问题描述

我刚接触Linux世界，现在遇到了一个棘手的问题：我的Beelink BT3-Pro迷你PC的Wi-Fi连接完全用不了，不过LAN网线连接是正常的。我能点击“开启”Wi-Fi，但之后完全没反应。之前装Elementary OS的时候也遇到过一模一样的问题，Windows 10下Wi-Fi可是完美运行的。

我现在用的是最新版Lubuntu，完全不懂Linux但非常想学习，希望有人能给我一步步的指导，告诉我该怎么做！

排查过程

我跟着网上的教程做了一些排查，以下是我的操作和结果：

执行命令lspci -nnk | grep -iA3 net; uname -r，得到网卡和内核版本信息：

01:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller [10ec:8168] (rev 0c)
Subsystem: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller [10ec:0123]
Kernel driver in use: r8169
Kernel modules: r8169
6.2.0-39-generic

执行lsusb查看USB设备：

Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 003: ID 093a:2510 Pixart Imaging, Inc. Optical Mouse
Bus 001 Device 002: ID 046d:c31c Logitech, Inc. Keyboard K120
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

用neofetch查看系统详细信息（这个命令真的很酷！）：

尝试加载网卡模块modprobe r8169，但终端没有任何反应。
运行无线信息收集脚本：

wget -N -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info &&
chmod +x wireless-info &&
./wireless-info

生成的日志已上传到pastebin。
6. 查看固件相关日志，执行sudo dmesg| grep -i firm; lsmod | grep cfg，结果显示固件加载失败：

另外我还看了这台机器的拆机视频，发现它没有可插拔的Wi-Fi网卡，没法通过重新插拔来排查。
