I start the computer and everything works fine. After a few hours my internet connection disappears. The computer says that it is still connected but can't communicate with other sites. Once I restart the computer, it is back in working condition, and loses connection again eventually.

Try these simple tests when it loses the connection.

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

Type the following commands, one at a time, followed by the Enter key:

IPCONFIG

PING <computer_IP_address>

PING <default_gateway_address>

PING 216.109.112.135

PING yahoo.com


Right click in the command window and choose Select All, then hit Enter.
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.


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.

This appears to be a good connection, you can ping Internet sites by name. Did you do this when you lost the connection, or after you rebooted?

So, that was the IPCONFIG when the connection didn't work? If so, that points to a browser issue, not an Internet connectivity issue. Perhaps you have a security product that is malfunctioning? Maybe you have malware that suddenly grabs onto the machine?

First off, try booting in Safe Mode with Networking, see if that allows the browser to connect.

Can you run for an extended time in safe mode to see if it makes a difference?

Have you tried a different browser? Try with FireFox and see if you see the same symptoms.

Sounds a lot like malware since it runs for some period of time before dying.
