I enjoyed browsing very fast from my home computer until last few days using WiFi. I could even able to browse in sitting at my open terrace. While traveling in Chennai roads too there was lot of wi-fi services connected to my mobile. But for the past two days it was dead and not connecting to. It just blinks green and goes off. I could not figure it out where the knot is. While connecting to "Add WiFi network" it asks for 1. "Net work SSID" square box. And I do not know what to type there. 2. Security.... what to type? 3. Wireless password...that i know XXXXX It says "unable to scan networks".... Why? It was all good for the past two weeks. Now only the issue arises. Is it of BSNL (my service provider) side issue or my side?
