Every time guests visit, someone asks for the Wi-Fi password. Sharing your main password means more people can access your home network, and you may have to change it later. A guest network solves this.
What is a guest network?
A guest network is a separate Wi-Fi network created by your router. Visitors get internet access, but they cannot see your computers, printers, cameras or shared files.
Benefits
- Your main password stays private.
- Visitors’ devices, which may have viruses, are kept apart from your own.
- You can change or turn off the guest password any time without disturbing your family’s devices.
How to set it up
- Log in to your router settings page or app.
- Look for Guest Network or Guest Wi-Fi.
- Turn it on for 2.4 GHz, 5 GHz or both.
- Give it a simple name, such as “Home-Guest”.
- Set a password with WPA2 or WPA3 security.
- Make sure “Allow guests to access local network” is turned off.
- Save the settings.
Useful extras
- Bandwidth limit: some routers let you limit guest speed so visitors cannot slow down your own use.
- Time schedule: turn the guest network on only when needed.
- QR code: many router apps can show a QR code that guests scan to connect instantly.
Good for smart devices too
Smart plugs, bulbs and some cameras can also be placed on the guest network, keeping them separate from your phones and laptops.
No guest option?
Older routers may not have this feature. In that case, consider a router upgrade, or change your main password after guests leave.
