NO Internet connection where one existed before

[John DeVaux]

I own a Dell Precision 670 Dual xeon 2.8ghz 4gb memory. I just loaded win 7 on it this morning. Went to windows update and got the latest critical updates w/ some stuff for explorer 8. Also some drivers for my hardware. Since then I have been unable to connect to the internet. I'm on now with a Compaq gaming pc going through a dlink router and dsl modem. I using essentially using the same connection through a different port on my router. I tried ping through ipcongig and all 4 packets were lost. Win 7 networking says I'm connected to the internet. But openning browsers(both IE 8 and foxfire) only results in timeouts. I also cannot update av, firewall, or spyware products. I figure since pinging doesn't work all the stuff after it wouldn't but I want to provide as much information as possible to help with trouble shooting. Also when I go into device manager, I don't have any warnings that my gigbyte ethernet connection is not working.

Do a system restore around the updates or roll back the drivers in device manager that were installed - you wouldnt think it would be caused by the updates - then reinstall the drivers from windows update 1 at a time - and checking your connection is ok - ethernet driver would probably be the most likely. Do the following first as its more than likely a problem with software.
Did you reboot your pc to see what effect that may have. You may be able find a program, or addons for IE8 causing the problem - try keeping IE 8 as your default browser - to start IE 8 with no addons - start - all programs - accessories - system tools - ie8(with no addons)

Other solutions I found:
you go to Internet Options > Connections tab > LAN Settings > Click the box "Use a proxy Server for your LAN... and than hit apply and refreshed and all works

1. Open Internet Explorer.
2. In the "Tools" menu, select "Internet Options".
3. Click on the "Connections" tab.
4. Click on the "LAN Settings".
5. Clear the entries in "Use automatic configuration script" and uncheck "Automatically detect settings."
6. Uncheck "Use Proxy Server for your LAN", and click "OK" to accept the changes.
7. Quit Internet Explorer.
8. Open a new Internet Explorer window to test the problem.
