Can't connect to wifi

Have you tried rebooting your router by unplugging it for 30-60 seconds?

Has nothing to do with the Router, I am having the same problem with my iPhone 6 plus since upgrading to the latest iOS version... it connects and immediately disconnects. Kept asking me for the password and although I entered the correct password multiple times, it keeps saying that the password is incorrect... which is B.S., because if it was incorrect or it had changed, I wouldn't be on wi-fi on this laptop that I'm using to type all this.

I even reset my network and powered off and back on the iPhone... and still having the same issue, the only thing that has changed on my phone (and I never connect it to a laptop, just to an outlet) is the iOS update.... so the issue is in fact with whatever they broke on it.

It still wouldn't hurt to reboot the router, would it? Then you could absolutely cross that off of the list. There are other things you can try to fix this but please try that first just to humor me. Then post back here with your results.

1. Settings > Wi-Fi > CHOOSE A NETWORK > tap the blue i next to the network name > Forget This Network

2. Settings > General > Reset > Reset Network Settings

I can't connect to ANY of the 3 Wi-Fi networks where I work. Resetting the router really isn't an option!

I agree! I have done EVERYTHING recommended, and I still am getting "incorrect password" for ALL 3 wi-fi networks at my job. I checked with tech support. NONE of the passwords have changed. Everything was FINE until the update!!!

Not an option!!!

Is it just your work's wi-fi network? Have you tried it on other wi-fi networks?
