我在旧笔记本电脑上安装了 Ubuntu 16.04，但无法进行无线连接
sudo ifconfig wlp3s0 up
mm@6830s:~$ sudo iwlist wlp3s0 scan
wlp3s0 Interface doesn't support scanning : Invalid argument
一切似乎都好
sudo lshw -class network
*-network

logical name: wlp3s0

我的界面
cat /etc/network/interfaces
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback
auto ens5
iface ens5 inet dhcp
auto wlp3s0
iface wlp3s0 inet dhcp
如果我去
sudo iw dev wlp3s0 scan
command failed: Invalid argument (-22)
如何解决这个问题？
