    Hi Folks,

    I have 2 Linksys WRT54GL units running Tomato firmware
    Each Router has its own ISP (1 cable and 1 DSL)
    Each router has a unique IP addy and the same subnet
    Some workstations are connected to router A and some to router B
    All wired workstations have unique static IP addys
    Both routers are handing out DHCP but in unique ranges
    DHCP is only for wireless devices
    Each routers wireless is on different SSID
    All is working well but workstations on different routers cannot see each other, nor can they get to the other ISP
    I would like to connect both routers for the following purposes
    1 - single workgroup with file and printer sharing
    2 - ISP failover (I am prepared to make the manual change to the network connection in the workstations)
    3 - ISP manual selection in order to take advantage of ISP limits, caps etc.

    I don't see a problem in accomplishing this with a wired connection between the 2 routers however running a cable is not possible.

    Is there a way to utilize the wireless to connect the 2 routers?
    ethernet bridge mode kills one of the ISPs so that will not work
    If its any help, all wireless devices could connect through a single router

    Load balancing is not a requirement
    The cable running problem prevents me from co-locating the routers. DSL is delivered to one area with no coax from the cable provider and vice versa

    Systems on one WLAN (SSID) can't see systems on the other WLAN (SSID) by design. If you want to join the two networks together, you should have a single WLAN. A single network.

    The closest you could come with your current setup is to stick a 2nd wireless NIC in each system and use that 2nd NIC to attach to the other network.

    Thanks for your reply Monk....understood
    Different SSID is not actually a requirement here...I could live with a single SSID for the wireless devices
    Would there be any opportunity to utilize something like WDS to accomplish the goals?
