最近我弄乱了子网设置。我做了不同的更改，如下所示
sudo ip address del 172.23.99.15/18 dev wlo1
sudo ip address add 172.16.0.0/14 dev wlo1
sudo ip address add 172.20.0.0/15 dev wlo1
sudo ip address add 172.22.0.0/16 dev wlo1
sudo ip address add 172.23.0.0/18 dev wlo1
sudo ip address add 172.23.128.0/17 dev wlo1
sudo ip address add 172.24.0.0/13 dev wlo1
现在，当我尝试将我的 PC 连接到特定路由器时，我无法连接，但我的 Android 手机和 Windows 操作系统可以。此问题仅存在于特定路由器中，而不是所有路由器。与此路由器的有线连接也失败了。这是ifconfig输出
