Don't be too hard on yourself...you might be amazed how many times, after hours of troubleshooting, something still doesn't work, because it's not turned on or a cables not plugged in. I spent about an hour on the phone with a guy, after ATT got him all hooked up and said he was good to go wireless, who couldn't get his iphone to connect. He had a desktop plugged in with a good internet connection, we tried this, and that, resetting settings, restarting devices, "his" network would appear, then disappear, ...turns out the "all in one" box ATT installed, and gave him a security code for, was just a cable modem with no wireless capability. "His" network was someone else in the neighborhood.
