ipad mini: wifi "incorrect password" now, dropping Wifi yesterday
My iPad mini (iOS 8.3) started having problems with my home WiFi yesterday. It would just drop the WiFi connection out of the blue (while in use, and working) and fail to reconnect. Restarting the iPad mini fixed it a few times but that doesn't work anymore. Changing the WiFi router's channel fixed it for a while, but then it dropped again. Now I can't connect at all. I've reset the network settings and now the iPad insists that the password is wrong, although all my other devices work fine. My router is a BT HomeHub5. I've had it for a few months now and it hasn't caused me any issues before yesterday. The iPad mini hasn't had any WiFi issues since I bought it, until yesterday.

It joined the network just fine a minute ago, then it dropped again.
Any ideas what this is all about? I haven't effed with the settings of my router, iPad or anything else recently, and all my other devices work fine.
