You will find in System-Router menu: Setup, Wireless, Security etc..
Select Wireless. It will open Basic Wireless Settings, Wireless Security, Guest Access etc. Select Guest Access. It will show option "Allow Guest Access" Yes/No - select "No".
Guest possibly cannot change settings but I have no use for this option and disabled it.
