Modem and wireless router configuration with desktop and wireless laptop

    I have a DSL modem with 4 LAN ports (provided by the ISP) and my own linksys wireless router (wrt54g).

    In the past they were configured like this:

    1 ISP DSL Modem
    __1.1 WRT
    ____1.1.1 wireless laptop
    ____1.1.2 wired desktop

    I observed that if the desktop is connected directly to the modem, the internet desktop performance is better. Since I usually spend more time connected to internet via desktop than via laptop (downloads, etc) I changed the configuration to this:

    1 ISP DSL Modem
    __1.1 wired desktop
    __1.2 WRT
    ____1.2.1 wireless laptop

    Because of this, the 2 PC's are now in different networks; the laptop can ping the desktop, but the desktop cannot ping the laptop, not even the WRT (I tried pinging both WAN interface and internal IP).

    Both PC's can access the internet, however, I would like to have access between them as if they were in the same physical network (network sharing, etc).

    How should I configure the WRT?

    Few things that might help you to understand better:
    - WRT is having a hyperwrt firmware, configured as Gateway, default routing table, no extra configurations
    - Modem lan port connects to WAN port of WRT

    Thanks a lot for your help.
    PS: please excuse if duplicate with other threads, I looked in the current posts but couldn't find something similar.
