Building LAN with android phone (Xiaomi Redmi 3s)
If you have more information, I can help you.
The APP ES file explorer provides a LAN function.
If you want to route over the PC to a router or something do this.

1.)First, you need to enable routing.(Windows)

2.)You need an app that provides you with a terminal (terminal emulator etc.)

Example:
ifconfig usb0 192.168.0.2
route add default gw 192.168.0.1


Set your DNS server :

echo "nameserver 8.8.8.8" &gt;&gt; /etc/resolv.conf


or with BusyBox:

nano /etc/resolv.conf


3.)Under Windows you need to configure the path to your router.

route ADD 192.168.0.2 MASK 255.255.255.0 192.168.0.1
