编辑：已通过@libnull-dev 在评论中解决。更改路由器安全设置解决了该问题。此外，感谢@libnull-dev，我了解到尽管 Pop_OS! 是基于 Ubuntu 构建的，但记录相关问题的最佳位置是在Pos_OS！github 问题跟踪器。
编辑 2：还发现了一个很棒的无线信息脚本以帮助提供更好的信息来诊断无线问题。来自评论：
wget -N -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info && chmod +x wireless-info && ./wireless-info
我在故障排除过程中遇到了困难，需要调试帮助。
跑步流行操作系统！ 19.10在联想 ThinkPad x1 Extreme。它无法连接到我的家庭网络。我将桌面更新为 Ubuntu 19.10，连接良好。笔记本电脑与 Windows 10 双启动，也可以连接。路由器没有任何变化，尽管我将其恢复出厂设置以确保安全，但没有成功。
笔记本电脑连接和未连接时的唯一变量是 19.04 -> 19.10
以下是我的日志的 TL;DR，包括
journalctl -b | grep wifilspci -nnk | grep 0280 -A3dmesg | grep -e wl -e iwllshw -C networkcat /var/log/syslog | grep iwlwifisystemctl status network-manager连接失败和成功的情况（分别为家庭网络和 iPhone 网络共享）
如果我应该添加其他信息，我很乐意提供。
我知道的一个错误是BIOS contains WGDS but not WRDS。我相信这是一个阻止计算机完全挂起的问题，并已通过以下方式解决在唤醒时切换 XHC，但我仍然在系统日志中看到该消息。
journalctl -b | grep wifi
