study carefully he is Asking how to change his own wifi accesspoint password not others or router.
we would NOT help with changing a router or accesspoint's password.
If he needs help in getting his laptop to connect but can't because Windows has a bad stored WPA2 key, then we can direct him/her on where to type in the correct wpa2 key. We CANNOT help him change a hardware password.
Danny2000: he is not asking how to change router or others accesspoint password.he is asking how to change his own accesspoint password means own wifi accesspoint password. example: if u connect 2 bluetooth device type some password same in both devices thats it he is asking how to do it in wifi with his own device not others bluetooth password. ok.
