Hi there. I bought this router with my old E220 modem. Now I have the new MF668 (I didn't check the compatability list - I know - my bad!) and now it doesn't recognise my modem. I've been through Netgear's Support system and their answer is that I must phone them (that will cost me a fortune) and troubleshoot it realtime. I run MacOSX. Is there a way around this to con the router into recognising my modem?
