I have connected the raspberry pi to the laptop without using Ethernet cable (I am getting power (5v) from the laptop). I have inserted a file in the SD card of Raspberry Pi for WiFi connection
country=IN
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
network={
ssid="wifi id"
psk="password"
key_mgmt=WPA-PSK
}
Both laptop and raspberry pi have same WiFi. initially I got the ip address and it works fine. But now the advance ip scanner is not showing the raspberry pi's ip address. Can anyone help.
