    My laptop can connect to my DSL modem/router via ethernet cable or wireless, but none of my web browsers (IE and firefox) can access any websites regardless of the type of connection. The same router also serves a desktop computer and that PC can access the Internet perfectly fine. Yesterday, I brought my laptop to a friend's place hoping he could help me, and when my laptop was connected to his router via ethernet cable and by wireless, the laptop was able to access websites via both types of connections. This loss of Internet access started last Friday evening. I do not remember changing any settings for any devices. What could be the problem?

    Please supply the following info, exact make and models of the equipment please.

    Name of your ISP (Internet Service Provider).
    Make and exact model of the broadband modem.
    Make and exact model and hardware version of the router (if a separate unit).
    Model numbers can usually be obtained from the label on the device.
    Connection type, wired or wireless.
    If wireless, encryption used, (none, WEP, WPA, or WPA2)
    Version and patch level of Windows on all affected machines, i.e. XP (Home or Pro), SP1-SP2-SP3, Vista (Home, Business, Ultimate), etc.
    The Internet Browser in use, IE, Firefox, Opera, etc.




    Please give an exact description of your problem symptoms, including the exact text of any error messages.



    • If you're using a wireless connection, have you tried a direct connection with a cable to see if that changes the symptoms?
    • For wireless issues, have you disabled all encryption on the router to see if you can connect that way?
    • Have you connected directly to the broadband modem to see if this is a router or modem/ISP issue?
    • If there are other computers on the same network, are they experiencing the same issue, or do they function normally?




    On any affected computer, I'd also like to see this:

    Hold the Windows key and press R, then type CMD (COMMAND for W98/WME) to open a command prompt:

    Type the following commands on separate lines, following each one with the Enter key:

    PING 206.190.60.37

    PING yahoo.com

    NBTSTAT -n

    IPCONFIG /ALL

    Right click in the command window and choose Select All, then hit Enter.
    Paste the results in a message here.

    If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.

    Below is the requested information:

    ISP is Verizon DSL

    modem is called "Verizon Wireless DSL Modem/Router", model # GT704WG. It has 4 ports for ethernet cables, one USB port, and an antenna for wireless

    laptop can connect to the modem via wire and via wireless. Using wire and wireless connections at the same time does not fix the problem.

    Wireless uses WEP encryption

    Laptop uses Windows XP media center edition, service pack 3

    browsers
    affected are IE and firefox

    For IE, it always shows "cannot display the webpage" after a long time

    For firefox, it always says "Connection interrupted-the connection to the server was reset while the page was loading. The network link was interrupted while negotiating a connection. Please try again."

    Here is the data from "cmd":

    Let's try a stack repair, then please post another IPCONFIG /ALL


    TCP/IP stack repair options for use with Windows XP with SP2/SP3.

    Start, Run, CMD to open a command prompt:

    In the command prompt window that opens, type type the following commands:

    Note: Type only the text in bold for the following commands.

    Reset TCP/IP stack to installation defaults, type: netsh int ip reset reset.log

    Reset WINSOCK entries to installation defaults, type: netsh winsock reset catalog

    Reboot the machine.

    Let's try some pings, that looks good.

    Try these simple tests.

    Hold the Windows key and press R, then type CMD (COMMAND for W98/WME) to open a command prompt:

    In the command prompt window that opens, type type the following commands one at a time, followed by the Enter key:

    IPCONFIG /ALL

    PING <computer_IP_address>

    PING <default_gateway_address>

    PING <dns_servers>

    PING 206.190.60.37

    PING yahoo.com

    Right click in the command window and choose Select All, then hit Enter to copy the contents to the clipboard.
    Paste the results in a message here.

    <computer_IP_address> - The IP Address of your computer, obtained from the IPCONFIG command above.

    <default_gateway_address> - The IP address of the Default Gateway, obtained from the IPCONFIG command above.

    <dns_servers> - The IP address of the first (or only) address for DNS Servers, obtained from the IPCONFIG command above.


    If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.

    I do not mean to double post, but just before I re-installed my DSL software and that got the Internet on my laptop to work again (wire and wireless work fine now, IE and firefox are both able to load websites again). Anyway, thank you for all your help!
