I've ended up adding country=" and the country code to wpa_supplicant.conf` and also using system("systemctl daemon-reload && systemctl restart dhcpcd.service") whenever I change the network settings and it works nicely. I don't know which fixed it.

I've went into raspi-config and set a ssid and password and, as expected, wlan0 was assigned a dhcp IP. Then I've went into /etc/dhcpcd.conf and /etc/wpa_supplicant/wpa_supplicant.conf files and the only lines that were added were network={ ssid="MySSID" psk="Password1234" }

Also, systemctl daemon-reload && systemctl restart dhcpcd.service with root rights had no effect. wlan0 still doesnt' have any IP

But ip link set eth0 down && ip link set eth0 works. So, dhcpcd reconfigures the eth0 interface. Why isn't wlan0 working ?
