Are there usb wireless cards that will work

[n612ua]

Hello I have a gateway 7811fx with an intel 5100 wireless card that from all the searching i've done don't work on mac. I am running 10.5.8 maybe I can find away to get snow leopard to install all though that won't fix this problem. Are there any usb wireless internet cards that will work on 10.5.8?

Thanks mike
