    Hi Folks,

    i just want to ask, whether someboday already has experiences with connecting 3
    WRT's via WDS wireless relay. According to some wiki i have found, the perfomance
    should not be affected. Wirless bridging on the other will decrease the data rate, so
    a pure wirless-n-network will not make much sense. Am i right ?

    Thanks and Cheers

    Tim

    Hi HennieM,

    thanks for the information. very good investigation of the basics ! but i guess time-consuming :)
    on the other hand it does not really answer my question...by the way why did you use
    only for the first WRT dd-wrt ?

    Thanks

    Tim

    Tomato is slightly faster than DD-WRT, but I had DD-WRT on that specific router, and it was a bit inaccessible, so I left that router as is and connected to the wired net. I was looking at relative speeds only, so the exact speed did not matter at the time.

    Now then, in turn, I don't understand your question..., but the bottom line is this:
    For every single 54G radio repeater in a chain, that device must 1st receive radio signal at half duplex (one way), and then transmit radio signal at half duplex. Therefore, every single radio repeater in the chain takes your speed down a notch.

    If you have 3 WDS devices in a chain, your performance would certainly be down, WHEN THOSE WDS DEVICES HAVE TO REPEAT A SIGNAL. If those same devices don't have to repeat, you will get full wireless speed through them.

    Wireless bridging, like this

    ---wired---Bridge---wireless---Bridge---wired---

    or like this

    ---wired---WDS---wireless---WDS---wired---

    will give you full wireless speed through the bridge/WDS link, as none of the wireless bridge/WDS devices have to repeat a wireless signal.

    (The WDS link would be marginally slower that the Bridge link because of the WDS overhead, but not so as you'd notice).

    However, if you mean performance relative to _wired_ speeds, then yes, any 54G bridge/WDS will impact on the performance.

    An N-link (where the bridges or WDS nodes are running draft-N with channel bonding and all the N-stuff working), would impact less, or maybe not at all, on the _wired_ speed.

    Maybe post the link to that Wiki so I can have a look-see.
