Hello @Kinderschool,
Thank you for joining here on the Community Forums! I once had this happen to me as well, so I completely understand wanting to keep your Wireless Network Key Password secure and updated. It would be a pleasure to help get this resolved for you.
Quite a few customers have had similar questions around changing their Wireless Network Key Password, so we’ve come up with an easy to follow guide that will walk you through the process.
