無線網卡已列出但已禁用

我在 PICO-KBU4 板上安裝了 WNFQ-258ACN(BT) 無線網卡。它正在執行 Yocto Linux。

當我進行 ifconfig 時，沒有無線介面出現。當我列出 PCI 設備時，它會顯示**$$ disabled $$**:

# lspci -vnn

01:00.0 Network controller [0280]: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter [168c:003e] (rev 32)

我已經載入了驅動程序ath9k。

# lsmod

為什麼它顯示為禁用？我該如何啟用它？

編輯：

root@aaeonc:~# rfkill list all
0: hci0: bluetooth
       Soft blocked: no
       Hard blocked: no

正如 Freddy在評論中提到的，ath9k不支持我的設備，所以解決方案是安裝ath10k驅動程序。
