無線卡已列出但已停用

我在 PICO-KBU4 板上安裝了 WNFQ-258ACN(BT) 無線網路卡。它運行 Yocto Linux。

當我執行 ifconfig 時，沒有顯示無線介面。當我列出 PCI 設備時，它會顯示[已停用]：

# lspci -vnn

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

我已經加載了ath9k驅動。

# lsmod

為什麼顯示為禁用狀態？我怎樣才能啟用它？

編輯：

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

正如弗雷迪所提到的在評論中,9k不支援我的設備，所以解決方案是安裝th10k司機。
