How to update Wi

I know how to update it actually. In network preferences just go to Advanced>Minus the wifi name>then add the wifi again.

This is too tiring and I do update my password frequently. Is there any way to do it easily? I don't want to go all over again if I change my password.

I also Tired of doing this. But Than I just Made Strong Password and than can't doing this Tired Work. Hope you should also Make Strong Password or Get Rid Off this Tired Work.
