Losing Connectivity to NAS200

    I have gone through the forums and looked at the various threads and posts and I have not seen an answer to this problem. I lose connectivity with the NAS200 from one (and only one) of the PCs on my network. Here is the setup:

    4 PCs on the network
    2 running Win 7 Pro SP1
    1 Running Vista Business SP2
    1 Running Windows Server 2003 Enterprise SP2
    With firmware V3.4R79
    2 – 500 GB drives run as a RAID 1 (Mirroring)
    Set to go to Standby after being idle 30 minutes (the only other option I have is to go to Standby after being idle 10 minutes)

    All are fixed IP.

    The Windows Server, Vista and one of the Win 7 machines experience no problems with the NAS200. However, one Win 7 machine loses connectivity after 30 minutes of so. I have seen similar problems referenced in the forum but unfortunately no solution.

    After a boot, the problem PC has full access to all of the files. However, after 30 minutes or so the files on the NAS200 are no longer available via Windows Explorer or individual applications. The files are available during this time via the web interface ( To restore file access via Windows Explorer or an application I have to reboot.

    I have reinstalled the firmware (same version V3.4R79) which has not fixed the problem. I am unable to reset the network settings on the NAS200 using the reset button (held for 2 or 3 seconds) although I am able to reset the password on the NAS200 by holding the reset button for 10 seconds or so. I can reset the network setting via the web access, however.

    Any ideas what might be causing this problem? Thanks in advance.

    The Solution Is

    I have kept plugging away at this, trying different things (e.g. disabling the firewall, etc.). I found that I did not lose connectivity when I disabled the sleep mode on the problem machine. So I disabled the "Allow the computer to turn off this device to save power" on the Power tab for the NIC in Device Manager. This appears to have solved the problem.

    I don't understand why this works. My other Win 7 machine which was not exhibiting the loss of connectivity problem has this feature enabled.

    The Above Helped, but

    I also had to replace the Microsoft Win 7 NIC driver with the manufacturer's driver (Broadcom). I am now up to 24 hours without losing connectivity.
