Guest network

Try your router's guest network first. You need no new device or subscription when the router isolates it from the main home network.

A guest network is a second wireless network on your router. Connected devices can reach the internet. Check the router's instructions to confirm whether the setting also blocks access to the main home network.

One router, two networksTwo separate networks come out of the router. The home network holds a computer and a phone, the guest network a camera, a bulb and a television. There is no connection between the two networks.RouterHome networkComputerPhoneGuest networkCamera, bulbTelevision
A router can keep the home and guest networks separate from each other.

Five steps

Setting names vary from manufacturer to manufacturer. Under each step is a list of the other names the same setting may go by, in Finnish and in English, because the label on the screen is what you are looking for.

Step by step

0 / 5 done

  1. Log in to your router's admin page

    The address is usually on the sticker underneath the router, and so is the first password. Type the address into a browser while you are on your home network.

    It may also be called: 192.168.1.1, 192.168.0.1, Hallinta (management), Admin

    If there is no sticker, look up your model on the provider's or manufacturer's site. Do not use a shared default password found in search results.

  2. Find the guest network setting

    Look under the wireless settings. The guest network may have its own tab or a separate switch.

    It may also be called: Vierasverkko (guest network), Guest network, Vierasverkko 2,4 GHz (guest network, 2.4 GHz), Guest WiFi

    If there is no guest network at all, this path does not suit your device. Move to the second router path, which makes the same separation.

  3. Give the network a name and a strong password

    The name can be anything, Home devices for instance. Make the password long: four random words in a row is plenty.

    It may also be called: SSID, Verkon nimi (network name), Salausavain (encryption key, password)

    Do not use the same password as your home network. Give the separate network its own name and password.

  4. Turn on client isolation, if it is offered

    This setting blocks direct connections between devices on the guest network. It may be beside the guest-network settings.

    It may also be called: Asiakaseristys (client isolation), AP isolation, Client isolation, Laite-eristys (device isolation)

    If the setting is not there, turn the guest network on anyway. It separates the devices from your computers even while they can see each other.

  5. Connect the smart devices to the new network

    Cameras, bulbs, plugs, the television and the vacuum. Computers and phones stay on the old network.

    It may also be called: Wi-Fi-asetukset (Wi-Fi settings), in the device's own app

    Some devices have to be reset before they ask for a network again. The instructions are in the device's own app, under network settings.

The ticks stay in this browser so you can carry on later. They are not sent anywhere.

How to check that it worked

What this does not protect against

It does not stop a device from sending data to the internet. Cloud recording and other online services still work. A guest network limits connections inside your home.

It does not fix the device's faults. If the manufacturer no longer updates the device, the holes are still in it.

It does not change the device's own functions. Separation only limits its connections to other devices in your home.

A guest network complements updates, unique passwords and account protection. It does not replace them.
