我的台式机双启动，Windows 和 Ubuntu 22.04。我以前遇到过这个问题，但之前它就消失了。问题是，我的频谱 wifi 连接到同一设备上的所有设备，包括 Windows，但不能连接到 Ubuntu。它曾经工作了一年多，但由于某种原因，它停止了工作。
我想要一些关于如何诊断这个问题的意见。而且它以一种奇怪的方式连接。当我重新启动网络服务时，我可以短暂地访问互联网，然后就黑屏了。此外，wifi 可以连接，但我无法访问任何网站。
这是 inxi -N 的输出：

Device-1: Intel Dual Band Wireless-AC 3168NGW [Stone Peak] driver: iwlwifi
Device-2: Realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet
