How to Set Up a Guest WiFi Network
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.

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:
- Guests can't see your computers, NAS drives, printers, smart speakers or cameras.
- Guests often can't see each other (client isolation).
- Guests can't open the router's admin page.
- You can change or disable the guest password without disturbing your own devices.
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:
- Access to your router's app or web admin page. The address and default login are usually on the router label. Common addresses: 192.168.0.1, 192.168.1.1, 192.168.29.1 (some Jio routers) or a brand URL such as tplinkwifi.net or routerlogin.net.
- The admin password. If it's still the default, change it while you're there. This is different from the WiFi password.
- A phone to test the new network.
TP-Link (Deco app or web)
- Deco mesh: open the Deco app, tap More (or the menu) > Wi-Fi > Guest Network, switch it on, set a name and password, and save.
- Archer routers: open the Tether app or tplinkwifi.net, go to Advanced > Guest Network (on some models Wireless > Guest Network). Enable it for 2.4 GHz and/or 5 GHz, set the SSID and password, and leave "See each other and access my local network" unchecked.
Netgear (Nighthawk / Orbi)
- Nighthawk app or routerlogin.net: go to Guest Network (or Wi-Fi Settings > Guest Wi-Fi), enable it, set the name, choose WPA2 or WPA3, and set a password. Leave "Allow guests to see each other and access my local network" off.
- Orbi app: tap Wi-Fi > Guest Wi-Fi, turn it on and set the details.
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.
Recommended guest settings
- Name (SSID): clear and different from your main one, e.g. "Mehta_Guest". Don't include your flat number or full name if neighbours can see the network list.
- Security: WPA2/WPA3 mixed (transition) mode is the friendliest. WPA3-only can lock out older phones and laptops. Compare in WPA2 vs WPA3: What to Pick in Your QR Code.
- Password: 12+ characters. Something memorable for laptop users, like "Teal-Kettle-Garden-58".
- Local network access: off.
- Client isolation: on, if offered.
- Bands: enable both 2.4 GHz (range) and 5 GHz (speed), or let a mesh system handle it automatically.
- Bandwidth limit / schedule: optional, useful in rentals and small offices.
- Hide SSID: not needed and usually makes things harder; see Hidden Network WiFi QR Code: How It Works.
Test the guest network
- Connect a phone to the guest network.
- Open a website to confirm internet works.
- Try to reach something on your main network, such as the router admin page or a shared printer. It should fail.
- 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
- Rotate the password every few months, or after big gatherings or long-term guests. Follow How to Change Your WiFi Password and Update QR Codes.
- Update router firmware. Security fixes often arrive through updates; many routers can update automatically.
- Check connected devices in the router app occasionally. Unknown devices on the guest network are a signal to change the password.
- Turn it off if you rarely have visitors; you can switch it back on in seconds.
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.
