    Can we get a screenshot of your iwconfig? Were you actually running at 2000mw/33dBm

    Code:
    iw reg set BO

    In Linux Mint, iwconfig shows a transmit power of 30 dBm. My integrated adapter (Intel Wifi Link) shows 15 dBm so that should be about right (keep in mind the dB scale is logarithmic).

    33dBm is 2000mw give or take... 30dBm is 1000mw I believe... so 3dBm is a large difference in terms of wattage.

    I would try the above command (bring your card down first) and then report back, if still 30dBm, then I'm afraid you don't have a 2000mw card.

    I did use the above command, made no difference.
    Oh well, as I stated in my review, I think the whole miliwatt thing is becoming more and more like the megapixel race, where the general consumer consensus is "ZoMg moaaar megapixels, dis camera MUST be better!".

    Here's the thing though: The txpower scale is actually relative, not absolute. Despite the fact that it uses dBm/mW values, it doesn't mean that's actually what you are transmitting at; it's just a scale from 0-35 that is different on different cards.

    Did you notice the power level from the closest AP rising from -39 to -23? That's a huge difference due to the logarithmic dB scale.

    Also, hi fellow dutchman.

    That i did actually, but the range seems less. which seems weird to me. (ps that pictures was after i hung it on the wall, before it was allot worse)

    As an old Ham Radio operator,let me say that soldering are horrible,and smd mounting even worse!
    Look the Xtal and the usb and antennas connector for examples....
    Scratches everywhere...and this is the one from they took the pictures!
    No way...cheap components...short life!
    We are in the microwawe range...and not mentioning about the pcb..
