我使用的是 Debian 8，WiFi 已停止工作。
当我通过 gnome 查找网络时，似乎没有可用的网络，我已经尝试了很多，但它不再起作用。
如果配置

我已经安装了驱动程序（它正在工作）我不知道为什么它停止工作。我不想格式化计算机
答案1
问题出在 wpa_supplicant.service 未启动。发现问题很容易后，使用一些命令一切正常。
wpa_supplicant.service 无法访问 libssl1.0.2
解决方案：
apt install --reinstall libssl1.0.2 <br>
service wpa_supplicant restart <br>
reboot
