Why I can’t connect to internet on Mac after Changing WiFi Password

Sometimes we realize that our WiFi is hacked or someone else using it without permission. In this case, the best solution is to change the password to prevent others using it. Always use WPA method to secure WiFi, because WEP security is easy to crack.

After Changing WiFi Password you may realize that your Mac Can’t connect to the net and always gives an error with network diagnosis option. It doesn’t matter how hard you try and run diagnosis, you won’t be able to connect, and it doesn’t even ask for the new password.
