Networking Problem

I currently got a new broadband connection, and it was working fine on all three of my computers. Basic set up of Computers->Router->Modem. However, one recently started to get disconnected constantly. This isnt a total disconnect though, just enough to interrupt and stop a download, or disconnect you from a game. What possibilities are there?
Help!

you don't have to put it this way. the doctor really helped me when I was at this point of my life but it's not something you should say on the internet to make people feel bad :(
