Client mode vs WDS

    I'm trying to setup two routers and have it working fine with WDS. However I'd like to see if I can set them up to do Client Wireless mode. I do some media streaming and would rather have the full bandwidth that WDS chokes.

    But I can't get it to work with Client mode. I watched the video on polar's site but still don't quite understand.

    How do I setup the router connected to the web, as just access point?

    With WDS I understand the ssid being the same, is that the case with client mode?

    And does the client have to be a different ip?

    Is there a way to use wireless client mode to cover an entire area and use the same ip's?

    In client mode your router is going to act just like a wireless card in your machine does. Client mode is "bridging" the connection for you, so you will have to connect your clients to the router via a cable. You will also need to make sure the subnets are different (different ip ranges) on either side of the router.

    if you want to stay wireless you could also set up a roaming wireless network, the only real catch with that is all wireless routers needs to have a cable connection to each other.

    The devices connected to router 2 are connected via wired.

    How do I use router 2 as a wireless connection to router 1?

    Wireless bridge? I am not sure of the right term.

    The only way to keep IP's the same is WDS?

    Have it working using wireless bridge mode on router 2 and regualr AP for router 1. WPA Personal with AES on both, same SSID, same IP address subnet. Seems a little faster than WDS mode. So we can roam around the house with the laptops and stay with same IP addresses and I can connect my Toshiba HD-DVD and Wii through router 2.

    Probably still need to tweak some stuff.

    In this scenario WDS will provide the same bandwidth as
    "wireless bridge" oder "client" mode, so I'd suggest you
    stay with WDS.

    Will look at going back to WDS. I would like to limit which wireless devices, laptops, connect to a particular router. Tried with MAC filtering this morning. I tried setting router 1 up to only allow wireless from router 2 and turned on dhcp server in router 2, while I could access the routers, I could not get through to internet/wan. Feels like a configuration problem.

    Thinking I would need seperate SSID's, etc., but not sure.

    Tried WDS again. It is noticably slower than ethernet bridge mode. Not sure why but it is.

    MAC filtering works fine for what you want. No need for separate SSIDs. You should only have one DHCP server enabled, and that should (generally) be on your router connected to WAN. Your statement "tried setting router 1 up to only allow wireless from router 2" makes me think that you entered the MAC address of router 2 in 1's MAC Filtering section. That is not the way to do it. You should enter the MAC addresses of the wireless clients you don't want to be able to associate with router 2 in its MAC filtering table and set it to block those. Or, you can list only those you want to be able to associate with each and set it to allow only those.

    I am trying to limit the laptops that connect to router 1.

    Router 1 is the wan connected router.

    I was hoping to force laptops in use in the front room to connect to the router with the entertainment center, router 2, which is also in the front room.

    Both routers are showing the laptops in their respective device list as if we are connecting to both routers.

    Set Router 1's MAC Filtering to block the MAC addresses of the laptops in the front room. That should work. Alternatively, if you never want any clients to associate with Router 1, then set it to WDS Only instead of WDS+AP.

    Tried that but router 1 being the dhcp server meant any MAC blocked laptops didn't get IP/DNS, etc.

    So set router 1 to WDS only, turn on DHCP for router 2?


    And I don't want to limit router 1 to no laptops. I'm just trying to get the laptops closest to router 2 to only use router 2.

    I've just reconfigured my setup from WDS to AP+client ethernet bridge.

    Since I no longer used the secondary router for connecting wireless clients to, this works just as good.

    Are there any advantages to sticking with WDS?

    My setup is:

    internet <--> wrt54gl with two cable clients and several wireless ones
    on another floor: wrt54g (as a client to the first router) with two cable clients, no wireless ones

    I found that ethernet bridge setup was faster than WDS even in my limited application.

    WDS slower

    from the wikipedia entry on WDS

    Wireless throughput is cut approximately in half for each WDS repeating "hop", i.e. an AP that data flows through before hitting the wired network. This is because all transmissions use the same channel and radio and must be retransmitted to reach the wired LAN.

    other disadvantages of WDS

    Dynamically assigned and rotated encryption keys are usually not supported in a WDS connection. This means that dynamic Wi-Fi Protected Access (WPA) and other dynamic key assignment technology in most cases can not be used, though WPA using pre-shared keys is possible. This is due to the lack of standardisation in this field, which will hopefully be resolved with the upcoming 802.11s standard. As a result only static WEP or WPA keys may be used in a WDS connection, including any STAs that associate to a WDS repeating AP.

    I thought I'd play again just to be sure. Went back to WDS and observed "speed" of connection, web pages loading, etc. All very subjective I know. It really was noticably slower than WET mode. I know with my simple setup, 2 routers, it really should not be noticably slower. But it is.
