I had to replace my router , in the process i put in the wrong wifi passwords and they locked . i,m unable to unlock so i can change password. consequently i currently have no wifi on phone only cell. If someone can help me with this then i will enter password off router and hope this connects the wifi. thanks Keith
Go into Settings, WiFi and tap on the connection with the wrong password. An option to “forget” the connection will appear. Once forgotten you can connect to it again with the new password.
