Tom said if you are having authentication problems to log I to your iPhone address if you think you password maybe wrong. How can you update it?

You can't update your WiFi password from anything other than logging into your modem/router. That is what it is stored. The other devices only access the WiFi, they can't change the password or settings.

Now you can, through an Ethernet connected device (or a device that actually does connect to your WiFi) log into the modem's settings and confirm or change your password for the WiFi.
