There are a lot of posts on this site and I am not happy with the software they use for the amount of people they have on this site. Therefore, your post got pushed to the bottom and I don't check those after a certain date. To insure a quick response, start a new thread that quickly summarizes what we were discussing.
First off, you cannot assign IP addresses to the computer. Change it back to have it assigned and your Internet connection will repost. You will have to unplug/restart your Internet Modem (cable/dsl).
If you followed my advice and it still occurs, your problem is not related to your setup.
You probably installed a new network card in the computer you are having problems with recently. If the computer is a little older, you may be having several issues that I have experienced in the past.
It is possible that your CPU fan is not operating and may need to be replaced. Your problem is usually associated with an overheating processor.
Also, the additional network card requires more power. I found that in older systems with lower watt power supplies had similar problems after upgrades supplying power to the processor. Look at the power supply fan and make sure that it is turning and not making noise. Even if the power supply works but there is no fan, it needs to be replaced before it does damage to your system. You may consider a 300 watt power supply (or greater) for a replacement. Make sure someone helps you out with selection of the power supply and install. They usually range from $25 on the Internet to $50 at the electronics store of your choice.
Hope this helps. Feel free to post back if it does not for other solutions.
