我运行的机器在各自的驱动器上有两个操作系统（Windows 10 和 Pop!_OS 21.10），我大约一周前安装了 Pop!_OS，直到最近一切都正常工作。有一天，以太网停止工作，WiFi 也不再对我有用。任何使这两个/其中一个再次工作的帮助将不胜感激。
更新了解决方案：
ProtonVPN 有 3 个 Kill Switch 选项。关闭、开启和永久。它已切换为永久状态，除非连接了 VPN，否则即使 ProtonVPN 应用程序未运行，也会阻止所有流量。这也解释了为什么它在一周左右的时间内工作正常，并且在我安装 ProtonVPN 后就停止工作了。
我想知道这是否与 DHCP 租约或某种冲突有关，在这种冲突中，路由器会混淆两个不同的操作系统（在不同的时间）使用相同的硬件。
lspci告诉我我的以太网控制器是：
Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express 千兆位以太网控制器 (rev16)。
如果有帮助的话我的主板是技嘉科技有限公司的Z390 UD
通过查看此处有类似问题的帖子，我尝试/检查了以下内容：
- 重新启动我的路由器。
- Windows 快速启动被禁用（一直以来都是如此，但我仔细检查过）。
- 尝试在断开以太网电缆的情况下启动，然后在启动后将其插入。
- 当我启动 Windows 10 时，以太网工作正常。
查看 dmesg 的输出以查找可能相关的错误，我看到以下内容：
bcma: Unsupported SPROM revision: 11
bcma-pci-bridge 0000:03:00.0: bus0: Invalid SPROM read from the PCIe card, trying to use fallback SPROM
bcma-pci-bridge 0000:03:00.0: bus0: Using fallback SPROM failed (err -2)

此外，我无法使用我的 WiFi：Broadcom Inc BCM4352 802.11ac 无线网络适配器 [14e4:43b1] rev 03
在输出中dmesg我看到以下内容：

我不认为这些是相关的，但我注意到其他错误：
