    Does anyone have any experience with a WiFi connection to an OBDII plug as opposed to a USB connection to the OBDII plug.

    I do know this:
    * wifi is established between devices (not between software). ie: the obdii connector and the laptop that I am using.
    * Techstream software is written independent of devices it is connected to.
    * Drivers connect the TEchstream software to the hardware (such as USB etc). Currently, for Techstream operating on Windows (any version), Microsoft provides the Drivers for Techstream data to be placed on the USB bus.

    So the question boils down to whether drivers for WiFi know where to fetch the commands issued by Techstream and know where to place the data once it is fetched from the CAN bus (located in the car).

    (please...no guessing....)

    the key would be the protocol the adapter supported vs what your car's protocol uses.
    Bluetooth vs USB has no bearing on CAN, K-Line, ISO, etc. Those define the structure of the data which is converted by the adapter into a USB or Bluetooth signal.

    Whether it works or not, there are a couple other issues to consider.

    1. Is the system on the laptop a supported version of Window$? Mine is running XP, so I keep the wifi turned off to provide an air gap against viruses.
    2. If wifi is on, Techstream will want to call home and will soon ask you to provide the authentication key.

    We have threads here that are way older than this one and still active and pertinent. :)
