We have 2 PCs that are networked at home and a laptop which we usually connect when needed. When we are still using a dial-up internet connection, both PCs can access the internet using 1 connection but when we subscribed to a broadband connection, only the computer to which the LAN is connected can access the internet. Files and printer sharing works fine.

Do you have any suggestions on how can these 2 PCs (and the laptop) access the internet at the same time?
