Do the stack repair again, then please post 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 IPCONFIG command output! Do NOT type <computer_IP_address> into the command, that won't work. Also, the < and > in the text is to identify the parameters, they are also NOT used in the actual commands.

Do NOT include the <> either, they're just to identify the values for substitution.

IPCONFIG /ALL

PING <computer_IP_address>

PING <default_gateway_address>

PING <dns_servers>

PING 74.125.45.100

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. (For Vista/Win7, the IPv4 Address)

<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.

Well, you can't ping the DNS server, which may or may not be an issue. However, you have a good Internet connection, you can ping Internet sites by URL.

When you posted this, could you successfully browse? We need to see those diagnostics when you have the failure.

You still have a good IP configuration, but cannot ping the router. Several or half a dozen possibilities.

One is a bad ethernet cable.

Another two, as mentioned before, are a corrupted security application or ethernet driver.

[etaf]

just to clarify

I did this while i was in offline mode [ disconnected ]

This was when the PC disconnected on its own - nothing you set ?
A little confused on offline mode

[Vagueheart]

Yep its when the pc disconnected on it's own.

It's finally weekend soon so the ethernet cable ,etc, will be checked by my family member soon I hope @_@.

[Vagueheart]

My brother-in-law changed the network card + uninstall mcafee.

It's been about 2 hours and network is still working fine.
