Where can I find a wifi module with 5 V tolerant Digital I/O pins?

I'm in need of a surface mount wifi module with 5 V tolerant pins. Everything I've been able to find on google was either only 3.3 V tolerant or thru-hole. I've been digging through so many websites and data sheets and can't find anything. If anyone knows where I can find one, please help.

5V to 3V logic conversion can be as simple as a few resistors; there are level translator chips if you must.
Maybe you should use a USB interface and use a USB wifi adapter? If you can support wifi LAN protocol then you should be able to support USB protocol?
