No internet access when boot up.

Clarifications

Than the TCP-IP Stack being confused.

What does the Device Manager show of the Ethernet Port on the computer when it's in the No Run situation?

Also if you stop the TCP-IP and restart it do you now have a working Internet connection?

I would suggest you to check the router configuration it has to be set to AUTOMATIC to receive response from the modem (ISP). to do this just follow the steps:

*start-> cmd -> ipconfig
*make a note of the default gateway
*open up internet explorer and type the default gateway
*it will take you to the router page
*make sure the internet connection type is set to Automatic

If this does not work configure the router completely with the help of Internet Service Provider.

Hope this helps.

Open IE
Click on the TOOLS tab
Click on INTERNET OPTIONS
Click on the CONNECTIONS tab
Click on the LAN SETTINGS button
If on, click off the "Use a proxy server ..." box
Either click on the "Automatically detect settings" box or have no boxes click on

Not sure if this helps your problem or not.

Assuming 192.168.1.1 or 192.168.0.1 for the router, give it 192.168.1.2 or 192.168.0.2 or any other address that doesn't conflict. Also, are you seeing network activity on the router activity LEDs and the diagnostic LEDs at the back of the ethernet port after boot?

It's come in handy at times. I hard boot the router, leave the power off for 15-20 seconds then plug it back in.
Thw manual for your router. http://kbserver.netgear.com/pdf/wgr614v6_ref_man_20Apr05.pdf
My router allows me to save the software configuation. If the router ever 'acts up' I simply reload the configuration file. Even without that it's just a matter of a few minutes to set everything up again.
