well that sounds strange, but it is definatelt true that the speed in night gets automatically halve if you're downloadin big stuff.... i'm also experiencing the same for past few days..and about netexpert, the guy came to my place (now they have upgraded their soft which now support IE 7), insisted, and i allowed him to install. As soon he went out, i UNINSTALLED it... But before uninstalling, i reviewed the new net-expert, and definately it is a gr8 soft for noob/new/amet people...
