Ok so in my house I can usually connect to my neighbors wifi but for some reason today (and other times) it will just hang when I try to connect and eventually say "Could not connect to server" or w/e. Why does it not work sometimes? When I click the blue arrow to view the details of the connection, all the spots (IP, etc.) are blank. As I say it usually works alright but tonight it wont connect to anything. Any ideas?
