My Macbook Pro (v10.6.8) is constantly automatically connecting to a neighbor's wifi - event though I've never connected to that network, and I have my own Wifi connection prioritized. The system is constantly scanning for Other Networks and lists all of my neighbors' network ahead of mine. I frequently need to reset the connection. How do I remove the list of available networks, OR disable the system from scanning the neighborhood, OR lock the Wifi connection to my in-home network? Thanks!
You could check your "Preferred Networks" and make sure your WiFi Access point is listed first.
To do this Open the System Preferences and select "Network" then Select the WiFi network and click the Advanced button:
With the WiFi tab selected from the Advanced sheet you should see a list of your preferred networks, Add, Remove, Reorder as you see fit.
