I followed the installation instructions for the DIR-600 but failed to complete the install. When the wizard on the installation CD ran, it made it through the first two steps but failed on step 3. In this step I see the message 'Waiting for Router...' and then after a few minutes it sends me to a page that suggests some steps to take next. So I tried installing the router manually but after everything is hooked up there is no WAN LED lit up. I can connect and log in to the router from my PC just fine but cannot get out on the internet. I tried two different ethernet cables between the 'Internet' connection on the router and the 'Internet' port on my cable modem but both had the same results. I know my cable modem is working because I can plug directly into it with my PC and get out to the internet. Any ideas what I should try next?
