Qualcomm Atheros AR9485WB-EG 网卡 wifi 无法使用

我最近在我的笔记本电脑上安装了 Xubuntu，与 Windows 双启动。

在 Windows 端一切都运行正常，但 Xubuntu 不知为何无法识别或无法访问我的网卡，所以我无法连接到 wifi。我已经更新了内核和 Ubuntu 本身，我检查了网卡的驱动程序更新，但找不到任何更新（它是 Qualcomm Atheros AR9485WB-EG）。

我对 Linux 和 Ubuntu 几乎一无所知，所以我不知道如何解决这个问题，但我真的需要它尽快工作，所以我非常感谢所有的帮助。

使用了这个命令：

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

然后是这个：

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

设置选项

options ath9k nohwcrypt=1

然后保存了它，unblock all

rfkill unblock all

并重新启动，现在运行正常。
