Alright, so I have two seperate cases.

Computer 1: just reformatted and reinstalled all the drivers from the cd but no network is detected. the 1394 connection says enabled though but there is no lan connection.

Computer 2: had a lot of viruses and stuff so I used some scanners and got rid of most of it. however, the internet doesnt work anymore. the lan connection is detected, but unable to go online

i also have a 3rd computer and laptop connected to the network and they both connect fine.

thanks for the help! i been trying tons of things and still cant get it to work

On the non-working computers, please do both of the following steps.


Hold the Windows key and press R, then type devmgmt.msc

Please respond to all the following steps.
  1. Under Network adapters, please tell me all the devices listed.
  2. Are there any devices under Network adapters that have a red x displayed?
  3. Also, are there any devices anywhere in the Device Manager display with yellow ? or ! displayed?



Hold the Windows key and press R, then type CMD to open a command prompt:

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

Note that there is a space before the /ALL, but there is NOT a space after the / in the following command.

IPCONFIG /ALL

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.

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.

Well, It appears that Computer 1 has no network drivers installed, so that would be the first thing to fix. Install the chipset drivers first, then the network, sound, and video drivers.

The second computer also appears to have driver issues as well. I'd uninstall ALL AV and firewall components first, then uninstall the network drivers. Reboot, install the network drivers and see if it's working before installing the AV or firewall applications again.

For each of these after the repairs, I'd like to see another IPCONFIG /ALL

Well, it's not recognized by Windows, so I'd have to assume it's not the right driver.

so after a long time spent googling and looking through many other troubleshoot threads, i downloaded Intel 825xx 10/100 Platform LAN Connect Device which wasnt on the cd or seem related to my driver at all. but it somehow fixed the internet problem on computer 1.
