Qualcomm Atheros AR9485WB-EG 網路卡 wifi 無法運作

我最近在我的筆記型電腦上安裝了 Xubuntu,與 Windows 雙啟動。

在 Windows 端一切工作正常,但 Xubuntu 由於某種原因無法識別或無法存取我的網路卡,因此我無法連接到 wifi。我已經更新了核心和 Ubuntu 本身,我檢查了網卡的驅動程式更新,但找不到任何更新(它是 Qualcomm Atheros AR9485WB-EG)。

我對 Linux 和 Ubuntu 幾乎一無所知,所以我對如何解決這個問題一無所知,但我真的需要它盡快工作,所以我們將非常感謝所有幫助。

答案1

使用這個指令:

echo "blacklist acer_wmi" | sudo tee -a /etc/modprobe.d/blacklist.conf

然後這個:

sudo nano /etc/modprobe.d/ath9k.conf

設定選項

options ath9k nohwcrypt=1

然後儲存了,做了unblock all

rfkill unblock all

並重新啟動,現在工作正常。
