Ubuntu 上 Wifi 已连接但无法访问互联网,Windows 双启动时运行正常

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:

Network:
  Device-1: Intel Dual Band Wireless-AC 3168NGW [Stone Peak] driver: iwlwifi
  Device-2: Realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet
    driver: r8169
