Wifi password changed, devices still accept old password

[DeadEyeD]

Hi,

I've changed my wifi password as per the procedure of logging into the router settings at http://192.168.0.1/. I can see the new password on both the 2.4GHz and 5GHz networks yet my devices won't accept this and will still connect using the original supplied password. I've also tried restarting the router but the situation still persists. Any ideas as to why this is happening or any solutions? Thanks

@DeadEyeDIf you are trying to reset the router back to defaults hold in the reset button for at least 20 seconds.

Do you have Sky Q by any chance?
You may need to power down all Sky Q devices as well. 

[DeadEyeD]

Yes, we have Sky Q. So power that down when attempting to change the wifi password?

@Highlinder

Not attempting a router reset but will give that a go if the above fails to solve the problem, cheers.

Just after the password has been changed. My suspicion is that the Q nodes are holding the old WiFi password since they act as boosters for your network.
