Here's the problem. From settings > WiFi I select my network and type in the pw. I get the checkmark next to the network name and the little wifi symbol appears in the upper left hand corner....but nothing will connect. I've tried setting the DNS to 184.108.40.206 but still no luck. There's another network in my building (without the little lock...no password) that I used to be able to connect to, but not any more. Just says "Unable to join network" Any ideas?
