Went to bed with working computer, woke up with the opposite

[thedon01]

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.

@handygal, i'm going to try your suggestions and i'll get back to you shortly. thank you

[thedon01]

Start > Run > cmd > ok > ipconfig /all

Here's what i received:

I stopped in your directions at this point because it didn't match anything in your directions. What's next?

[thedon01]

i continued with the instructions and here is what i received:

Again i tried Start > Run > cmd > ipconfig /all

[thedon01]

i'm sorry i forgot to include the

ping 4.2.2.2 results:
Same results as pinging 192.168.100.1

[thedon01]

any suggestions/directions?

[thisisu]

Try this command:

• ipconfig /renew

Let us know what error message you receive.

[thedon01]

tried it and nothing happened, it just went to the next line, no error message

[thisisu]

What about:

• ping 192.168.29.1

[thedon01]

it took a little time but this was the error message for ipconfig /renew:

an error occurred while renewing interface Local Area Connection: unable to contact your DHCP server. Request has timed out.

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

[thedon01]

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

[thedon01]

is this correct?

These will work too, same thing. Just make sure you select the 32 bit version (PROWin32.exe)

[thedon01]

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]

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
