Nexus 5 Wifi Connection Problems

[AC Question]

I just got my nexus 5 yesterday. I went over to a friends house and it connected to wifi perfectly fine. But when I got home it wouldnt connect. I input my password and it has no problem with the password. Afterwards it says authenticating and then says authentication failed. And then it says saved. I turned it on and off. Nothing. Airplane mode on and off nothing. Reset my wifi router nothing. Im out of ideas. Any help?

Will other phones connect to your wifi?
