hey. i recently bought this: BELKIN HIGH-SPEED MODE WIRELESS G PCI CARD +4DBI OMNI-DIRECTION WIFI ANTENNA - MODEL: F5D70. However we have now upgraded to 50meg broadband and a new N router. But now the powermac G4 (dual 1ghz) wont pick up the router. I assume this is due to the G -> compatibility. Any solutions/suggestions?
