    last night i shut my desktop down and this morning when i started the computer i had serious issues.

    Issue 1 (non network related):
    My computer was not loading, it wouldn't even load into the bios. i began disconnecting all devices (external HDD, keyboard, etc), still didn't solve the problem. I later solved the issue by tinkering with the RAM sticks. Computer now loads into windows xp.


    Issue 2 (network related).

    Since this morning i haven't been able to connect this pc to the internet. Originally this pc is hardwired to my router (linksys WRT54G) and i'm using a Scientific Atlanta DPC2100 modem from Time Warner. I'm sending packets, but not receiving, thus getting a limited to no connectivity error.

    Things i've done that have resulted in the same problem:

    1. Connected the problematic pc via Ethernet (on board) to the modem/router.
    2. Installed a pci network card and drivers and tried to connect to modem/router.
    3. connected pc to modem via usb.
    4. uninstalled and reinstalled the drivers for the modem, for the on board network card, and the pci network card.
    5. Performed a System Restore to a week ago.
    6. Plugged cords into different outlets
    7. Tried different Ethernet and USB cables

    Things i've done that have had success:

    1. Connected a 2nd pc to modem via Ethernet and was able to access the internet.
    2. Connected a 2nd pc to the router via Ethernet and was able to access the internet.

    Problematic PC Specs:
    Pentium 4 3.0GHZ
    160GB RAM
    3.0GB RAM
    Windows XP SP3

    thank for taking the time to help, i really need it.

    i forgot to add, that while i was trying to find the reason why my pc wasn't loading i had disconnected the router and modem. After finding the solution (RAM) and connecting the modem and router the wireless network that once existed is no where to be found.

    I would start troubleshooting from the command prompt

    First, I would check that the router is issuing an IP and DNS properly. I'm guessing this is where the problem is because of the limited connectivity message and that another PC can access the net.

    You can stop at whatever step below fails to give the proper response.

    Start > Run > type cmd and click ok. At the prompt type and enter the command -
    ipconfig /all
    The default IP for that router is 192.168.1.1. Your computer likely has an IP close to 192.168.1.2 and the DNS server as 192.168.1.1 or maybe 192.168.100.1
    The section to pay attention to should look like this:
    Dhcp Enabled. . . . . . . . . . . : Yes
    Autoconfiguration Enabled . . . . : Yes
    IP Address. . . . . . . . . . . . : 192.168.29.27
    Subnet Mask . . . . . . . . . . . : 255.255.255.0
    Default Gateway . . . . . . . . . : 192.168.29.1
    DHCP Server . . . . . . . . . . . : 192.168.29.1
    DNS Servers . . . . . . . . . . . : 192.168.29.1

    Next, I would ping the modem. The default IP for your modem is 192.168.100.1. The command to type and enter at the prompt is -
    ping 192.168.100.1

    If all went well I would ping a public DNS server
    ping 4.2.2.2

    And then ping a site
    ping google.com

    The step that fails should tell where the issue is. If in ipconfig you show DHCP as NO, then it is disabled or the service isn't running.

    Can you uninstall and reinstall your ethernet adapter again?

    In your case, it should appear as "Intel(R) PRO/100 VE Network Connection" in Device Manager.

    Afterwards, if successful, try : ipconfig
     
  14. thedon01

    thedon01 Corporal

    uninstalled successfully, but where would i find the drivers to reinstall? Intel's site, driver disk that came with the pc, etc?

    okay i did, i'll reinstall them and am I just running an ipconfig in a command prompt afterwards?

    If so can i post you the results in the morning? It's almost 4 a.m. where im at, hope that's alright?

    thedon01 Corporal

    i went ahead and installed real quick and this is what i got:

    the installed version of Intel ProSet is not supported for upgrades. you must uninstall it before installing this version. However the Drivers for Intel(R) PRO/100 VE Network Connection did show up in device manager afterwards.

    ran cmd > ipconfig and received

    Ethernet Adapter Local Area Connection 4
    Connection specific DNS Suffix......:
    Autoconfig IP Address.................:169.254.188.124
    Subnet mask.............................:255.255.0.0
