    Show for both when you are trying to connect both ...

    Start, Run, CMD, OK to open a command prompt:
    (For Vista or 7 type CMD in the Search box after Start)

    Type the following command:

    IPCONFIG /ALL

    [Note that there is no space between the slash and ALL.]

    Right click in the command window and choose Select All, then hit Enter.
    Paste the results in a message here.

    If necessary use a text file and removable media to copy the results to a computer with internet access.

    I'm confused about what your network is like after looking at the ipconfig /all for Jacky-PC. It has an apparent wireless connection to a router, but also a PPP connection I guess to your modem. Please describe your network, including brand and model of modem, router, etc., and how all devices are interconnected.

    Can't tell anything about the 2nd PC 'cause all those tunnel adapters cut off the useful beginning of the output. For that computer either capture the output in a text file (ipconfig /all > config.txt) and then just copy the beginning (up to the first tunnel adapter) here, or else get rid of those tunnel annoyances, per the registry tweak as follows.

    You can disable IPv6 in Windows Vista [or 7] by doing one of the following:

    In the Connections and Adapters folder, obtain properties on all of your connections and adapters and clear the check box next to the Internet Protocol version 6 (TCP/IPv6) component in the list under This connection uses the following items. This method disables IPv6 on your LAN interfaces and connections, but does not disable IPv6 on tunnel interfaces or the IPv6 loopback interface.

    Add the following registry value (DWORD type) set to 0xFF:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\DisabledComponents (DisabledComponents)

    This method disables IPv6 on all your LAN interfaces, connections, and tunnel interfaces but does not disable the IPv6 loopback interface. You must restart the computer for this registry value to take effect.

    My modem is a speedtouch 516 v6
    my router is a linksys WRT54G
    Both laptops are wireless and are not connected to the net by wire
    The modem's ethernet port is connected to the router's internet port by a wire
    The DSL port of the modem is connect to my "phone port" and that's everything
    Do you want to see the "new" ipconfig/all of the second laptop?

    The Speedtouch 516 is a DSL modem/router combination unit. I'm guessing that it's configured in a bridge or bypass mode--acting as a modem only. If that is the case then the PPPoE (and I assume account/password info) should be configured in the Linksys's WAN (Internet) section, not on your computers.

    If the Speedtouch is configured as both modem and router then the PPP info would be in it's WAN section, and both the Linksys and computers would use a simple dynamic connection. However, there would then be another problem--both router's default to using the same LAN IP subnet and one would have to be changed.

    You're asking about changing the LAN subnet used? Change whichever one is easier for you. I always suggest 192.168.3.x, but there are numerous equally good.

    I changed the router's local IP address. What should I do now?

    Take the PPP stuff off the computer(s).
