Strange bandwidth oscillations

    I've been having this problem w/ wireless access to my home server for a while now. I honestly don't even know what keywords to search for to see if someone else has had this problem as well.

    When I open my laptop and click on a mapped network drive on the server, it takes ~20 seconds for the directory tree to pop up. Once it's up, navigation is smooth as usual. Once I leave it idle for a minute, the same long lag time on the first attempt to reconnect. If I try to stream a recorded video, sometimes I'll have no problems at all, at other times I'll have sufficient bandwidth (~300-500kps necessary to watch w/o hiccups) for 20-30 seconds, then bandwidth will tank for a while before going up again. I decided to test out transferring a large file and for the example below, I get similar behavior at the beginning of the file before the network decides to stop tripping over itself. But even then, the average transfer never reaches the capabilities of the network over wireless (~2MB/s). It gets there a few times, but it's like its lazy and doesn't want to stay there.

    So far I've just sucked it up and lived with this behavior, but I'm finally fed up and willing to put the effort into fixing it.

    Any ideas as to what's going on and what I should try/where I should go next to get to the bottom of this?

    Computer details:
    Laptop: XP Pro, SP3 1.8GHz Centrino
    Server: XP Home (it's all I have atm), SP3, 2.4GHz C2D
    Both computers were as good as idle during testing. The laptop (due to work restrictions) is on a different "workgroup" as the home server, but it was that way before I started having this problem about a year ago.
