Two Hub Network Problem

Hey guys quick question. I have just expanded my network by placing a 4 port hub. The two computers that are connected to it are on the workgroup and see all the other computers on my network, but I cannot connect to the internet. I have double-checked all my ip, gateway, and DNS numbers and they are ok. If I put the computer back on the network it is able to use the internet again.

 

It does not work this way.

The Internet does not know where to go,

May be this can Help.
