If you need to change your 192.168 100.1 password, there are a few steps you'll need to follow. First, open up your web browser and navigate to http://192.168100.1/. This will bring you to the login page for your router's admin panel. From here, enter in your username and password (the defaults are usually admin for both). Once you're logged in, look for the Password or Security settings and find where you can change your password. Enter in your new password twice and hit save/apply - that's it!
