Getting 2 (W)LAN's talking

    I am trying to work out how to:
    • get my WLAN to connect to my friend accross the street's WLAN
    • so that we can share data (example see \\192.16.1.2\Shared Folder\ from 192.168.0.2)
    • our (W)LAN devices still use the gateway IP of our WLAN Router as set by DHCP
    • and doing this wireless so we are not using out internet bandwidth
    This diagram may help understand what I am trying to do:
    Code:
    {192.168.0.2} {192.168.0.3}
          └------┬------┘
           {192.168.0.1}
           [WLAN ROUTER]-[ADSL MODEM]-{INTERNET}
                 |
                ???
                 |
           [WLAN ROUTER]-[ADSL MODEM]-{INTERNET}
           {192.168.1.1}
           ┌-----┴------┐
    {192.168.1.2} {192.168.1.3}
    Is this possible between the two WLAN Routers?
    I have tried looking into things like WDS & Bridging but not sure if they do what I am trying to do?

    Any assistance would be greatly appreciated.

    Thanks,
    Ka Hooli

    undesired solution

    I have been looking into this a bit more...

    I would rather do this between the WLAN routers themselfs but...

    it looks like I might have to setup a server (ie a linux box) to connect from ethernet on one LAN and route to the other network via WLAN.

    I am still open to any ideas from anyone as it may lead to a solution.

    Thanks,
    Ka Hooli

    i've never tried this but have you tried adding a static route to each others LAN address in advanced routing setup in the WRT's? then attach a ethernet cable between 2 LAN ports? i'm only guessing but its worth a try.

    Toxic that is completely doable if they could cable them together, from what i get they are across the street from each other and a cable is not possible. Now a couple things that come to mind. What you really want is a tunnel between the two, some of the 3rd party firmware will allow you to turn the wrt's into pptp servers, not exactly what you want but will allow you to connect to each others network whenever you want.

    However the way you can do this but will require another piece of hardware is to get a third router (assuming you are able to see each others network wirelessly), use the third router to connect as a client to your buddies network and then use static routes to route the traffic for each others network to the third router.

    a computer as a third router?

    Yeah, that's my main problem.
    I have enough parts to setup a computer with linux, an Ethernet NIC (connected to my router) and a WLAN NIC (to connect to friends WLAN Router).
    Would I then be able set it up to route traffic between my network and my friend's network across the street?

    Yes if you can get an ip from across the street via wireless you can configure that linux box act as an intermediate router.
