Hi Again,
I just tried to access the internet with the Wireless capability disabled and the ethernet cable pluged in. Everything was just the same.
I should mention again that in the normal mode, the computer does connect somewhat to the internet. I have a program called "CallWave" and once the connection is complete (both wireless and wired) the program opens and works. (CallWave is an online telephone answering service) Furthermore, at least once since this problem started I have recieved Microsoft updates via the automatic download. Finally, the internet access through a browser was working until one day it just didn't. Since this isn't my computer, I don't know what the kids did just before the problem happened, and they can't seem to remember.
It may not help, but I ran a connection diagnostic while the Firewall was disabled, the Wireless was disabled, and only the ethernet connection was working. Here is that report:
