The screen shot of my device looks like this:
Could anyone help me to know the MAC and IP Addresses please? My device runs Android ICS.
You can get the MAC address from Settings > About > Hardware Information. IP address will only appear on the page shown on your screenshot once you have connected to the wifi dhcp server. Another way to find out IP is to use the browser and go to the website www.whatsmyip.org/ - this will tell you the address your router is on however, and not your local (wifi) network IP.
Install this application, it may help you to get IP and MAC.
