MN500 setup using Vista

I just replaced my Windows XP desktop with Vista. Everything works except
router MN-500. I cannot surf net. I can access Internet if I remove the
router and connect DSL Modem to desktop. The setup is same as it was with my
old machine. Do I need to upgrade firmware or drivers of MN-500 for Vista?
If yes, where do I find more information on it? I tried resetting both modem
and router but no result.

Thank You,
