How to Set Up a Guest WiFi Network

Updated: 2026-11-03 · 6 min read

Your guests need internet, not access to your laptop's shared folders, your printer or your baby monitor. A guest network gives them the first without the rest, and most routers sold in the last decade can create one in about five minutes.

Quick answer: To set up guest WiFi, log in to your router's app or admin page, open the Guest Network section, turn it on, give it its own name and a strong WPA2 or WPA3 password, and keep "access to local network" disabled. Save, connect a phone to test, then create a WiFi QR code for the guest network so visitors can join by scanning.

What a guest network does

A guest network is a second WiFi network broadcast by the same router. It shares your internet connection but is walled off from your main network. Typical protections:

That last point is underrated. When you rotate the guest password after a party, your smart TV, doorbell and laptops stay connected to the main network.

Before you start

You'll need:

Netgear (Nighthawk / Orbi)

ASUS

Open the ASUS Router app or router.asus.com, then Guest Network (or Guest Network Pro on newer firmware). Click Enable, choose a band, set the name and authentication method (WPA2-Personal or WPA3-Personal), set a key and set Access Intranet to Disable. ASUS also lets you set an access time limit, handy for short-stay visitors.

Google Nest WiFi / Google Home

In the Google Home app, open Wi-Fi > Settings > Guest network (location in the menu may vary by app version), create a name and password and choose which shared devices, such as a Chromecast, guests may see. Everything else on your network stays hidden.

Eero

In the eero app tap Settings > Guest Network, toggle it on, set the name and password, and save. Eero can show a shareable card for guests.

ISP-supplied routers (Jio, Airtel, BSNL, and others)

Many routers provided by internet companies include a guest or "multi-SSID" feature in the web admin page, often under WLAN, Wireless or Network > WiFi. Menus differ widely by model and firmware. If you can't find it, check your provider's app or support page. If the router truly lacks it, you can add your own router or mesh system behind it and create the guest network there.

Test the guest network

  1. Connect a phone to the guest network.
  2. Open a website to confirm internet works.
  3. Try to reach something on your main network, such as the router admin page or a shared printer. It should fail.
  4. Run a quick speed test to see how guests will experience it, especially from the guest room or garden.

Share it with a QR code

Now the fun part. Create a WiFi QR code for the guest network, not the main one. Your phone can do this: on Android 10+, connect to the guest network, open its settings and tap Share; on iOS 18+, use the Passwords app's Wi-Fi section. Or use a generator. On Android, Wifi QR Connect creates a WiFi QR code from the SSID, security type and password, and can also scan codes, share your hotspot by QR, run a download/upload speed test and show current connection info, with scan history stored locally on your device.

Then print the code. Our guides on making a WiFi QR code for guests and printable WiFi sign ideas cover sizing and design.

Maintaining your guest network

When a guest network isn't enough

Smart home devices are often the weakest part of a home network. Some people put cheap smart plugs and cameras on the guest network (or a separate IoT network) to keep them away from computers. That can work, but some devices need to be on the same network as your phone to set up or control them. Check the device's instructions before moving them.

A real-world example

Say you work from home and your in-laws visit for two weeks every winter. Before they arrive, you open the router app, enable "Sharma_Guest" with the password "Winter-Chai-Lamp-73", leave local access off and set no time limit. You print a QR card for the guest room. When they leave, you change the password to a new phrase and reprint the card for next time. Your laptop, printer and smart TV never notice, because they stay on the main network the whole time.

FAQ

Is a guest network slower than the main network?

It uses the same internet connection, so speed is similar unless you've set a bandwidth limit. Many routers let you cap guest speed so visitors don't slow down your work calls.

Can guests on the guest network see my devices?

Not when local network access is disabled, which is the default on most routers. Double-check the setting and test by trying to reach a shared printer or the router page.

Do I need a separate router for guest WiFi?

Usually not. Most modern routers and mesh systems have a guest network feature. Only very basic or older ISP routers lack it.

Should my guest network have a password?

Yes. A WPA2 or WPA3 password encrypts traffic and keeps strangers off your connection. A QR code makes the password easy for guests anyway.

How do I share the guest network easily?

Create a WiFi QR code for the guest network and keep it on a card inside your home. Visitors scan it with their phone camera and connect instantly.
