Couple of WDS questions

    I've read the FAQ: How do I use WDS?
    But I have a few questions still. I am planning on setting up a 3 router WDS.
    1. Can the link be via ethernet?
      - For example can I like Router #1 with Router #2 & #3 via Cat6 cable, or does WDS need to be a wireless link from one Router to another?
    2. Do all 3 routers need to be on the same "Channel"?
      - Is this correct, won't that degrade the signal from one another because they are all competing on the same channel?
    3. Bandwidth is halved on a WDS system?

    1. WDS stands for Wireless Distribution System (hope that answers your question)
    you can however, opt for cable connections and skip WDS altogether (setting up router 2 and 3 as wireless access points)
    2. not sure abt this >_<
    3. and yes bandwidth is theoretically halved cuz router 2 has to receive and transmit in both directions (towards router 1 and 3). double traffic = half bandwidth :p (non-issue with 2 and 3 running as wireless aps)

    Thanks azeari,

    That does clear things up a bit.
    So if I wanted to setup multiple routers all acting as their own AP (since I will have Cat6 cable running throughout the building) instead of WDS, can I still set them up as the same SSID so that if I am using a laptop that roams throughout the building it will grab onto the strongest signal depending on where in the building it is?

    Yes, that's the idea. Now you aren't using WDS you can separate the channels too. Be aware that Windows XP's Zero Configuration Service can screw that up for you, google for info.

    If you use WDS with 3 transmitters, you'll see a huge delay in response compared to the cable. Use Apple Safari or Google Chrome for an almost instant response from your router.

    How does this work if I was sitting in a room and the laptop keeps getting a higher signal every 5 minutes from each router? For some reason the main router on the network has a signal that constantly goes up and down.

    Great, so I set up all 3 routers (connected via ethernet) as AP's using the same SSID, So would I be better off leaving it on the same channel (so as not to screw with XP's Zero Config)? or does it not matter?

    No, put them all on different channels, 5 channel numbers apart (1, 6, 11) or they will unnecessarily interfere with each other.

    travanx: If all SSID's are the same then you probably would never notice anything although the PC may be switching between routers. There is a threshold under which the router will change channel, look under the settings of your wireless card. But do google "Wireless Zero Configuration" if you get any weird problems...

    Thank you. This is the first time I finally got this type of setup working. D-Link router is off the DSL modem on u-verse. The linksys is plugged in through the ethernet on the other side of the house (thankfully I had the u-verse guys run one ethernet wire over to that side). So D-Link is SSID on Channel 6 in the front and Linksys is SSID on Channel 11 in the back. Now I am going to attempt WDS for the backyard between my 2 linksys routers. The best part is I still have my D-Link DGL-4300 handling everything. Awesome! Thanks again. This is a big deal to me since I want to work out by the pool when the sun is out. =)
