Help with Sharing wireless, not WDS

    I have my D-Link DGL-4500 setup to work with my U-Verse router/modem. The modem/router is 192.168.1.something. The D-Link has an IP of and shares the wireless and everything. So everything connects through the D-Link with WPA/AES security. I want to expand my wireless and just using 2 WRT4G's with Tomato and WDS was pretty easy. But I really want the main router to be the DGL-4500, which does not support WDS unfortunately.

    Can someone help me with a way to share the wireless connection and bring it further through the house? I liked how WDS just used the same wireless network no matter where I was in the house and automatically switched. I have 2 WRT54-G's that I would like to setup in different areas. If you need more info on my network please ask as I am not sure how much more info is needed to set this thing up correctly.

    Consider using Ethernet-over-power adapters (200mbit/HD, not the cheap crap!) and connect the two routers together via LAN ports, which will give you the equivalent of a wired WDS bridge.

    Option 1 - Connect additional APs by wire
    Chan X               Chan X+5    Chan X-5      Chan X+1
    [] = optional
    - SSID, and security settings on MainRouter and all APs are exactly the same.
    - Channels are different.
    - DHCP server only on MainRouter.
    - Wired connections are from LAN port to LAN port.

    Option 2 - Connect additional APs by wireless
    If you cannot do WDS, you'll have to add 2 additional APs to extend the network once.
    Chan X                  Chan X     Chan X-5        Chan X-5        Chan X+5
    [] = optional
    - WCx = a router set up as a Wireless Client, aka WET, Wireless Ethernet Bridge, Wireless Client Bridge.
    - SSID, security settings, and channel on MainRouter and WC1 (wireless client 1) are the same.
    - SSID, and security settings on AP1 could be the same as MainRouter, but should preferably have a different SSID (as it's a new wireless network), but definitely a different channel.
    - DHCP server only on MainRouter.
    - Wired connections are from LAN port to LAN port.

    ok so i figured maybe its easier to just do WDS and setup more routers especially since you are even saying if I can't do WDS do this. So now i have it setup like this

    mainrouter ip, DHCP server, channel 6, SSID=MAINROUTER
    2nd router ip, no dhcp server, channel 6, SSID=2ND
    3rd router ip, no dhcp server, channel 6, SSID=2ND

    the 2nd router is plugged into the main router
    2nd and 3rd are both running tomato with WDS, WPA-AES, default gateway of

    so i have it like this and can only see the MAINROUTER network and not the other SSID. any tips on this? thanks again for the original help.

    that was odd, all i had to change was WDS to WDS+AP on the 2nd router and my laptop can go anywhere in the house or outside!!

    WDS only means the routers just talk to one another as WDS nodes - they don't talk to clients as they are not Access Points (APs). WDS+AP means they are WDS nodes, PLUS they talk to clients like an ordinary AP.

    Do I undestand correctly that you have:
    If so:
    MainRouter should be on channel 1 (or 11 - 5 channels different from the other)
    WDS+AP2 and WDS3 should be on the same channel (6 in your case).

    Your WDS3 is not doing anything in this scenario, as it is just a WDS node. If you get wireless coverage for your laptops everywhere you need it, it means you need only MainRouter and WDS+AP2.

    If, however, you want better coverage, also change WDS3 to AP+WDS.

    thanks i just noticed that last router won't let me connect. so AP+WDS for every new router I introduce into this? I might get one more so I can get a better range in the backyard. and the DHCP server is still whatever the mainrouter gives out, correct?

    Your best setup would be to have
    MainRouter(AP)--WIRED--WDS+AP2--wireLESS--WDS+AP3--wireLESS--(add more WDS+AP)
    but have

    MainRouter: DHCP server, SSID "Main" Chan 1
    WDS+AP2: DHCP server off, SSID "Main", Chan 6
    WDS+AP3: DHCP server off, SSID "Main", Chan 6

    and have all your wireless security settings on all 3 devices the same.

    This way, your clients will have ONE wireless network setup (that for SSID "Main" and its associated security settings), and it will
    connect to MainRouter when your laptop(s) is near MainRouter
    as you walk to the coverage area of WDS+AP2, your laptop will automatically connect to WDS+AP2
    as you walk to the coverage area of WDS+AP3, your laptop will automatically connect to WDS+AP3

    Just one caviat: If your laptop is connected via WDS+AP3 (and you usually won't know through which device your laptop is connected), your wireless speed will be half of what you could get if your laptop was connected to MainRouter or WDS+AP2. That is because WDS+AP3 has to repeat wireless signal. The trade-off you have to consider, is, without WDS+AP3, you may get a weak signal from WDS+AP2 (or from MainRouter), and your wireless connection speed is say 24 Mbps. On the other hand, if you have WDS+AP3, you may get 54Mbps connection speed, but your actual wireless transfer rate is halved.

    does the WDS+AP2 in this situation have to be plugged in since my mainrouter doesn't do WDS? I think I will try it out the way you just suggested and see how that works. Everything that needs speed in the house is hooked up with a cable. Otherwise its just trying to not run wires all over the place and be able to go in any room and just start working.
