What about all the other machine drivers? You didn't tell.
I've a Airtel Broadband connection with a Beetel WiFi Router. I've installed Windows Vista on my laptop. Though the network icon in the Task Bar shows that its connected I'm not able to connect to the internet. I've tried different browsers but failed. Also I've tried to ping websites in command prompt even that is not working. Please help me with any settings to be done. The connection works absolutely fine on my brother's Dell laptop hence I'm sure that there is no problem with the Router.
