My mac doesn't connect to my home network by default

My computer doesn't connect to my Airport basestation by default. The WiFi at the top bar is not connected, if I click on the WiFi symbol I see my connection and 2 of my neighbors, but none are connected by default. I always have to manually select my basestation. When I open Safari for the 1st time I get a "not connected to the Internet" type error. When I click diagnose and walk through the steps of selecting my location and basestation it connects without an issue.

I've gone into the System Preferences and tried to create a new location, but no luck. When I look in System Preferences and click into 'Advanced' my network is the only one listed in the Preferred Networks window. Why does it not connect by default. If I restart the computer I have to manually select my network again.
