Windows 10: Why won't my wifi connect with the right password?

Hello, I am hoping someone can help me. I was watching YouTube videos on my laptop and did not realise it was not plugged in properly, so it died. After plugging it in again and turning it on again, the WiFi suddenly stopped working. It was working perfectly fine about 5 minutes before, even after it came on again it was working for a few minutes. When I try to connect, it asks me to enter "Enter the network security key", which I do but then it says "Can't connect to this network". The password is correct, as I've never changed the password on the router. Like I said, the wifi was working bef

Phone won't connect if I change wifi password

I've finally figured out what happened, but the problem is only temporarily solved.

I had changed my wifi password. And the phone won't connect with the new password. If I change the wifi password back to the old one it connects.

So it's definitely a phone issue.
I wish I could change my wifi password and have my phone working..

Try removing that connection from your phone completely and then setting up a new one from scratch.
