我想我已經看過任何其他提出這個問題的線程 - 我已經被這個問題困擾了很長一段時間。
當我啟動系統（Kali Linux Rolling）時，出現錯誤Raise Network Interface [Failed]並systemctl status networking.service輸出：
# systemctl status networking.service
● networking.service - Raise network interfaces

我的網卡是Network controller: Qualcomm Atheros AR9287 Wireless Network Adapter (PCI-Express) (rev 01).我的網卡是新的，但當周圍明顯有網路時，我看不到任何網路顯示（它曾經有效，但不知何故，現在不起作用）。
以下是一些命令的輸出，這些輸出將洩露有關該場景的一些有用資訊：
# iwconfig

# rfkill list

我已經遇到這個問題很長一段時間了，有什麼辦法可以解決這個問題並使我的 WiFi 再次工作嗎？
