How to Set Up Guest Wi-Fi for Visitors
Handing out your main Wi-Fi password gives every guest device access to the same network as your computers, printers, and smart home devices. A guest network is a separate Wi-Fi network, just for visitors, that keeps your private devices apart from theirs.
Follow these steps
- Open the router’s admin page. From a device connected to your home network, open the router’s admin page using the address printed on the router, and log in with the admin details from the same label. The guest network setting is usually under wireless, Wi-Fi, or guest settings.
- Turn on the guest network. Enable the guest network option and give it a clear name, such as your home network name plus Guest. Keep the name friendly and recognisable so visitors can find it without asking twice.
- Set a simple but strong guest password. Choose a password that is easy to say out loud but hard to guess — a few random words work well. Avoid using your main Wi-Fi password, your address, or anything personal for the guest network.
- Make sure device isolation is on. Look for an option called AP isolation, client isolation, or “allow guests to see each other” and set it so guests cannot see each other or your devices. This is the setting that makes a guest network genuinely safer than just sharing your main password.
- Decide whether guests get full speed. Some routers let you limit guest speed or set a time limit. If your router offers it, a reasonable limit keeps a guest’s large download from slowing everyone else down, but it is optional — a simple guest network without limits is fine for most visits.
- Test it with your own phone. Connect your phone to the guest network and check that it reaches the internet but cannot see your printer or shared files. If it works, write the guest name and password on a small card for visitors, or just tell them when they arrive.
- Turn it off between visits, if you prefer. You can leave a guest network on all the time, but turning it off when nobody is visiting is a simple extra step. Either way, change the guest password occasionally, especially after a large gathering.
What NOT to do
- Do not give guests your main Wi-Fi password when a guest network is available.
- Do not leave a guest network open with no password — anyone nearby could use it.
- Do not reuse your main network’s password for the guest network; that defeats the separation.
- Do not assume a guest network is private for guests themselves on public-style networks; it separates them from your devices, not from the internet.
A guest network takes a few minutes to set up once, and then every visit is simpler: guests connect in seconds, and your own devices stay on their own private network.
