laughable 10 kb/s transfer speed on home network

    Hi guys,

    I've spent couple of hours setting up my home network. When I finally managed to get it to work, as in the computers could finally detect each other, I realized my happiness was shortlived. Download speed for the internet was blazing fast at about 300+kb/s, but when I try to transfer files within the network, it only managed a laughable 10kb/s. I mean I had way higher expectation than that! I expected the transfer speed to be about 9MB/s for within the home network coz I am not limited by ISP's speed limit. What happened here?!:confused:

    Perhaps it is useful if I provide the setup.

    Windows XP SP2 Desktop PC
    Windows Vista SP1 Laptop
    WRT54GS router
    TimeWarner Roadrunner 3mbps Cable Internet

    Now I know it might be hard hard to troubleshoot this with the info that I've provided, so if you need further info from me, please let me know. I really need to solve this problem. Thanks in advance everyone!

    Few questions:
    Do all your machines get 300+k on Roadrunner or did you just test one?

    How did you measure your speed between your lan computers? Windows doesn't normally show speed in Kb/s in file xfers.

    Are you using stock Linksys firmware? Do you have any QOS enabled?

    Hi there,

    I managed to get to about 250kbps between my computer by trial and error.
    Is this normal, considering I'm using Wireless B instead of G?
    It'll be sweet if I can get it up to over 2mbps.

    And I am using Windows Vista which shows me the speed of transfer.
    For my Windows XP, I did the calculation manually.

    I am using stock Linksys firmware.
    I have no idea what this QOS thing is. I am going to ask my best friend, Google, now.

    Well wireless B with no overhead under ideal perfect conditions will give you 11 mbits theoretically, however you probably won't see much over 5... so around 600-800k/s is what you should see... however wireless can be real flakey and easily drop down, also if your router is in mixed mode it will decrease preformance even more..
    Try it wired if you can to eliminate any WIFI issues.

    Vista (and XP) sometimes install additional drivers, usually called "QoS something", on the network adapters. Disable or uninstall those, and see if that helps.

    Vista could also be trying to do fancy stuff on the network (something like dynamic scaling or some fancy name) which can make things go slow.

    Make sure all your computers are in the same workgroup or domain. Working across workgroups can also slow things down.

    Finally, I think Guyfromhe is generous - on an 11Mbps connection I think you would get MAX 600kBps (about 4.8Mbps).

    As I stated: "wireless B with no overhead under ideal perfect conditions will give you 11 mbits theoretically"

    Words to note: With no overhead, indeal perfect conditions and theoretically
    I then continued to say that they would get 600-800k max if you read what I posted :p

    Wireless is also half-duplex, can't send and receive at the same time so wireless to wireless via router is at least half again, compared with wireless to/from wired.

    @Guyfromhe: No PUN or disrespect intended! I was giving my opinion (which, most of the time, is not accurate....)
