I have bought new Inspiron N4050 and installed Windows 7 64 bit in it. It is not connecting to WiFi and whenever i turn on Wifi of my laptop the indicator light remains on for some time and then goes off. I checked control panel to see if any drivers missing . It showed only three drivers missing as shown in picture below then i serached for them on Dell Site by entering my service tag " " and tried installing 3 drivers one by one but none of them worked fine.Can anyone please help.
