    I have an internet connection problem, and must tell you that I know
    very little about this technology. In other words, anyone kind enough
    to help me out, please keep it simple.

    DSL connection.
    Router: D-Link DI-713P
    Desktop and the laptops all run Windows XP.
    The laptops have DWL-650+ wireless cards. There is no problem with
    The problem is with the desktop Dell Dimension 4700. It is connected
    directly to the router.

    The Windows device manager shows under network adapters: Intel Pro
    /100 network connection. It tells me that it is working correctly.

    This is the problem:
    Everything worked fine for months. Then, I noticed there was no
    internet connection after I booted the machine. After a while, there
    would be an intermittent and very slow connection. Now, there is
    When I ping I get the message that the host is

    When I do an ipconfig /release, there is nothing in the
    connection-specific DNS field. The IP address and subnet mask are both

    When I do ipconfig /renew I get the message that an error occurred
    while renewing local interface connection: unable to contact your DHCP

    Ipconfig /all shows:
    node type: unknown
    IP routing enabled: no
    WINS proxy enabled: no
    Connection-specific DNS suffix: blank
    Description: Intel Pro /100 VE Network Connection
    Physical address: 00-11-11-9E-7B-06
    Dhcp enabled: yes
    Autoconfiguration enabled: yes
    Autoconfiguration IP address:
    Subnet mask:
    Default gateway: blank

    Is there a way I can tell if the problem is with the router or the
    integrated network card?
    If there is a problem with the router, is there anything I can do
    short of replacing it?
    If not, can you recommend a DSL router that is compatible with the
    DWL-650+ wireless cards?

    Let me know if you need any other info.
    Thank you anyone who can help me with this.

    I assume it is similar to Linksys?
    What do you get with ?
    To me it looks like it has been reset or something?
    The first thing you need to do is to connect either a laptop or the desktop
    directly to the router & go through the setup on that first. If you can't
    get into the setup page then you must have a problem with either the Cat5
    cable or the network card. (or it's driver).

    When you double click on your wireless conection in the system tray and goto
    the support tab, what is the addres of your default gateway?

    Soenda Guest gets me the same result: unreachable.

    I cannot get to the setup page on my desktop.
    I can only do it on my laptop that has the wireless card.

    Looking over your origional post it shows when you did a ipconfig /all that
    you have a ip address of and a subnet of This
    is not being given by your router. Manuall change your ip address to
    something like with a subnet of and tell me if
    that gets your connection back.

  7. Start with the simple and the cheap:
    (1) power-cycle the router;
    (2) try different Ethernet ports on the router;
    (3) replace the Ethernet cable.

    your problem is that the internal network card on the DELL is not
    getting an IP from the router. the is the microsoft
    fallback IP ... this is the best indication that it doesn't have an

    do this, do a disable and enable on the network card on the DELL
    (right click on the lan connection, the disable. the enable.)
    see if this does it. If not put an ip into the fixed section fo the
    TCP-ip connection within the subnet of the router. Then reboot the
    computer and see if you can connect.

    If you can , then go back to the DHCP assigned IP an see if it will
    assign an ip to the card

    IF it won't , then do a 'un-install' of the card from the device
    manager, reboot and then let XP find the card and reinstall the
    drivers. If this works you problably had a corrupted TCP=IP stack and
    it will be rebuilt by doing the above.

    hope this works, I see this all the time with dells,,

    I may have made a little bit of progress.
    I did disable/enable. That did not do anything. Windows told me it was
    "acquiring a network address, Firewalled." A while later I go the
    message: Limited or no connectivity, Firewalled.

    Next, I did a repair. Windows told me it was renewing the IP address.
    Then I got the message that it was unable to do so.

    I followed your suggestion and manually typed in IP address: It provided the subnet address
    I rebooted and was still unable to get anywhere in my browser.

    However, now when I ping, I can send and receive packets without
    losing any. I guess that is progress.
    When I do an ipconfig /all I see that dhcp is not enabled. That
    probably makes sense to you. It does not to me, because I do not
    really understand what I am doing.

    I am not sure how you would like me to proceed from here. I know you
    mentioned going back to the DHCP assigned IP. I am not sure I
    understand this. I do know how to do an uninstall of the card from the
    device manager.

    Thanks for your help.

    When I manually typed in IP address:, Windows provided the
    subnet address
    I rebooted and was still unable to make an internet connection.
    However, I can ping, and send and receive packets without losing any.
    I was not able to do that before. I do not know what that tells me.
    though. For what it is worth,when I do an ipconfig /all I see that
    dhcp is not enabled.

  12. There seems to be something wrong with DHCP requests. Was your computer
    initially set to obtaining its IP address (etc.) through DHCP? In any case,
    if you manually provide the IP address (as you have; btw: is it or, then you also have to provide the addresses
    of DNS servers. You can find those on the computers that currently work
    when connected to the router.

    I would also try the following: Use device manager (start->settings->control
    panel->system->hardware->device manager)and locate the ethernet adapter.
    Uninstall the ethernet adapter. Now exit the device manager and reboot. XP
    should redetect the ethernet adapter and reinstall it. In its default
    configuration, it should have DHCP turned on. Also, make sure that you turn
    on windows firewall.

    If you can only manually configure your computer's IP address (btw: if the
    previous step did not fix the ethernet adapter, there is something wrong
    with TCP/IP on that computer), the manual settings you want to use are as

    (1) IP address: Look at the IP addresses of your other computers and add 20
    to the last number (e.g., if one is at then use something like IP addresses are usually handed out sequentially by the
    router so it should not dynamically assign this address unless there are a
    lot of computers connected. Alternatively, if you know at what number the
    router starts assigning addresses (it could be, then you can
    choose a number that is just below that range (e.g., It is
    important that the IP address you choose is not currently being used by
    another computer on your network.
    (2) Subnet: For home networks, this is almost always (this
    means that all packets sent to IP addresses that do not share the first
    three numbers with those of your computer are sent through the gateway).
    (3) Gateway: This is the IP address of your router. It may be,, or similar. Running "ipconfig /all" in a command prompt on one
    of the properly functioning computers will reveal it.
    (4) DNS servers: Get these by running "ipconfig /all" from one of the
    working computers. Alternatively, connect to your router's configuration
    page and look at the DNS entries there. You usually enter three; although,
    one is enough (unless that one is temporarily offline).

    Finally, make sure that you are using encryption with your wireless clients
    (WPA2/AES > WPA/TKIP > WEP) and change the default password on your router.
    If you do not do this, then anyone can connect to your network and also
    change settings on your router (or, in some cases, upload new or potentially
    bad firmware).

    Thanks for helping me out.

    I uninstalled the Ethernet adapter. Following reboot, it was
    reinstalled. I did ipconfig /all and saw that dhcp was enabled.
    Autoconfig was enabled as well. However, it gave me as autoconfig IP
    address I still was unable to connect.

    Next, I manually changed the IP address following your suggestions. I
    made sure it was different from the laptops. Also entered the DNS
    info. Windows now told me that I was connected. However, when I did
    ipconfig /all, it showed that Dhcp was not enabled. It also showed
    that IP routing was not enabled. Do not know if that is helpful.

    I am still unable to connect to the internet. The browser tells me
    that it cannot find the server.

  14. If you manually enter the IP address, then DHCP will be turned off. IP
    routing should be off.

    Can you ping the computers on your network? Have you checked the ethernet
    cable for problems? Try connecting to a site like with it's IP
    address ( Is IE configured to use a proxy (you should
    not be using a proxy)?

    I still think that the TCP/ip stack is corrupt,

    try this, this is straight from DELLs website on how to rebuild
    the winsock layer

    It won't hurt anything, just rebuilds the winsock. (ie turns loose
    the ip and lets everything work properly.)


    To rebuild the winsock layer in Windows XP, perform the following

    Click the Start button, and then click Run.
    The Run window appears.
    Type cmd in the Run window, and then press the <Enter> key or click
    The command DOS box appears.
    At the prompt, type :

    netsh winsock reset,

    and then press the <Enter> key.

    The message Successfully reset the Winsock Catalog appears.
    Close the command window and reboot the system.
    The internet connectivity will function normally again.


    I've seen this problem since SP1 , you get the 169 ip or "little or no
    connectivity" or weird do connection problems when you do a
    repair, or disable/enable. Usually by doing a disable/enable or
    uninstalling the NIC and letting winXp re-install it the problem is
    cured, but i've also used the above info the cure the problem.

    let me know if this works,

    See download update
    If it still fails download WinsockXPFix.exe

    Ted, Mar 29, 2005
  17. Argh. That removes all 3rd party LSP (Layered Service Provider)
    chains and resets everything to the original MS defaults. Most of the
    spyware removal tools and some browser plugs will need to be
    reinstalled after that. There are also complications per MS.
    Too big a hammer, methinks.

    Instead, download and run one of these:
    It removes an gaps and corrupted entries, doesn't totally hose the LSP
    chains, and leaves the plugins intact.

    You may wanna also look arount the LSP chain list before attacking:
