I am having a Compaq Presario V3231AU. It has Windows Vista business edition in it. I am getting a wifi problem with the laptop. I bought it second hand. And at the time of buying I had checked everything was working well. But suddenly the wifi stopped work. There is nothing I can do. I was using Wifi from long time. But recently I stopped using it. It is now almost after a month when I turned it on HP Wifi Assistant is not able to find any connectivity. It is very annoying. I am not able to find any active connection here and I am not at all satisfied with the same. The signal which is detected in the laptop is quiet strong. But it fails to work actively. I hope there will be some kind of working solution for the same.
