I have a simple solution, and this is what I did at home.  I purchased a 
d-link hardware router with firewall.  It only costs between $20 and $40

Here are two links to tiger direct for this part:

You then connect up your pc to the router and then the router to the cable 
modem.  Make sure that the modem is powered off when you do this.  

When you bring everything up, the pc will get its internet connection from the  
router and it just works.

In fact, this router permits up to 4 pc's to share the connection (or more 
with an uplink cable) as well as providing a local dhcp service to your 
network.  Finally, you can set it up to provide you with network address 
translation so that your local machines are on a non-routable subnet.

The biggest benefit of something like this is that it increases your machine's 
security by providing an additional layer between you and the internet.
