我打算使用“tuya-convert”在我的其中一台家用设备上刷新固件。我基本上安装了一些依赖项，然后运行了一个脚本，该脚本使用我的 Ubuntu 18 笔记本作为智能设备的热点。遗憾的是，重启后，我的 wifi 停止工作。它找不到任何网络，似乎已关闭。我尝试了很多方法，并在谷歌上搜索了很多，但我找不到解决方案。以太网仍然有效。

没有显示 Wifi。

它显示 Wi-Fi 已停用。它在设置中已启用。当然，飞行模式已关闭。
iwlist wlp3s0 扫描输出：
wlp3s0 Failed to read scan data : Network is down
运行“ifconfig wlp3s0 up”并重做“iwlist wlp3s0 scan”只输出“无扫描结果”。
rfkill 列出全部

我还尝试安装 Ubuntu ISO 并进入更新中心并检查“附加驱动程序”，但它不需要任何东西（通过以太网连接时）。
如您所见，我尝试了很多方法。有人知道发生了什么吗？
我将固件刷入智能家居设备时，却把一切都搞乱了：
git clone https://github.com/ct-Open-Source/tuya-convert
cd tuya-convert
sudo ./install_prereq.sh
（安装dnsmasq hostapd screen curl python3-pip python3-setuptools python3-wheel mosquitto haveged net-tools并运行sudo pip3 install paho-mqtt pyaes tornado）
然后我跑了
https://github.com/ct-Open-Source/tuya-convert/blob/master/start_flash.sh
一直到第 66 行。也许第 60 行在这里很有趣？
