Q: Iphone 6 won't connect to wifi .. Says incorrect password which is not true. Ideas???

thank you everyone to help and the information

So, I was having this very same and very frustrating issue over the past couple of days..

Last week, I went out of town and stayed in a hotel. My son took his Xbox One and wanted to connect to the hotel's Wi-Fi but it requires accepting the terms, typically rerouting your device to a web page to do so. Well, this doesn't work using an Xbox. So, after searching the internet on how to do this, I found a video explaining how to use your iPhone's Wi-Fi address, in lieu of the Xbox's, to enable use of the hotel's internet through the Xbox. I followed the instructions, and it worked fine. Gaming and Netflix, here we come...

When we returned home from our trip, my iPhone automatically reconnected to our home's Wi-Fi network without a hitch. However, after a couple of days, my phone would not connect. It was asking me to enter the network's password and continually rejecting the correct entry. I tried everything I could find to do. Reset network settings on the iPhone, restarting my router, checking the advanced settings on my router, everything... I took several tips from these posts as well and no luck. Then I remembered that we had used my iPhone's Wi-Fi address on the Xbox last week. I just assumed that when we reconnected at home, the Xbox would go back to it's original state. So, I checked it out. Turns out, my iPhone's address was still in the Xbox which has been used several time since our return. So, I changed the Wi-Fi address on the Xbox to it's original address, and bada-bing, my phone was once again connected! So relieved!

So, if you know or maybe don't know if your gaming system was recently used this way, check it out!
