2 WRT54G Routers in 1 house... 1 network possible?

    I have an older WRT54G router that is connected to my cable modem. It's working fine.

    I just connected a brand new router to it (same model) and I want to place the new router in the other end of the house, to extend wireless signal and hardwired ports to devices in that end of the house.



    Everything pretty much works except devices on ROUTER1 can't see or interact with devices on router 2, and the only thing devices on router2 can do is access the firmware of ROUTER1, can't see other devices on ROUTER1.

    I'd like itunes music sharing to work across both, as well as shared network drives. I've tried putting ROUTER2 into ROUTER mode instead of gateway, but it all stops working when I do that. I've also tried turning off DHCP server on ROUTER2, but then wireless connections drop and can't be reconnected.

    Thoughts, instructions of linksys, just simply say to put ROUTER1 into subnet and then use as i have now.

    Connect the routers using the LAN ports (don't use the WAN port of router 2). On router 2 you can disable DHCP, the firewall and the WAN port. Basically you just want router 2 to be a switch and a AP. Also set router 2 to be in the same subnet as router 1.

    disable wan port? not sure where that option is, also should i change the router/gateway setting under advanced routing?

    You simply need to configure one of the routers as a WDS repeater. You cannot do this with the stock Linksys firmware - you need something like DD-WRT. Check the dd-wrt website www.dd-wrt.com in the WiKi for step by step instructions on how to set this up.

    I have a long ranch house and use this setup. I actually have 4 WRT54G's. One main router, one as a repeater and 2 as wireless bridges

    Bruck, when you connect the 2 routers, with ethernet cable, from lan port to lan port, it does not actually matter whether you disable or not the WAN port of RTR2 - it's not used in this setup. Similarly, it does not matter if your WRT is set to router or gateway. The router/gateway setting is used for interaction with the WAN port, and dis- or enables NAT.

    Putting RTR2 in the same subnet as RTR1 means you make RTR2's IP address something like, with subnet mask This way the 4 LAN ports of RTR2 (now only 3 not used) are just like extension ports for RTR1 for connecting wired clients. You don't - and should not - use the WAN port of RTR2.

    For the wireless, both RTRs need to run as APs only. You can/must have the same SSID on both, but DIFFERENT channels, like 1 and 6, or so. This way wireless clients can move (roam) among the coverage area of both routers.

    Be sure you have a DHCP server running only on ONE of the routers.

    Does it work with a WRT300n v2 (connected to Internet Modem with ethernet Cable) with original LinkSys Firmware and a WRT54G v2 with Hyperwrt Thibor15c?
    What should be the configurations for both devices?
    I would like to expand the Wireless signal at home using both routers connected wirelessly.

    thanks in advance

    I have version v3.0 WRT54G How do I enable AP? Do I need a different firmware to do this?

    No Naborneo, you don't need different firmware, you can use the stock or any other firmware. The default for a WRT54 is to be a wireless access point (AP), in addition to being a router.

    When used as described in post #5 (with 2 WRTs connected by wire), you use the WRT as a wired switch, and a wireless AP.

    Working great, switchs between both routers great and no big fuss getting it set up, thanks for the help everyone

    Make sure that the routers have well-separated channels so that the wireless signals do not interfere with one another. i.e. if the first is on 1, put the second on 6 or 13.

    If you can reach a cable to the second router from the first DO NOT USE WDS as it will halve your available bandwidth in order to form the backbone link. I have this very setup at my place, but the gateway router's (first router) wireless is turned off as it needs to be next to my cable modem to distribute, but I have a lot of cables around and therefore get a bad signal fro it. I turned off the wireless on the first router and plugged in the second router behind the first (it has DD-WRT on it), with DHCP turned off, but the wireless turned on. This gives me a much better signal (the second router is much higher up and clear of cables) and I also use it as a VPN endpoint.

    this is how I have eveything wired into each other...The only wireless access I use if my Powerbook, the 2 routers are wired into each other, and I haven't seen any significant slow downs...maybe a little on the upload but I think that is just from using the powerbook wirelessly.

    You don't actually need the switch before Router-2. The 4 LAN ports of the WRT IS a switch.

    And your little slowdown is definitely due to the wireless as opposed to wired. You should see virtually no wired slowdown with your setup.
