    I have a 2009 MBP with OSX Lion installed. It's in dual boot config. with Win 7 installed in second partition, primarily for office work.

    Recently I added IOMEGA Home drive Cloud edition to my home LAN to act as central storage for all Mac and windows systems at home. It is wired directly to my Linksys WRT54GL Wifi Router.

    Issue I am seeing is that even on a wired connection, the transfer speed from Macbook to/from NAS drive never goes above 2.5 MByte/s. When I dual boot my macbook in Win7, I get 7.5-10MBytes/Sec.
    Even other Windows systems constantly get over 10 MBytes/sec when wired.

    Any idea as to why OSX is giving such low transfer speeds and any suggestions to fix it?

    1. IOMega home drive is slow
    2. 100MB networking is slow
    3. also G WiFi is slow

    Get a Gigabit switch or a simultaneous dual band Gigabit router

    You say the Macbook is hardwired. Is it also connected by wireless? If so, when multiple network connections are made OS X defaults to the top connection listed in the Network pane of System Preferences. Turn off airport on the Macbook while hardwired.

    In the left-hand column of Network preferences pane, where it lists Ethernet, Airport, etc., click the gear icon below the list, and choose "Set Service Order...".

    A sheet drops down, and you can drag the services so Ethernet is at the top. Click "OK".
