安装更新后 Wi-Fi 适配器不工作

安装更新后 Wi-Fi 适配器不工作

我在用着Ubuntu 14.04我最近使用 Muon 更新管理器安装了更新(包括内核更新)。现在我的 Wi-fi 适配器无法正常工作。

我希望这些输出能有所帮助:

我也看过这个类似的问题这里但它似乎适用于旧版本的 Ubuntu。

答案1

运行以下命令来禁用此处可能发生冲突的错误驱动程序:

sudo rmmod ath3k

然后运行以下命令确保输入每一个字母此命令以免覆盖整个文件:

echo "blacklist ath3k" | sudo tee -a /etc/modprobe.d/blacklist.conf
