I can't conect to the internet

Question

I have a Toshiba Satillite A35 laptop that I can't get to conect to the internet. Back story ... laptop was working fine, went to Euroupe for a month and while I was in Euroupe signed in on a "Other account" on my boyfriends UK desktop.

Since coming back to the states I can not connect to the IP provider plus all my lights are lit except for the hard drive.

Please help! This is my only conection to my European boyfriend and I miss him terribly.
