Yup, my guest is also software problem. The problem is that the wi-fi is on but it won't do any searching
It is just ON and that's it...Usually in a normal manner, whenever you set wi-fi to on, immediately it will search for Access points. But in my case, it just stood there without searching anything...(usually you know when it's searching by looking at the wi-fi's antenna icon. There will be arrows moving towards each other)....Really desperate here...
