maximum bandwidth through wireless

    hi

    i have a connection rated at 10mbits /sec downlink and 640 kbits/sec uplink.

    when i'm directly connected to the cable modem that i have, i average about 7500 kbits /sec. when i'm directly connected to the router (wrt54gs) i get about the same.

    however, when i try to do this through wireless, even with a laptop beside the router (or even within a few meters of the router), i only get about 5000 max and about 3000 - 4000 kbits/sec maximum bandwidth while the upload bandwidth is about the same as connected directly.

    is wireless really that much slower or is something wrong? i'm assuming that a connection thats at 54mbits/sec through wireless should get atleast 27 mbits per/sec because its half duplex which would mean that i should get the same as when i'm directly connected.

    is there a maximum wireless bandwidth that is known for the wrt54gs? or is something wrong.

    thanks.

    I get very similar results either using a wired or wireless client on the Speakeasy Speed Test. Perhaps you have issues with your wireless? (interference, client configuration, etc.)

    yea i'm thinking interference. theres quite a few AP's around me. but i thought maybe being right bseside the router would helpa bit.

    This is my WRT54GL+Tomato 0.7 mini test.
    I hope it would show you something.

    Hello,
    I have to test the throughput too.
    Wich tool made these nice graphs? Can you give me a hint?
    Thanks

    dankim831, is your Frame burst and Speedbooster on on the WRT54GS, and in your card/adapter's driver?

    27 Mbps is really idealistic, as part of bandwidth is used to make sure the signal get from one side to the other. However, with Speedbooster/Afterburner, and (most impact IMO) Frame burst, you can exceed 27 Mbps under ideal conditions.

    Perhaps time a file transfer from a wired to wireless computer, and the other way round, which takes the speed of the routing/internet out of the equation, and will give you a better idea of your wireless speed.
