Hyperwrt with WDS and QoS

    Hi I am using HyperWRT Thibor version and everything is working well, except after I added 2 new nodes to the network.

    I had 2 nodes connected to my node via WDS with my node being the gateway. Everything is fine and network speeds acceptable.

    I added 2 new nodes where 1 of them connects to my node and the other one connects to one of the other nodes also via WDS. However there is a significant drop in speed for only those 2 nodes. Anyone has any ideas?

    I also setup QoS on each router where I set my torrent application ports to the lowest priority however it doesnt seem to work. My Torrents continue to eat up bandwidth without giving the priroity applications protocols like HTTP preferance.

    thanks for any info giving

    firstly you need to be a little clearer with your description; describing both wireless clients, the main router and wds mode routers as "nodes" is a little confusing. i think you are saying that wireless clients connecting through the wds "nodes" are slower than if they connect via the main ap. this is what will happen and is not a fault condition. you also don't use QoS on any device other than the Gateway, it is performed on outgoing traffic to the internet.

    RE: WDS and QoS

    ROUTER 1 = MAIN AP with Internat Gateway

    ROUTER 2 and 3 is connected vis WDS to ROUTER 1 with no problems in

    The new node called ROUTER 4 is connected again to ROUTER 1 via WDS
    The second new node ROUTER 5 is connected via WDS to ROUTER 2.

    Both ROUTER 4 and 5 have performance issues.
    I understand why ROUTER 5 will be slower as its bandwidth would be 1/4
    of the orginal 54MBPS ?

    Is there any tweaks you can do improve ROUTER 5 and 4?

    unless you are deliberately extending the wireless range, you could try WET(wireess bridge) or STA(client mode) instead. the disadvantage is that wireless clients will not be able to connect but your bandwidth may be better. i have 4 wireless nodes using wds here and haven't noticed any performance issues. maybe try replacing the antenna for a higher gain if there is a connectivity issue.

    you have to understand that using WDS effectively cut your bandwidth into half. Remember that wireless is a half duplex system unlike Ethernet which is full duplex.

    I have 3 routers using WDS:

    #1 Main
    #2 connected to #1 via WDS
    #3 connected to #1 via WDS
    NAS and Servers connected to the switch on #1

    Granted, I am not trying to extend my range further by for example, connected #3 to #2, but I can stream HD from my HDHomeRun to any wireless client (connected to any of the Linksys's) and get great results. Of course, I always have an excellent wireless connection at the client.

    I would suspect I would not get my results if I was connected to a Linksys that was connected via WDS to #2 or #3. Also, using WPA vs WEP made a difference for me.

    With my config, I have great/excellent wireless coverage for my clients in my property.
