Many Wi-Fi routers give the Wi-Fi’s owner the option to create a guest network for people who visit. These allow guests to access and use the internet, but they can’t access other connected resources like shared folders or connected devices such as printers.
To set one up, access your router’s management software (usually accessible through your ISP’s site) and enter your router’s IP address, followed by your username and password. You’ll typically find guest network options in a dedicated section or under wireless settings. From there, you can create it, assign a name and assign a password.
