    I need help optimizing my LAN


    I have a HTPC that I often transfer large files to. I've worked hard on making sure I have all the equipment to have a fast LAN, but for some reason Windows 7 is slowing it down. I've tried following directions all over the net and haven't had any luck. I'll post my equipment and the results of my experiments below.

    Equipment:

    • Desktop (W7/Ubuntu) - Ethernet 1gbps
    • MacBook Pro (OSX) -Ethernet or Wireless
    • HTPC (W7) - Wireless but can hook up gigabit Ethernet for testing
    • ASUS N56-U Gigabit Router (Latest firmware)
    • All ethernet cables are Cat-5e
    • No other 2.4Ghz equipment nearby.

    Tests:

    • Direct Ethernet from Desktop W7 to HTPC W7 - ~100 MBps
    • Same, but through router, - 3-10 MBps
    • Again through router but Desktop Ubuntu to HTPC W7 - 3-10 MBps
    • Macbook Pro to Ubuntu - 60MBps

    This tells me the router is working as transferring back and forth between Ubuntu/OSX works fine. However, when my Windows 7 HTPC gets involved it slows down significantly. ONLY if the router is involved though. Direct ethernet gave me 100 MBps. This makes me think it has to be a setting in Windows 7. I've spent dozens of hours trying to figure this out myself, but can not figure out anything.


    For the record, I am aware of differences in bits/bytes and they are correctly labeled in this post.

    I ran another experiment: Windows 7 to Macbook also gets 60MBps. So Sending isn't the issue, just recieving on the HTPC
