自从我买了新的笔记本电脑，配有英特尔无线 AC 9260 无线网卡后，我就无法连接到任何无线网络。当我选择要连接的网络时，它会尝试连接，但最后会显示连接超时之类的行为。你们中有人遇到过类似的问题吗？（是的，我已经进行了大量搜索以寻找相关问题，但任何解决方案都有效）。
附言：Windows 中的 Wi-Fi 连接工作正常。

尝试升级到一个新的稳定内核（假设您使用的是 x86_64）：
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.17.8/
创建一个新目录，然后从那里下载 linux amd64: headers all、headers generic、image generic 和 modules generic deb 包，然后 cd 到创建的目录并使用以下命令安装它们：
sudo dpkg -i *
然后做
sudo update-grub
然后用新内核重启你的笔记本电脑。这一定有帮助。
