    Ok so this has been happening for years, I just never wanted to buy a new one and test it out to see what the issue is but here it goes.

    I have a D-link wireless adapter model WUA-2340. I use it to connect to the internet on my desktop. Running windows 7 x64. although it did this back when I had xp on here as well.

    Sometimes it will be random but most of the times its when I'm downloading large files that take time to finish. So it'll be running between 1mb-3mbps download speed. Then randomly my connection will be lost, and the downloads will pause, even though my wireless adapter still has its blinking orange light as if its connected. My computers lil wireless logo in the tray will stay on as well until a certain point where it finally realizes that there is no connection and then the adapter will also have no light.

    What is the issue here and is there any fix from anyone who has experienced the same issue...is it my adapter or what?

    Thanks for any responses!

    Meaning that it has no power? Do you also get the "USB device has disconnected" sound?

    i don't think it loses power...i do not hear the usb device disconnected sound either. it simply stops blinking whenever it isn't connected to a network.

    Let's check for signal strength and possible interference ...

    Please attach a screen shot of the Networks page of the Xirrus Wi-Fi Inspector.

    Here it is. signal isn't terribly strong because it goes through 2 walls. but it only loses connection when i'm downloading big files fast.

    You're right; the signal is not strong enough for a reliable connection.

    Possible (not guaranteed) fixes include better antenna on router and/or adapter, reposition router and/or adapter, or an 'N' router.

    But why would it work fine all day long with no interruptions until I start downloading something at high speeds?

    I don't know; there may be problems other than the insufficiently strong signal. My guess is that you are losing packets all day long, but they are resent fast enough that you do not notice. But when the load goes up the number of bad or missing packets overwhelms the network. I suppose you could monitor your network at the packet level to see if this is true. It would be easier to move the computer to get a strong signal and then test to see if your downloads go smoothly or if there are still issues. That test would tell you whether you need to find some other cause in the computer or whether you need to work on the signal strength.
