Just finished a long hour trying to figure out why I could not get connected to the internet (when the problem first presented itself, I took a nap to see if it the problem would fix itself). I restarted and ran a virus scan, then tried to connect to the network and discovered I had inadvertently hit the button that turns off the wireless capabilities of the laptop. Sigh.
