Problems with my network. Help!

[Emil]

I got some problems with my network.

I got 2 network-cards in my computer. One is connected directly to my broadband. The other card is connected to a router.
I want to be able to share my broadband to the router and everyone who's connected to the router should be able to use the Internet.

I've changed the Windows Vista settings so I share Internet. If I login to the router is says "DHCP Client Connected" and everything seem to be fine.
But when I connect to the wireless-network with my laptop I still cant use the Internet.

Anyone got any ideas why?

(The reason I don't connect the router directly to the broadband is because the crappy D-link router is crashing if I'm downloading more than 10 megabyte/s.)

I have done everything I can think of with the router, it wont work when I download so I have to connect it this way.
