Guest Wi-Fi network on a router TP-Link Archer — This isn't just a courtesy to visitors, but a fully-fledged security tool. It allows you to separate your primary home or office traffic from temporary connections, protecting your personal data from accidental access. For example, if you share your Wi-Fi password with friends, tenants, or clients, they'll be able to use the internet but won't be able to see devices on your local network (printers, NAS, smart speakers).
In this article, we'll look at how to set up a guest network on popular models. Archer (C6, C7, C20, AX10, AX20 and others) via web interface, mobile application TetherWe'll also provide recommendations for optimizing speed and security. We'll also pay special attention to common errors that can prevent the guest network from working and how to fix them.
If you've never accessed your router's control panel before, don't worry. This guide is suitable even for beginners: all steps are illustrated with screenshots of the latest firmware (2026), and we'll explain complex terms in simple terms. Setup will take no more than 10 minutes!
Why do you need a guest Wi-Fi network and how is it different from your main network?
Many users mistakenly believe that a guest network is simply a “second Wi-Fi with a different password.” In fact, it has three key differences, which make it indispensable:
- 🔒 Device isolation: Guests won't see your computers, printers, or IP cameras on the local network. This protects against accidental access to shared folders or smart devices (e.g. Xiaomi Home or Google Nest).
- 📶 Speed Limit: You can allocate only a portion of the channel to guests (for example, 20 Mbps out of 100 Mbps) so that they do not “clog up” the Internet for the main users.
- ⏱️ Time restrictions: On some models Archer (for example, AX50) you can set up automatic shutdown of the guest network according to a schedule (for example, from 23:00 to 7:00).
Additionally, a guest network is useful in the following scenarios:
- 🏠 Renting a houseAre you renting out your apartment by the day? Give tenants access only to the guest network so they don't connect to your smart light bulbs or security systems.
- ☕ Cafes/hotelsProvide Wi-Fi to your customers without the risk of them accessing your POS terminals or reservation system.
- 🎮 Game consoles: If you have PlayStation or XboxFor users who frequently connect to random networks (such as those in hotels), a guest network will protect your main devices from potential console vulnerabilities.
⚠️ Note: On some older firmware versions TP-Link The guest network has the same defaultSSID, the same as the main one, but with a suffix_GuestThis can cause confusion among devices (especially Android-smartphones) that automatically connect to "familiar" networks. We recommend setting a unique name, for exampleCafe_Free_WiFi.
Preparing for Setup: What to Check Before Creating a Guest Network
Before you move on to the settings, make sure your router is ready to create a guest network. Here 4 critical moments, which are often missed:
- Firmware update: Outdated software may not support guest networks or may contain vulnerabilities. Check the latest version in
Settings → System Tools → Firmware Update. - Free range: If you have a dual-band router (2.4 GHz + 5 GHz), decide which band your guest network will operate on. 5 GHz faster, but has a smaller coverage area.
- DHCP IP pool: Make sure that in the settings
DHCPenough free IP addresses for guest devices (the default is usually enough, but if you have a lot of equipment, check the range inNetwork → LAN). - Administrator password: Go to your router control panel (
192.168.0.1or192.168.1.1) and change the default login/password (admin/admin) so that no one can change the guest network settings.
Also pay attention to router operating modeIf it is configured as Repeater (repeater) or Bridge, the guest network may not work. In this case, first switch to the mode Wireless router (Settings → Operating Mode).
Step-by-step setup of a guest network via the web interface
The most reliable way to set up a guest network is through your router's control panel. These instructions apply to all modern models. Archer (including AX series). If you have an older firmware, some menu items may be slightly different.
Step 1. Login to the control panel
Open your browser and type in the address bar 192.168.0.1 or 192.168.1.1 (Look at the sticker on the bottom of the router). Enter your login and password (default admin for both fields, if you haven't changed them). If you can't log in, reset the router using the button Reset (hold for 10 seconds).
Step 2: Go to the Guest Network section
In the new interface TP-Link (blue design) the path is:
Additional settings → Guest network
In the old interface (green design):
Wireless Mode → Guest Network Settings
Step 3. Setting up basic parameters
A form with settings will open. Fill it out as follows:
| Parameter | Recommended value | Explanation |
|---|---|---|
Enable guest network |
✅ Included | Activates the function. Without checking the box, the settings will not be saved. |
Network name (SSID) |
Guest_WiFi_5G (example) |
Don't use the main network name! Add a suffix. _Guest or _Free. |
Security |
WPA2-PSK (or WPA3-PSK, if supported) |
WEP unsafe, Open network - risky. |
Password |
Minimum 8 characters, with numbers and letters | Do not use the main network password. Example: Cafe123!Free |
Isolate guest users |
✅ Included | Prevents devices on the guest network from "seeing" each other. |
Step 4. Speed limit (optional)
If you want to limit the speed for guests, find the section Bandwidth control (or QoS) and set limits. For example:
- 📥 Incoming speed (Download): 20 Mbit/s (if your tariff is 100 Mbit/s).
- 📤 Upload speed: 5 Mbps.
Step 5. Saving settings
Click Save, then Reboot (if necessary). The guest network will appear in the list of available Wi-Fi networks within 1–2 minutes.
Is the "Enable Guest Network" checkbox checked?
Is a unique SSID specified (not the same as the main network)?
Is a secure encryption type selected (WPA2/WPA3)|
Is the password set to be at least 8 characters long?
Is the "Isolate Guest Users" option enabled?

Setting up a guest network using the Tether mobile app
If you prefer to control your router from your smartphone, use the official app. TP-Link Tether (available for Android And iOS). The interface there is more intuitive, but the functionality is slightly limited compared to the web version.
Step 1: Connecting to the Router
Download Tether from App Store or Google Play, open it and select your router from the list. The app will automatically detect the model (for example, Archer C6) and will ask for the administrator password.
Step 2: Go to the Guest Network section
Tap the router icon → Additionally → Guest networkIn some versions of the application the path may look like this Wi-Fi Settings → Guest Network.
Step 3. Filling in the parameters
Here everything is similar to the web interface, but with simplified settings:
- 🔄 Range: Select
2.4Gor5G(if the router is dual-band). - 🔐 Security: Leave
WPA2-PSK(V Tether NoWPA3for the guest network). - ⏳ Opening hours: You can set a schedule (for example, from 9:00 to 22:00).
Step 4. Saving and checking
Click Save and wait for the router to reboot. The guest network will appear in the Wi-Fi list on your smartphone. To make sure everything is working, connect to it and try opening a website (for example, speedtest.net).
⚠️ Attention: In the attachment Tether there is no possibility to configure isolation of devices on a guest network. If this setting is critical (for example, for a cafe or hotel), use the web interface!
Common errors and how to fix them
Even after proper configuration, the guest network may not work. Here 5 most common problems and ways to solve them:
- 🔌 Guest network does not appear in the Wi-Fi list
Cause: Channel conflict or disabled function in settings.
Solution:- Check if the checkbox is enabled
Enable guest network. - Change the channel in the main Wi-Fi settings (for example, from
Autoon6or11). - Reboot the router using the button
Power(NotReset!).
- Check if the checkbox is enabled
- 🔒 Devices do not connect to the guest network
Cause: Incorrect password or encryption type.
Solution:- Make sure your password does not contain Cyrillic characters (use only
A-Z, a-z, 0-9, !@#$%). - Try changing the security type from
WPA2onWPA/WPA2(universal mode).
- Make sure your password does not contain Cyrillic characters (use only
Cause: Incorrect settings
DHCP or blocking MAC filter.Solution:
- Check that in
Network → DHCPThe server is turned on and there are enough IP addresses. - Turn it off
MAC filteringVWireless Mode → MAC Filtering. - 🕒 Working hoursSet up automatic shutdown of the guest network at night (for example, from 12:00 AM to 6:00 AM). This will protect against unauthorized access when you're away. Path:
Advanced Settings → Guest Network → Schedule. - 📊 Traffic limitation: In sections
QoSorBandwidth controlYou can set limits on speed or total data volume (useful for tariffs with limited traffic). - 🔍 Connection log: Enable connection logging (
System Tools → Log) to see which devices were using the guest network. - 🔄 VLAN for guest network: On advanced models (for example, Archer C5400) you can separate guest traffic into a separate
VLAN, completely isolating it from the main network at the port level.
If the problem is not solved, try reset the router to factory settings (button Reset for 10 seconds) and set up the guest network again. This helps in 90% of cases.
What to do if the guest network works, but is very slow?
The most common reason is channel congestion in the 2.4 GHz band. Try the following:
1. Switch the guest network to 5 GHz (if the router supports it).
2. Reduce the channel width with 40 MHz to 20 MHz in the Wi-Fi settings.
3. Limit the speed for guest devices in QoS (for example, up to 10 Mbps).
4. Check if there are too many devices connected to the guest network (optimally no more than 10).
Additional settings for security and convenience
A basic guest network setup is usually sufficient, but for increased security and traffic control you can use advanced features:
If you have a router that supports IEEE 802.11k/v/r (For example, Archer AX6000), enable these options in your Wi-Fi settings. They will improve roaming between the guest and primary networks for devices that frequently switch (such as smartphones).
Comparing guest networks on different TP-Link Archer models
Not all routers Archer Guest network support is identical. The table below shows the key differences between popular models:
| Model | 5 GHz support | Device isolation | Speed Limit | Schedule |
|---|---|---|---|---|
| Archer C6 | ❌ No | ✅ Yes | ✅ Yes (via QoS) | ✅ Yes |
| Archer C7 | ✅ Yes | ✅ Yes | ✅ Yes | ✅ Yes |
| Archer AX10 | ✅ Yes (Wi-Fi 6) | ✅ Yes | ❌ No (manual mode only) | ✅ Yes |
| Archer C20 | ❌ No | ✅ Yes | ✅ Yes | ❌ No |
| Archer AX6000 | ✅ Yes (three ranges) | ✅ Yes (with VLAN) | ✅ Yes (flexible rules) | ✅ Yes |
On routers of the series AX (Wi-Fi 6) guest network can operate in mode OFDMA, which improves performance when a large number of devices are connected (for example, in an office or cafe). However, to do this you need to enable AX mode in the wireless network settings.
⚠️ Please note: On some models (eg. Archer C50) the guest network in the 5 GHz range may conflict with the main network if enabledSmart ConnectIn this case, turn it off.Smart ConnectVWireless Mode → Smart Connect Settings.
FAQ: Frequently Asked Questions about Guest Networking on TP-Link Archer
Is it possible to give the guest network the same password as the main one?
Technically it is possible, but highly not recommendedIf a guest discovers the password, they can connect to the main network, bypassing all restrictions. Use different passwords, at least 8 characters long, with numbers and special characters.
Why is the guest network slower than the main network?
This is normal if you have set the speed limit in QoSThe cause may also be:
- 2.4GHz channel is congested (switch to 5GHz).
- Weak signal (check the location of the router).
- Outdated firmware (update router software).
Is it possible to create a guest network without a password?
Yes, but this unsafeIn this case, anyone can connect to your network, consume traffic, and potentially attack other devices. If you need an open network (for example, for a cafe), use captive portal with authorization via social networks or SMS.
How do I find out who is connected to the guest network?
Go to Wireless Mode → Wireless Mode Statistics or DHCP → Client ListThere will be a list of all connected devices with their MAC addresses and IP. To block a suspicious device, add it MAC blacklisted (Wireless Mode → MAC Filtering).
The guest network is working, but I can't access some websites. What's wrong?
Probably included parental control or content filtering. Check:
Additional settings → Parental controls.Security → URL Filtering.
Disable restrictions or add blocked websites to the whitelist.
