First off, if you plug the modem directly into the computer do you have Internet access?
If not, first diagnose and repair the modem issue with Wild Blue tech support.
Once you know that the modem connects, verify that the modem is plugged into the WAN port on the router.
Start with a PC connected with a CAT5 cable to any of the LAN ports on the router.
Download and print any configuration instructions from Wild Blue for router setup. Have the Linksys manual handy.
Open up your browser and key in the address for the router configuration page.
Make sure that all of the configurations are set correctly including your Wild Blue user name and password if required.
If you are still having problems, try calling Linksys tech support. They at least used to know the specific setup requirements for most modems.
