A router is a device that is needed to share a connection wirelessly... it is a small box that the original wire comming into the house is pluged into...

does your laptop got a internet wire going into the back??? or is it wireless now??? if it is wireless now then you have a router...

if so we can continue if not get a wireless router...

Routers are what they are named they route the internet to others on a network,which is what U need...
