In order to directly connect two computers (or your computer and modem 
in this case) together using ethernet, you need a special type of 
ethernet cable called a crossover cable - which is simply a normal 
ethernet cable wired slightly differently.

The cable you are using must not be a crossover cable - and so it works 
between a computer and a hub, but not directly between two computers.

You should be able to find more information on Google if you need it.

Hope that helps.
