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

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev 
       ssid="wifi  id"

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.

  • I suppose you want to access the RasPi from your laptop. If you do not use an ethernet cable, how do you connect? By WiFi? Is there another access point/router? – Ingo Oct 15 '19 at 14:32

    Chances are that the power provided by your laptops's usb port isn't sufficient. Try using a proper psu. – Sim Son Oct 15 '19 at 16:40
