What kind of broadband?
How many PCs/laptops do you wish to connect?
Do you wish to connect wired or wirelessly?
For most the solution is a Wireless Router with inbuilt 4 port switch. Router WAN port connects to broadband modem. PC connects to router LAN port. Log into router and set up wireless. Laptop then connects wirelessly if that's what you want.
