~$ turan

[spreadtrum]

执行以下指令将结果全部复制贴上来

代码： 全选

uname -a
cat /etc/issue
lspci -knn | grep -iA2 net
sudo lshw -numeric -C net
sudo iwlist scan

是不是跟我更新了系统有关呢？

能提供更新的内容则更好，即 /var/log/apt/history.log 的内容

这是什么原因呢？命令都是什么意思？

[vickycq]

iwlist scan 正常输出扫描结果。目前主贴图所示菜单有无列出扫描结果？若仍未列出扫描结果，尝试重启 NetworkManager, nm-applet

代码： 全选

sudo pkill nm-applet
sudo systemctl restart NetworkManager
nm-applet&

若仍未列出扫描结果，可查看执行以上代码过程中的系统日志寻找问题

这是什么原因呢？

原因待确定

命令都是什么意思？
