Can I have multiple wifi networks on a single MacBook Pro? [[GoPro]] I'm looking to connect three GoPro cameras at the same time. Each GoPro needs its own network, and my computer needs to access all of them at the same time. Also, my computer needs a fourth wireless network of its own for accessing and uploading images to the internet. 

Can I do this? Is it possible to have multiple connections going on at once? Is there a USB wireless adapter I could buy that would accept multiple wifi cards?

EDIT: I need to access both GoPros at the same time. If I have gopro1 and gopro2, each with their own wifi configuration, I can only access one network at a time via my computer's dropdown wifi menu. Is there any way to connect to multiple GoPro networks at the same time? I need my computer to have it's own network so I can pull photos from each GoPro simultaneously.
Assuming those cameras work like the ones I've used, all you do is connect your computer and the cameras to the same Wi-Fi router, and you'll be able to do everything normally, on one network. You should never have to create multiple physical networks like that unless you're setting up a corporate network, with multiple access points.
