Can't ping the default gateway or access the Internet

Discussion in 'Windows Networking' started by =?Utf-8?B?Q29saW4=?=, Oct 4, 2005.

  1. Hi all,

    Could someone be so kind as to help point me in the right direction. I have
    a newly configured Windows 98 computer on an internal, private network using
    192.168.1.x. It's obtaining the proper IP configuration automatically via
    DHCP. From this computer, I can connect to the file server (192.168.1.10),
    web server (192.168.1.11), and I can print to a network printer
    (192.168.1.100). The problem is I can't ping the router (default gateway)
    and therefore can't get to the Internet. Any pointers? Thanks in advance.

    Occasionally the broadband modem has a default assignment of
    the same IP address as the router. I am going to assume when
    you say "router" this is some sort of access point that has
    functions, such as assigning DHCP addresses, a firewall, WEP
    security, etc., and it is not merely a "dumb" concentrating
    hub or switch (which cannot be pinged anyway). I also assume
    you can "ping" this "router" from the other computers. If
    you can ping from the others, but not the Win98 machine,
    turn off the Win98 firewall (if any). Also make sure that
    the Win98 is pulled into a regular port on the router and
    not the LAN port. In network setup, in the TCP/IP for the
    NIC set-up, insure that you are using DHCP, WINS is
    disabled, and the Gateway and DNS server settings are empty
    and disabled.

    If the Win98 NIC is a WiFi, insure that both the Win98
    machine and the router/access point are both using or not
    using WEP or WPA and if using protection, the coding is all
    the same.

    I am also assuming the Win98 machine can ping the other
    devices, meaning that the cable is good and the router seems
    to be 1/2 functional, anyway.

    If the above six conditions are OK (ping from others, ping
    to others, correct port, no firewall, and pure DHCP, WEP set
    proper), disregard my next suggestions, since I have not a clue.

    If, after fixing the cable(s), and clearing the firewall,
    purifying DHCP, setting WEP and not being able to ping the
    router from any computer, try this:
    Run WINIPCFG from the DOS prompt, choose the network
    interface card (NIC) making the connection, and click on
    more info. Confirm that the DNS Servers (the broadband
    modem) has a different IP address than the default gateway
    (the router). Note those two IP numbers. If they are the
    same, change the gateway IP address.
    Since you are using DHCP, if you needed to change an IP
    sequence you will only need to change the gateway address.
    The rest of the DHCP machines will reassociate when each
    machine is rebooted after you do the following:
    Fire down all your machines.
    Direct connect from the Win98 with an Ethernet cable or USB
    (what ever) to the hub/router (not broadband modem), fire up
    Win98 and use your network browser (IE, Mozilla, Netscape,
    what ever) to connect to the router with the existing
    gateway IP address.
    Figure out how to change the router IP address. I suggest
    192.168. Dif#. 1. Power down router for 30 seconds. Fire
    down Win98 computer. and then reconnect all machines
    normally and fire them up. Record the new IP number assigned
    to the router. If you ever have to go back to factory
    defaults, push in the router reset button for 30 seconds,
    power down the router for 30 seconds, and you will back to
    square zero.

    Report back for more suggestions if none of this cures things.
