    I have a Panasonic CF-31P model that had a single pass through antenna installed. I have changed out for a dual pass through antenna. However, BIOS still only shows configuration for the single pass through. Any suggestions for getting the BIOS updated for the new antenna configuration? I have already installed the only BIOS package I could find on panasonic.com support site.

    That's a new one to me.
    Usually they handle things like that automagically.

    Set to defaults...power pull reset.

    Is WAN physically attached to the passthrough? (jumper antenna wire) I don't know if it matters.

    My only dual pass is using 2.00L12/2.00L10. (bios/ec)

    Did you run one of these?

    The later mks need the antennas routed through the antenna control board.
    Has about 12 antenna connections on it.
    I think the CF31 senses the connected antennas and does it's magic.

    I've tried the wireless WAN antenna switch utility. It only sees the one antenna and won't let me force settings on the upper antenna with the command prompt option.

    The antenna wires are connected the same as my dual pass through computer.

    Is auto antenna switching enabled in BIOS?

    I've tried it both with built in and auto antenna.
