hello....you can't connect wired or wireless? Are there any other computers in the network that's experiencing the same issue as yours? Is it intermittent disconnection or you're totally disconnected for about a week now?

Can you pls. provide an ipconfig /all info of your computer?
click on Start => run and type cmd on the blank field. From the black screen, type ipconfig /all and please post the results here. Right click on the black screen choose Select All and Paste the results here.

Let's see this from each of the computers, the working and non-working ones.

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.

Thanks for info. very helful.

Are you able to ping the router at least? Click on start, on run field type the word cmd. From the black screen type the word ping 98.145.64.1 and press enter. Please post results here if there's any time out.

The following instructions will help you troubleshoot your disconnection issue. Pls. try each one at a time, then try connecting to the internet. If it works, you don't have to continue with the steps.

First: Let's reset the TCP/IP => Reset TCP/IP http://support.microsoft.com/kb/299357
I would do this also after the reset, an IP release and renew.
Click on start, on run field type the word cmd. From the black screen type the word ipconfig /release then press enter and again this time type ipconfig /renew. Now, see if you can access the web.

Second: Disable any Firewall/Security software such as zonealarm, McAfee etc.

Third: It won't hurt to scan your computer for any Malware/Spyware run Malwarebytes and see if it will detects and remove any Malware http://download.cnet.com/Malwarebyt...4572.html?part=dl-10804572&subj=dl&tag=button
Then try accessing the Internet.

Fourth: Updating your Ethernet driver might help as well. Here's an instruction:
Click on Start, right click My Computer => Properties => hardware tab => Device Manager => find your Network Adapters and expand it. right click on the Ethernet Adapter and choose Update Driver. If you have an ethernet driver CD have it ready. Choose Uninstall then re-install. Normally your Windows will do a Plug N play auto install for you, but just in case you might have your CD driver ready.

Let's pause here for right now, and update us.

Try unplugging your KVM switch for about a minute then plug it back in. Try to connect to the net.

Do you have a spare ethernet cable? You might want to give it a try to test it out.
Replace it then try accessing the internet.

or from the 4th solution that I gave you, I know that you did the update, but at this time, try uninstalling it then re-install, using the same procedure. Make sure that you have your CD driver.

if uninstalling didn't work you might want to replace your Ethernet card then.
