我正在看 YouTube，突然我的互联网连接中断了。我检查了网络，现在 wifi 检测不到任何无线网络：
网络截图 我已经尝试过 wicd 但也没有检测到任何东西。
这是我的无线网卡：
dani@danism-debian:~$ lspci | grep Wireless
00:14.3 Network controller: Intel Corporation Wireless-AC 9560 [Jefferson Peak] (rev 10)
ifconfig 的输出如下：

有线连接可以工作。我尝试重新安装网络管理器，但仍然不起作用。
我的 Debian 版本是 10
更新：
我用 lshw 检查了我的系统，无线网卡显示为 UNCLAIMED。我不知道那是什么意思，但似乎是问题的根源：
