(In the voice of johnny 5) "Need more INPUT"
Such as...conneciton to modem, router involved? Connection to router? IP Address (full, althogh may want to XX out a single octet of public IP), including gateway and DNS.
To start with, I would always start by pinging the default gateway, then the DNS servers (by IP) and then an web site (by IP, write down beforehand) and website by name.
THen you can see where the drop is at easier.
