我正在尝试双启动 Ubuntu 23.10 和 Windows 10。当我启动 Ubuntu 时，Wifi 连接后几秒钟就断开了。这种情况一直存在。
刚开始，我安装完 Ubuntu 后，Wifi 根本连不上。为了解决这个问题，我安装了一个驱动程序morrownr/8821cu-20210916来自 github。Wifi 工作了几个小时，然后开始每隔几秒钟连接和断开连接。我重启了很多次，并尝试重新安装驱动程序，但都没有用。
尝试修复：
- 我已禁用 Windows 10 上的快速启动。
- 将 Realtek Wifi 适配器移至计算机上的几个不同端口
- 在 Wifi 连接设置中禁用 ipv6
- 将其他 wifi 驱动程序列入黑名单，作为解决其他人类似问题的建议
可能的问题
有时 Ubuntu 和 Windows 上的时钟时间不正确，我尝试通过设置硬件时钟的时间来解决这个问题
我不确定驱动程序是否安装正确。我所做的就是：从 github 下载它，运行脚本
./install-driver.sh并保存默认配置文件。然后我运行命令sudo modprobe 8821cu
当我运行该命令时lsusb，我的 wifi 适配器显示为0bda:c811
请告诉我哪些命令输出对诊断问题有用。谢谢，Maverick。
