Computer randomly disconnects from internet for seemingly no reason

[Whatsinaname]

At random intervals, my computer will just decide that my connection to the internet is non-existent. However, I know this is bullshit because all I have to do is disconnect from the network and reconnect, and it immediately starts working again. Then it will tell me I can't connect anymore and I have to do the same thing again. Sometimes I can stay connected for over an hour, other times it takes me offline in seconds. Also, my 360 and PS3 can connect just fine.

What could possibly be happening?

Hmm, let me guess - you're using wireless?

Yes.

You may have some issues with your wireless adapter.

Which one is it?
