I have just received my Bt plus mini hub and am trying to change the wifi password.
I have successfully changed the SSID but when I change the password the box becomes red with a message say that the password should be between 8 and 32 digits.
I entered 10 digits and hit apply, nothing happened and after going out of the screen and back again the original password has returned.
Not the end of the world but it's a pain having to refer to the card every time I log in a new device.
Any clues, or am I stuck with the issued password?
