Alright, here's the deal. My house has a network of 3 computers: my mom's XP wireless laptop, my dad's XP wireless desktop, and my Vista wired desktop. Now, the problem is that from time to time, my internet will just go out. I still have the network, but no internet. (the little icon just shows the computer icon, it'd have a blue globe if it had internet and a red X over it if it was disconnected) It does this for hours at a time, randomly, maybe a once or twice every 2 weeks. Restarting, unplugging and replugging the ethernet cord doesn't fix it. Meanwhile, my parent's XP's are working just fine. Any ideas what might be causing this? Our router is a WRT54G Wireless-G by Linksys.

Well, since the other computers still have Internet connectivity, you're probably looking at something running on your computer.

When this happens the next time, please do this.

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:

NOTE: For the items below in red surrounded with < >, see comments below for the actual information content, they are value substitutions from the previous command output!

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.

although, at the time i did those tests, the internet WAS working. Do you need me to do it when it's unactive?

[JohnWill]

Yes, I need to see the failing condition.

[xero1000]

alright, as soon as it decides to die on me, i'll tell you. It may be a while though
