adding guest

There is no dedicated guest mode, but you could create an additional network on your gateway for their usage. I'm assuming you have the Arcadyan KVD21 5G gateway. Use the phone app to create a new network. After launching the app, tap the Networks tab on the bottom of the screen, then tap the "+" sign at the bottom right of the next screen. Create a new network with the parameters you choose. Give it a different name than your main network, e.g., KimkGuest. That's the network name (SSID) your guests will use. That will keep them off your main network and allow you to easily change the password from time to time for additional security. As an example, for a guest network, you might choose to hide your original network but leave this one visible, or visa versa, depending on your purpose in creating this new Guest network.

When you're done, scroll to the bottom of the page and tap Save. The gateway will reboot and you will now have both your original network as well as your new Guest network.

¡Buena suerte!
