    Hi Guys,

    I think someone has asked a similar question to this but it's not quite the same...

    I have a multiple router setup at home which is working fine save for one problem, windows networking is not working between devices on two different routers. The catch is that I need to have DHCP enabled on both routers as I am using one for G-only wireless and the other for N-only wireless (for max throughput).

    DIR-655
    WAN - Dynamically allocated
    LAN: 192.168.0.1
    DHCP: 192.168.0.100-255
    LAN SUB: 255.255.255.0

    DI-524 WAN port connected to DIR-655 LAN port

    DI-524
    WAN - 192.168.0.100 (static from DIR-655)
    LAN: 192.168.1.1
    DHCP: 192.168.1.100-255
    LAN SUB: 255.255.255.0

    Is it possible to do this? Any help would be appreciated!

    Why do your need 2 routers in your house? If you comeputer on 192.168.0.0 nextwork can't ping 192.168.1.0 network, and I assume that there is no firwall between the network, it is a routing problem. You might need to add static route on your routers.

    Anyway, it is wrong from the beginning to have 2 routers on your home network. You need wireless access point instead.

    You'll need to have the same IP address for the 2 routers. You can do this by turning off the DHCP server on one of your router so the router becomes an access point.

    Then use a regular LAN cable to connect the 2 routers from their lan port.
    Lan -> Lan connection. Your router which has the DHCP server will assign ip address to your other router if you connect it this way. Then you can share whatever you want on the network without any conflict.

    jackluo923,

    Do you know if the DHCP server on the one router will assign addresses to computers connected wirelessly to the second router?

    Thanks for your help.

    If you set it up correctly, then it will.

    Don't run both as a DHCP server. It just gets confusing.

    Depending on which routers you've got (Yes, I see what you have, but I'm not familiar with how good they are, I'm a Linksys kind of guy), and their firmware capabilities, I would probably run it like this:
    ISP/WAN ---> N Router ---> G Router, using the G router as a DHCP forwarder.

    I've got a ton of Linksys stuff routed through my place running DD-WRT, and we only have on DHCP server for all 13 computers, 6 routers + the various other devices.

    Thanks for everyone's help. I would've responded sooner but last night my windows network decided to stop working properly. All computers lost the ability to resolve another computer's name to an IP. Anyways, I got that resolved this morning and my network is set up properly now!

    The DIR-655 (N router) is acting as DHCP server for all devices. For some reason, I had it in my head that the DHCP on the N router wouldn't assign addresses to anything connected wirelessly to the G. I think I was too close to it...

    Anyways, now I'm adding another 1.5TB of NAS! Sweet...

    Thanks again. +1 all around.

    Just FYI, you stated your problem right in this post. The netmask was preventing you from connecting between the machines... 255.255.255.0 means that the first 3 bytes have to match to connect to it. 192.168.1 and 192.168.0 are different, so you can't connect with a 255.255.255.0 netmask. You'd have to use a 255.255.0.0 mask. But your single router being a DHCP server is a better solution... just figured I'd shed some light on the original cause of the problem ;)
