    Hello guys I built a HTPC/File Server/Backups repository and I'm transferring all the medias on my laptop to it but my speeds are simply abyssmal: I peak at 1MB/s. I uninstalled Windows 7 Pro and put vista business on the htpc to try to see if that made a difference to no avail. I then installed Ubuntu and the speed were still crappy, then I tried to transfer files from my mac to the htpc under ubuntu and the speed were much better about 8-10MB/s, but tring to transfer from my W7 machine to the Ubuntu HTPC still yielded garbage transfer speeds... :( I wan't to reinstall W7 on the HTPC because ATI drivers under Linux for video playback are not up to snuff compared to what Nvidia has to offer...
    Can anyone help me? what do I need to disable on Windows to make the file transfer bearable?

    Same behavior when wired and wireless. And the router is a Linksys WRT160N running DD-WRT. I know that the router is not at fault since transferring files under OSX and Ubuntu gives decent speeds. It's a Windows issue.

    that's weird, i didn't have any such issues with a standard install of W7 Pro x32 and x64 (desktop and laptop) using the WRT160N with DD-WRT.

    Transfer speeds were around 6MB/sec which is decent given that there is always at least 1 G device on the network active.

    however, I only use standard windows shares and not Linux/Mac.

    have you tried comparing 2 windows machines transferring files between?
    Using the WRT610N, now I have 9-12MB/sec movement on 5Ghz. 2.4Ghz G still gives the normal 2-3MB/sec transfers.

    It could be your Antivirus program causing this. You could try disabling real-time protection. From the transfer rates you mention it almost sounds like you are getting 10BaseT speeds on your wired connection and perhaps wireless-B speeds on your wireless. Try upgrading your network card's drivers and make sure that you are getting the right speeds on both the wired and wireless connections. Try forcing the wired NIC to connect at 100Mbps Full duplex instead of Auto Negotiation and see what happens.

    Yes here are the tests I did:
    W7 Pro(Laptop) - W7 Pro(Desktop) : 1MB/s
    W7 Pro(Laptop) - Ubuntu Lucid(Desktop) : 1MB/s
    W7 Pro(Laptop) - W Vista Business(Desktop) : 1MB/s
    OSX Snow Leopard(Desktop) - Ubuntu Lucid(Desktop): 5-8MB/s
    Ubuntu Lucid(Laptop) - Ubuntu Lucid(Desktop): 5-8MB/s

    I did those test when both wired and wireless on the desktop(802.11n pci card) and the result were the same. And I also had timeouts problems when trying to transfer through OSX and Vista Business.
