Q: iphone 4s and ipad 2 require old wireless passwords
I changed the wireless password on my Airport Extreme 3 days ago. I have 5 pcs (4 windows and 1 imac), 2 fire hds, 1 samsung s5, 1 android nexus 7, 1 iphone 4s and 1 ipad 2. All the devices that do not run iOS are able to connect to my wireless network using the new password. My iMac connects too. The iphone 4s and ipad 2 refuse to connect with the new password, but continue to connect with the old password. My daughter has an iphone 6 and that connected with the old password at first. But after a couple of hours, her network connected and she had to reconnect with the new password.
I consider this to be a security problem because people who have visited my home over the last year still have my old wireless password on their devices, and if their devices are old, like my iphone 4s and ipad 2, their devices will continue to work.
I changed the wireless password to make my network more secure, but it's not secure if the older devices continue to work with the old password. Is this a bug in iOS? All devices are running the latest versions of iOS.
iPad 2, iOS 9.2.1

I played around with changing the password on my secondary wifi router. I used my iphone 4 ios 7.1.2.
What I did. Set a wifi password on my secondary router. Logged my iphone onto my secondary router. Changed password on my secondary router. My iphone when merrily on its way without complaint. When I looked in my wifi settings, I noticed my iphone had changed to my primary wifi router.
the iphone and ipad automatically switch between working wifi networks. I noticed that my computers are dumb and I have to switch manually between networks. Pita. [ actually, I am recalling this from memory ]
Could your iDevices be switching to a different wifi network?
