just got a new phone Nexus 5 and am having problems connecting to my home wifi. I had it yesterday but no availability to koodoo cell tower. Took it back to store, they adjusted something and today I have no wifi! Is there a setting that I am missing. I reset phone, I toggled airplane on/off and I "forgot" original provider and then re-entered my correct password for home wifi. My home computer works so it is the phone. It gives an "authentication problem" with wifi symbol showing ? Can you help? Please!
