This is a simple triage approach to restoring a lost WiFi connection. That means the most likely, easy to fix solutions will be presented first. What you see in the photo is not what you want to see. This Instructable is for the person who does not feel qualified to resolve computer problems, but needs his or her computer to work without calling in a technician.

Click on the four bars next to the speaker symbol (lower right corner of the Windows screen) and this box pops up. Look for the name of your personal local network. We named ours "OurNetwork." As noted in the upper text box, "Connected" may only mean your router is sending a signal. It does not guarantee that the modem is feeding a WiFi signal to the router. Still, you want to see the word "Connected." The other networks belong to our neighbors. They are usually secured by a password, so I cannot simply connect to their networks.
