    Googling "wifi usb dongle" returns 679,000 hits. 'Fraid you may be stuck with the programming.

    Do you need WIFI or just wireless? An easy way to get wireless with the protocol
    done is to use something like a MaxStream XBee which integrates a microcontroller
    and 2.4GHz radio. The XBee firmware implements the Zigbee protocol. To
    connect to an XBee you use a transmit and receive wire (RS232). You can get
    a USB to RS232 converter from FTDI. The XBee also has A/D plus DIO lines.
    Check out the O'Reilly book "Making Things Talk".

    I have developed a PCB that combines a USB + XBee radio. I also have some uC boards with XBee radios. Check out wiblocks.com for more information.
