Random Disconnects from Internet

    I have a desktop PC in one room connected to the modem by Ethernet and a
    laptop in another room connected to the modem by wireless. Deskop is running
    XP SP3 and laptop is running Windows 7 Pro, both fully updated.

    I mostly work on the laptop but keep a Remote Desktop link open to the PC so
    I can swap backwards and forwards between the laptop and the PC.

    At random intervals, the PC loses its connection to the Internet and I have
    to run repair on the local connection to get it back.

    I know it's not a modem/ISP issue because the Internet connection is still
    live on the laptop; it's also not an IP address issue as the PC is holding
    its IP address because the Remote Desktop link is still working, also I can
    see the IP address when I run IPconfig on the PC. The IP address is set
    manually on the local connector, by the way, not DHCP.

    Any ideas, anyone?

    What exactly is this 'modem'? It must be also a router, some kind of
    gateway device. I presume it is giving out translated IP addresses to
    both the DT and LT, or what?

    When you say the DT is keeping its IP address, you must mean it is
    keeping its translated IP address from the gateway device but it isn't
    getting on the internet.

    I think we should start with the brand name and modelno of this modem
    (and networking device) so that we can get a picture of the topology of
    the network.

    It's a Netopia 3347NWG router.
    All my PC's have manually assigned IP's in the tange 192.168.1.xxx with
    Gateway set to, the address of the router.
    It's getting on the Internet, it just drops the connection to the router at
    random intervals.

    So it's a problem with one computer then. Try these on both computers:
    1. right click my computer, left click properties and then click on the tab
    marked performance. What are the numbers for system resources on both
    computers? Do this with *nothing* running - no browser, wordprocessor or
    anything else.

    2. right click network and left click properties. Post a listing of or what
    is different between the entries there. You should have only your internet
    device and tcp/ip. Nothing else.

    That is the default configuration of the 3000 series.

    http://www.netopia.com/support/hardware/technotes/CQG_121.html - Browse
    into the Netopia's web interface at (if using the
    default IP setting)
    No, I meant, you said...
    But then you also said:
    So, I was saying that you had said that (under the condition of losing
    its connection to the internet as you said) that you could see on
    IPconfig that the DT had its 192.xx address. But you are also saying
    that you have it configured for/ to be/ that address, which is different
    from getting (being assigned by the router) that IP address - getting
    any 192.xx assigned to it from the router.

    I think we need to talk about how you have the router configured to deal
    with giving the DT (desktop) a specific IP based on its MAC address, and
    I also think we have to talk about how you are dealing with the VPN
    (which your remote desktop setup is) inside the router.

    We can't see the router's configuration pages from here, so you will
    have to describe all (some of) that.

    Another consideration to think about is that when routers are 'acting
    up' unpredictably and it is determined to not be due such as your own
    configuration errors or such as having the LAN arranged/wired 'stupidly'
    such as having disconnected/unterminated ethernet wires hanging off LAN
    ports, or some other undiagnosed factor which is not the router's fault,
    that is 'outside' the router's responsibility -- then sometimes it is
    necessary to flash a router's firmware to fix it.

    Firmware flashing is not a decision to be taken lightly, especially the
    way Netopia handles the firmware issue. From what I'm reading, they
    make that subject complicated.

    Subject: Why you hard boot your DSL modem
    Date: Sat, 11 Mar 2006 02:42:16 -0500
    From: "Steve" <>
    Organization: Smell Sympattycake

    There's been some questions and confusion in a previous post in regards to
    why you "hard boot" (or "power drains" as chuck likes to call it) your DSL
    modem. I'm compiling a website for these NG's to cut down on the utter
    bullshit that's been posted in here by some posters (*caugh* chuck). So
    lets clear out the bullshit and get back to business. This took me 30 mins
    to compile and write. This is for those who wanted to know exactly why you
    turn your modem on and off, and why this works.

    Power cycling your modem or hard booting your modem, by completely
    unplugging it for about 30 - 40 seconds then turn it back on again, can fix
    some internet connection problems. Here is a more in-depth response to this
    issue as to why this is done.

    This clears out your modems buffers which can get over filled due to Packet
    Loss; and this intern can cause your modem to loose sync with the
    connection. This is the most common problem that causes loss of sync with
    your connection and power cycling your modem is used to re-sync it. However
    this is a quick fix to this problem. In most cases this can be prevented by
    having the appropriate network tweaks and settings in place, which is
    something that the tech turnips at Sympatico should be informing us on.
