I initially failed in trying to get two new Inspiron 530's I set up to initially connect to the internet. After many tries, I finally took my router out of the circuit, shut down the computer, unplugged the ethernet cable from the modem to the computer and rebooted the modem, either by unplugging it for 20 seconds, or in one case, hitting the reset button on the back of the modem. Then I replugged the ethernet cable from the modem to the ethernet port on the computer and rebooted the computer. I was able to access the internet.
When the router was reconnected, internet access was denied. This was cured by resetting the routers to factory default, (puching and holding reset button on back of router) and then reinstalling the router.
I hope this experience helps others.
