext password followed by Enter>
我尝试使用以下命令启动 wpa_supplicant：wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf -Dnl80211仅显示以下输出：
Successfully initialized wpa_supplicant
wlan0: CTRL-EVENT-SCAN-FAILED ret=-16 retry=1

^Cnl80211: deinit ifname=wlan0 disabled_11b_rates=0

尝试＃3
我也尝试过仅从命令行使用iwconfig，但这也不起作用：
# iwconfig wlan0 essid "my ssid with spaces" key "cleartext password"
Error for wireless request "Set Encode" (8B2A) :
invalid argument "cleartext password".
尝试#4
不确定我做了什么不同的事情，但现在wpa_supplicant似乎与我的 AP 关联，然后又断开了关联。我已经验证了密码是否正确。以下是在命令行参数中未指定驱动程序的情况下运行它的输出：

尝试＃5
现在我尝试使用wpa_cli，它似乎正在关联，但又断开了关联。我看到 auth_failure = 1，但这不可能正确，因为我只是将密码粘贴到笔记本电脑上并连接正常，将其粘贴到 CLI 中却失败了。

我做错了什么？似乎仅仅通过命令行连接到 Wi-Fi 就非常困难。我正在使用技嘉迷你电脑。
任何帮助将不胜感激。
