Windows 7: multiple simultaneous wireless connections?

Is it possible to connect a computer with a single WLAN card to two different routers simultaneously? I want to know if I can connect to my router that's connected to my cable modem and also to a router that is connected to a slingbox. I only plan to use the slingbox within my house and I don't want to connect it to the Internet because I think I will exceed my monthly bandwidth usage.

Short answer... No.

You would need two wireless cards to do that.

okay, thanks. I thought I read somewhere that there was a program that let the card act as multiple cards.

There might well be... but I'll bet you three manhole covers it's flakey as all get out.

These things are not designed for spread spectrum or RF multitasking.

thanks again for your help. I was really just hoping more than anything. Looks like I'm in the market for a new LAN card.
