FreePBX 從命令行 WPA2 配置 wifi

我的電腦只有 Wifi 網路。沒有 RJ45 插座。我必須使用命令行配置 Wifi。我的無線網路：

Authentication         : WPA2-Personal
Cipher                 : CCMP
Connection mode        : Profile
Channel                : 1

在FreePBX我有文件/etc/wpa_supplicant/wpa_supplicant.conf：：

  ctrl_interface=/var/run/wpa_supplicant
  ctrl_interface_group=wheel
  network={
     ssid="mynetworkname"
     psk="mypassword"
  }

當我輸入命令時：

  wpa_supplicant -B -i wlan0 -c wpa_supplicant.conf -D wext

我得到錯誤：

Successfully initialized wpa_supplicant
Failed to open config file '/etc/wpa_supplicant.conf', error: No such file or directory
Delete '/var/run/wpa_supplicant/wlan0' manually if it is not used anymore
Failed to initialize control interface '/var/run/wpa_supplicant'.
You may have another wpa_supplicant process already running or the file was left by an unclean termination of wpa_supplicant in which case you will need to manually remove this file before starting wpa_supplicant again.

您應該提供配置文件的完整路徑wpa_supplicant.conf

killall wpa_supplicant
wpa_supplicant -B -i wlan0 -D wext -c /etc/wpa_supplicant/wpa_supplicant.conf
