![Debian - 全新安装后没有 WiFi](https://linux22.com/image/100607/Debian%20-%20%E5%85%A8%E6%96%B0%E5%AE%89%E8%A3%85%E5%90%8E%E6%B2%A1%E6%9C%89%20WiFi.png)
我刚刚在我的系统上安装了 Debian Stretch。我必须将所有驱动程序加载到另一个 USB 棒上才能使 WiFi 棒正常工作,但当它最终接受 USB 时,我在安装时可以上网。
然而,第一次重新启动后,我收到一条错误消息,提示我无法连接到我的 WiFi。所以我查看了设置,但似乎没有什么问题。我重新输入密码,发现“保存”按钮呈灰色。它显示:“Wi-Fi 设置无效:MAC 地址无效...”。果然,在您可以输入 MAC 地址的字段中显示“永久”。所以我清空了该字段,但重新连接仍然失败。我刚拿到旋转器,它最终放弃了:

我的无线局域网配置如下所示:
我还尝试了手动连接,如 debian wiki wiki.debian[dot]org WiFi HowToUse 中所述,但ifup wlx7cdd905ca7ad
仅输出:
wpa_supplicant: /sbin/wpa_supplicant daemon failed to start
run-parts: /etc/network/if-pre-up.d/wpasupplicant exited with return code 1

尝试禁用随机 MAC 地址随机化:将以下内容添加到 /etc/NetworkManager/NetworkManager.conf 并重新启动 NetworkManager.service:
[设备] wifi.scan-rand-mac-address=no
