WiFi infrastructure/ad-hoc mode?

    I have an infrastructure WiFi network at home with a Belkin router. My
    router is in the basement where there is also a desktop PC with a WiFi
    adapter. When I'm upstairs with my laptop I can get online but I can't
    connect to the desktop in the basement unless I'm in the basement with the
    laptop. This led me to the following question:

    In an infrastructure network, does client to client communication bypass the
    AP? That's what it seems like is happening. I thought the AP was like a
    switch and that all client communications had to go through it the same way
    a wired Ethernet switch works. But now I'm wondering if after Client A makes
    a connection with Client B via the AP, Client A from then on connects
    directly to Client B. I don't have either client set up for ad hoc. Does
    anyone know if this is the way 802.11b is supposed to work?

    Thank you.

    Your initial assumption is the correct one: in an infrastructure
    network, all communication goes through the router. It sounds as if you
    are connecting to someone else's wireless network when you are upstairs.

    Try this -- with laptop upstairs and connected to the Internet, go to
    basement and using desktop, access your router's configuration utility.
    Check the list of DHCP clients (assuming you have not set static IPs
    for your computers) to see if, in fact, your laptop is listed as being
