这很烦人。2 个月前，我安装了 ubuntu 来替代 windows 10，原因是 windows 10 上的无线网络功能丢失了。我尝试了几乎所有可能的技巧，但都没有成功。然后我切换到 ubuntu，前 3-4 天运行良好，但突然出现了同样的问题。Wifi 突然自动关闭，重启后可能会工作，也可能不会。我现在该怎么办？
当我尝试获取我的无线信息脚本时，我发现了以下内容：
##### iwconfig ##########################
wwp0s29u1u2i1 no wireless extensions.
enp4s0 no wireless extensions.
lo no wireless extensions.
ppp0 no wireless extensions.
这与我的无无线问题有关吗？
的结果：
sudo lshw -C NetWork | grep -i wireless
我的硬件的无线信息：
