How to Set Up a Guest Wi‑Fi Network
A guest Wi‑Fi network gives visitors internet access without putting them on the same network as your phones, laptops, TVs, printers, cameras, or smart-home devices. It is a simple privacy feature available on many modern routers and mesh systems.
How to set up a guest Wi‑Fi network
- Connect to your home Wi‑Fi network.
- Open your router settings page or manufacturer app.
- Sign in with the router administrator account.
- Look for Guest Network, Guest Wi‑Fi, or Guest Access.
- Turn on the guest network.
- Create a separate network name and password.
- Save the settings and test the new network with a phone.
Choose a good guest network name
Make the guest network easy for visitors to recognise without including personal details such as your surname, apartment number, or address. For example, use a simple name such as HomeGuestWiFi rather than your main network name with “guest” added to it.
Use a separate strong password
Your guest network should have its own password. It can be easier to share than your main password, but it should still be long and difficult to guess. Change it after a large gathering or whenever you no longer want old visitors to have access.
Keep guests separate from your devices
Many routers offer a setting called Allow guests to access local network, Intranet access, or Device isolation. Turn this off when possible. It prevents guest devices from reaching devices on your main home network, such as printers, cameras, network storage, and smart-home hubs.
Should you use 2.4 GHz or 5 GHz for guests?
If your router offers both bands, leave both available unless you have a specific reason not to. The 2.4 GHz band has better range, while 5 GHz can offer faster performance closer to the router. Many modern routers choose the best band automatically.
What if your router has no guest network option?
Check the router app and advanced wireless settings first. Some internet-provider routers hide the option or do not support it. If the feature is not available, you can share your main Wi‑Fi password temporarily, then change it later if needed.

Frequently asked questions
Does guest Wi‑Fi slow down my internet?
It uses the same internet connection as your main Wi‑Fi, so many guests streaming video or downloading files can affect performance. Most routers let you set limits or pause the guest network if needed.
Can guests see my devices?
They should not be able to when guest isolation or local-network access blocking is enabled. Check your router’s setting carefully, because wording differs between brands.
Should I leave guest Wi‑Fi on all the time?
You can. If you rarely have visitors, you may prefer to turn it on only when needed. Leaving it on is generally fine when it has a strong password and guests are isolated from your main network.
