    Default How many Mw of transmit power does a standard Wi-Fi adapter /router have?

    I am struggling to connect to a Access Point (AP) from about 250-300 meters away with a standard USB dongle with SMA connector and a 12dbi external antenna in my loft and I only have around 20% connection despite the manufactures of my 12dbi antenna saying that the range would be considerably more .

    I was considering buying a 500mw adapter instead of my usb one and wondered would this increase my range and speed. ? And seriously boost my antenna performance and maximize its capabilities; or is 500mw of power pretty stranded and am wasting my time and money?

    Wouldn't it just be easier to move closer to the AP, or properly configure the wireless network with multiple AP's to provide adequate coverage for the area in which you're working?
    A third party security audit is the IT equivalent of a colonoscopy. It's long, intrusive, very uncomfortable, and when it's done, you'll have seen things you really didn't want to see, and you'll never forget that you've had one.

    Proper network design is preferred over excess RF, which just amounts to RF pollution.

    You're pretty much wasting your time and money. Just walk over to the coffee shop, buy some coffee and surf while you are there. 1000 feet is a pretty good stretch with normal wifi equipment and nothing in the way.
