1. Connect the WD MyBook to the Linksys router using USB cable.
2. Open the admin interface using the browser. In the Storage tab create a new share.
3. Make sure that All Partitions share is selected.
4. Open the finder and browse to the Network -> MsHome folder. Click on Linksyswrt350N and select the share that you created. Click ok. Now you can view the external drive from all the computers connected to the router.
Still have not figured out how to pick up the changes on the external drive from the computer that did change it. I have to reconnect to see the modifications. There has to be a better way.
