    Hi folks,

    no results found on search. So my question is:

    I've got a D-Link 655 running (single band) and I wonder if there will be performance improvements when I switch my router to a dual band like D-Link 855/825 or to Airport Extreme.

    My current results with the D-Link 655 are:
    MacBook 2,1 => 3-4MB/s
    MacBookPro 5,1 => 5-6MB/s

    So with the (new) Airport Extreme it is possible to use both bands (2,4GHz & 5 GHz). What are your average transfer speed?

    Thx, jazer

    How did you do the measurements? I just installed a new Dual Band Extreme and I can measure performance, but I would prefer to use the same method for testing that you used.

    Thanks for reply,

    I haven't use any sophisticated benchmark tools. Just used iStats Menu 2.x and copied some GB's of files to my NAS (which makes about 25MB/s), which is connected with my Router over Gigabit LAN. So its just an estimation.

    Thx

    Okay, here are my highly unscientific results ... my configurations were:

    All tests on 5Ghz "n" with wide channels enabled

    Config #1:
    750GB USB drive plugged into a dual band Airport Extreme
    Apple Mini plugged into a Gigi Switch, plugged into an Airport Express "n", the Express was configured as a ProxySTA mode attached to the 5Ghz "n" network

    Config #2
    750GB USB drive plugged into a dual band Airport Extreme
    Apple Mini plugged into a 1T Time Capsule extending the 5Ghz network

    Config #3
    750GB USB drive plugged into a dual band Airport Extreme
    Early 2008 17" MacBook Pro connected to the 5Ghz "extended" network.

    Test procedure:

    1. Browse to the USB drive hanging off the Dual Band extreme
    2. Copy a 5GB movie file (m4v) from the USB drive to the local desktop
    3. Observe the "in" network reading on iStat Pro Widget

    Throughput:

    Config #1: 3.6MB/s
    Config #2: 10.4MB/s
    Config #3: 5MB/s

    I also tried Config #2, but using the MBP instead of the mini and got similar speeds. The Airport utility reports the "rate" from the TC @ 216. Previously with the Express, the rate was reported as 162. So, I am concluding that the TC is doing a better job than the Express at throughput on the 5Ghz network.

    I don't know if this helps or not ... I think your config is closer to #3 and I am guessing that you will not see any significant change in throughput if you switched network devices. I use the Express + Gig switch and now the TC as a way to wire all the stuff in my home office together at Gig speeds for file sharing/printer sharing, while providing access to the rest of the world via wireless. I am very pleased with the speed up from the Express to the TC. I am also glad to get rid of the Gig switch because it was periodically going wacko and required a power cycle.

    Good luck ...

    Thanks a lot. This helps much for me.

    You are right - config #3 is the most comparable.

    Great work!

    Thx,
