Hi,
I have just got the BT Smart Hub 2 and I am wanting to change the WiFi password and everytime I put a new one in it say password rejected as it is easy to guess. The password is 24 digits and has upper and lower case letters and digits, no special characters.
How do I get it to accept my password, never ever had this issue in all of the routers I have used!
Try a password with less characters. It should take a password with anything between 12 and 63 characters but it might be worth trying to see if it is accepted.
If it still won't change try a factory reset of the hub and try changing the password again.
