手动设置wpa_supplicant驱动程序？

我使用的是 RaspberryPi 4 (4GB)，我能够/etc/wpa_supplicant/wpa_supplicant.conf正确设置所有需要的证书，以在我们公司的 wifi 上进行身份验证：

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=US

fast_reauth=1

network={
    ssid="WIFI-Com"
    scan_ssid=1
    key_mgmt=WPA-EAP IEEE8021X
    pairwise=CCMP
    group=CCMP
    eap=TLS
    identity="[email protected]"
    ca_cert="/etc/cert/ca.pem"
    client_cert="/etc/cert/client.pem"
    private_key="/etc/cert/clientkey.pem"
}


用于wpa_supplicant -i wlan0 -D wext -c /etc/wpa_supplicant/wpa_supplicant.conf测试，认证完美，获取有效IP：

如果我重新启动 Pi 并运行ps auxwww | grep wpa它应该连接到我的 wifi，因为它使用上面给出的命令。但事实并非如此，它使用了 driver nl80211。根据我的经验，只有使用专有的-D wext.在哪里可以编辑-D启动时使用的参数？

root       334  ..   0:00 /sbin/wpa_supplicant -u -s -O /run/wpa_supplicant
root       440  ..   0:00 wpa_supplicant -B -c/etc/wpa_supplicant/wpa_supplicant.conf -iwlan0 -Dnl80211,wext
pi         721  ..   0:00 grep --color=auto wpa

答案1

/lib/dhcpcd/dhcpcd-hooks/10-wpa_supplicant您只需添加即可，而不是修改

env wpa_supplicant_driver=wext

到 结束/etc/dhcpcd.conf。

答案2

我能弄清楚。由于某种原因，它使用了nl80211代替，wext并且我删除了nl80211中的每个条目/lib/dhcpcd/dhcpcd-hooks/10-wpa_supplicant。

非常特殊的情况，也许不是常见的方式，但成功了。
