optimize broadband speed

I don't think there is any software to optimise broadband speed. but there is this software called speedbit video accelerator that can improve video play speed for sites like youtube. is your C drive full? having lot of temporary junk files can slow down your connection. run disk cleanup atleast once a week. do not download files into c drive. if there are programs of more than 1 gb remove them to some other drive. If you think something is wrong with your modem, then you should call your connection providers.
