Theoretically yes, but you would need a real router, where every port has it's own network.Is there anyway to make it work without a wireless card?
I only have my router, and can't make it.

Then you would connect your PC twice to the router, so you would have 2 different IP addresses on different networks.
Then you have to configure the router, that it transmits all the wifi data to one of the ports that are connected to the pc, the pc has shares the second connection to the one that is connected to the above said one, and the last step would be that the router routes all the traffic it receives from the second pc port (not the one that leads to the wifi) to the internet.
A picture to make it clear:
