I've recently switched from iOS to Android on my smartphone, so I also
wanted to try the Android way of Winlinking again...

I will use [WoAD](https://woad.sumusltd.com/) for this.

stop network

sudo systemctl stop wpa_supplicant@wlan0.service

flush ip and routes

sudo ip addr flush dev wlan0
sudo ip route flush dev wlan0

set address

sudo ip address add 192.168.30.1/24 broadcast + dev wlan0

set as UP if not automatic

sudo ip link set dev wlan0 up

start dhcpd server

config:

option domain-name "mobile";
default-lease-time 600;
max-lease-time 7200;
authoritative;
log-facility local7;
subnet 192.168.30.0 netmask 255.255.255.0 {
option routers 192.168.30.1;
option subnet-mask 255.255.255.0;
option domain-name "mobile";
option domain-name-servers 192.168.30.1;
range 192.168.30.2 192.168.30.40;
}

start with

sudo systemctl start dhcp4.service

also start hostap service

sudo systemctl start hostapd.service

stop everything and brink back internet on wlan0

sudo systemctl stop {hostapd.service,dhcpd4.service}

sudo ip r flush dev wlan0
sudo ip a flush dev wlan0

check with `ip r` and `ip a` if they are empty

now again start wpa_supplicant @ wlan0 service

sudo systemctl start wpa_supplicant@wlan0.service

you should soon get your old ip address of the network back
