Problems with 2 gateways in Vista

[NINJAZERO]

I'm on Vista 64 and I'm trying to get this to work like how it would in XP, but for some weird reason Vista doesn't seem to like how I set up my network configuration. I want to 2 default gateway ones is for my wireless adapter , and the other for connecting to my notebook through a giga nic card. I tried using RIP, but it doesn't seem to help. Every time I have both network device on one will take over, mostly the giga nic, but I want both of them running at the same time. I used the wireless mostly for internet and printing, and I use the giga nic to transfer files back and forth between my computer and notebook? Any one have a clue or a link that has the procedures to configuring my network under Vista to work like that?
