    I have a 500mb file on my mini. I am trying to copy it to my macbook over a wireless connection in my house, one that I have complete control over. It says 45 minutes. Really?

    Does it normally not take that long?
    200 KB/s is really slow, what kind of network do you have?
    And you can also check some settings via OPTION clicking the WiFi/AirPort icon in the Menu Bar, like PHY Mode and Transmit Rate.

    Yes, it always takes this long.

    The whole router thing is completely confusing. When I connect to my mini, why does the file transfer go through my router; why can't it just be a direct transfer? Isn't wireless N really fast in a local network?

    I tried the option click thing. Yours says Transmit Rate 243. Mine says 53. 53 what?

    Nature of the beast.

    Wireless to wireless transfers generally occur at a bit less than half the full bandwidth for the channel. Half is for System 1 -> Wireless Access Point/Router and the other half is for Wireless Access Point/Router -> System 2

    This rate still seems rather slow. How does your internet speed look like http://speedtest.net

    EDIT: read this for more about transfer rate: http://forums.macrumors.com/showthread.php?t=458405

    Do you have any old/legacy devices on your network?

    I'm running several Lion devices and a couple of xp boxes.
    Ping is 51ms.
    Download speed is 6.63mb/s
    Upload 3.92mp/s
    I'm using the basic router that Verizon fios installed; could that be it?

    Are the XP boxes by any chance on 802.11b/g?

    I believe they are on b/g

    So the whole network falls back to b/g. i.e. a max of 54 Mbit/s for g or 11 Mbit/s for b (careful if you are comparing Mbits to Mbytes too).

    Unfortunately you can't expect 802.11n speeds if you aren't running a pure 802.11n network.

    This may not be the main problem, but it certainly doesn't help.

    Thanks

    I believe WEP was running, which as I understand it can only operate at G. I'm on WPA now, so we'll see if it speeds things up.

    actually depending on router and such he can have a mix and still get n speeds with g on the network its called dual band my time capsule is dual band i can have g and n at the same time on the same frequency which i do but i also have the 2.4 abg/n and the 5 abgn which a lot of the older devices dont use

    True-ish, but:
    My understanding of how the Time Capsule implements "simultaneous dual band" is that it has separate radios for the 2.4 GHz and 5 GHz bands. You can dedicate the 5 GHz for 802.11n and run b/g/n at 2.4 GHz simultaneously. Many other 802.11n routers are dual band, including other Airport and Time Capsules, but they have to pick one or the other.
