How to Limit Wi-Fi Users: A Complete Guide for 2026 Routers

Have you noticed your Wi-Fi has slowed down, and unknown devices are appearing in the list of connected devices? Or perhaps you want to share the internet with guests, but are afraid they'll reveal the password to all their friends? Limiting the number of Wi-Fi users solves both problems: it protects the network from overload and prevents unauthorized connections. In this article, we'll explore these options. 5 working methods Set up device limits - from basic router functions to advanced methods using MAC filtering And guest networks.

It's important to understand that not all routers support direct connection limit settings. For example, budget models Tenda or D-Link often lack this option, while flagship ASUS RT-AX88U or Keenetic Ultra offer flexible tools. We'll look at universal solutions that work on 90% of modern devices, as well as alternatives for stubborn cases. If your router model is older than 2018, Check for DD-WRT or OpenWRT firmware support—they add a limiting feature even to weak hardware..

1. Restriction via the router's web interface (the easiest way)

Most modern routers allow you to set the maximum number of connected devices directly in the control panel. This method requires no technical knowledge and takes less than 5 minutes. Let's look at the process using popular brands as examples.

To get started, connect to your router via cable or Wi-Fi. Enter the device's IP address (usually 192.168.0.1, 192.168.1.1 or 192.168.8.1). The default login and password are indicated on the sticker on the back of the case (most often admin/admin).

• 🔧 TP-Link (Archer, Deco): Go to Advanced Settings → Wireless → Wireless SettingsFind the option Maximum number of clients and set the desired value (for example, 10).
• 🖥️ ASUS (RT-AX, RT-AC): Open Wireless Network → General and find the field Limit of wireless clientsIn some firmware versions the option is hidden in Professional settings.
• 🌐 Keenetic: On the menu Home Network → Wi-Fi Segment Select your network and turn on the switch Limit the number of clients.
• ⚡ Zyxel Keenetic: Path: Wi-Fi → Access Point → Additional SettingsThe option is called Max. number of clients.

After saving the settings, the router will automatically turn off unnecessary devices on a first-come, last-served basis. Please note: some models (e.g., Mercusys) reset the restriction after a reboot. In this case, you'll have to use alternative methods.

⚠️ Attention: On routers with firmware from the provider (for example, Rostelecom or Beeline) The restriction option may be blocked. In this case, request access to advanced settings from your operator or use the methods in the following sections.

2. MAC filtering: how to allow connections only to certain devices

If you need to not just limit the number of users, but prohibit connection of specific gadgets (for example, neighbors' smartphones), use MAC filteringThis method works on all routers, but requires manual entry of device addresses.

A MAC address is a unique identifier for a network card and looks like this: 00:1A:2B:3C:4D:5EYou can find out about it:

• 📱 On Android: Settings → About phone → General information → Wi-Fi MAC address.
• 🍎 On iPhone/iPad: Settings → Wi-Fi → (i) next to the connected network.
• 💻 On Windows: run the command in CMD:

  ipconfig /all | findstr "Physical Address"

• 🖥️ On MacOS: System Preferences → Network → Advanced → Ethernet/Wi-Fi.

Now add the allowed MAC addresses to the router:

1. Go to the router's web interface (as in the previous section).
2. Find the section MAC filter (may be called Access control, Wireless MAC Filtering).
3. Select mode Allow only specified devices (Allow).
4. Enter MAC addresses separated by commas or add them one by one.
5. Save the settings and reboot the router.

The downside of this method: if you buy a new gadget, you'll have to add its MAC address manually. However, this is the only way to 100% block other people's devices, even if they know your Wi-Fi password.

3. Guest network: separate Wi-Fi with user limits

If you often have guests over but don't want them to connect all their devices to the main network, set up guest networkIt works in parallel with the main one, but has a separate password and restrictions.

Benefits of a guest network:

• 🔒 Isolation from the main network (guests won't see your shared folders or printers).
• ⏱️ Possibility to set a time limit (for example, 2 hours).
• 📶 Speed ​​limit (to prevent guests from “eating up” all the traffic).
• 👥 Limit on the number of devices (usually 5–10).

Instructions for popular routers:

In the guest network you can also limit bandwidth (for example, up to 10 Mbps) so that the main devices don't suffer from the load. The setting is available in the section Qos or Bandwidth control.

4. Use Parental Controls to Restrict Devices

If your router does not support direct user limit setting, you can bypass this limitation using parental controlThis method allows you to not only limit the number of devices but also set a schedule for their operation (for example, turning off children's gadgets after 10:00 PM).

Algorithm of actions:

1. Log into your router's web interface.
2. Find the section Parental control (or Access Control, Parental Controls).
3. Add all devices to the “blacklist” except those allowed (by MAC address or IP).
4. Set the rule: Block all devices except those specified.
5. Save the settings and reboot the router.

On routers ASUS And Netgear there is an option Time Scheduling, which allows you to restrict access by time. For example, you can allow only 5 devices to connect between 9:00 AM and 6:00 PM. This is useful for offices or cafes where Wi-Fi should only be available during business hours.

What if parental controls don't block devices?

Check that the DHCP server is enabled on your router (it should assign IP addresses automatically). If the device has a static IP, the parental control rule may not work. Also, make sure the router's time is synchronized with the internet (an incorrect time will disrupt the blocking schedule).

The downside of this method: parental controls don't directly limit the number of devices, but only block unauthorized ones. If someone connects a new device, it won't be able to access the network, but there won't be an error—it simply won't receive an IP address.

5. Advanced Method: Limiting via DD-WRT or OpenWRT Firmware

If your router does not support the required features out of the box, install alternative firmware. DD-WRT or OpenWRTThese systems provide access to advanced settings, including limiting the number of clients per SSID.

Warning: Reflashing your router may void your warranty or cause the device to malfunction. Only attempt this if you are confident in your abilities or have a spare router.

Instructions for DD-WRT:

1. Install the firmware (instructions are available on the official website) dd-wrt.com).
2. Go to the web interface (192.168.1.1).
3. Go to Wireless → Basic Settings.
4. Find the option Max Associated Clients and set the desired value.
5. Save settings (Apply Settings).

For OpenWRT you will need to edit the configuration file /etc/config/wireless via SSH. Add the line:

option maxassoc '10'

Where 10 — maximum number of devices.

⚠️ Attention: After installing alternative firmware, some features (such as IPTV or Dual Band) may no longer be supported. Before updating, check the compatibility of your model on the forums. 4PDA or OpenWRT.

6. Restriction via the provider's mobile application

If your router is provided by your internet service provider (e.g. Rostelecom, MTS or Beeline), it may have a proprietary mobile app with simplified controls. These apps often have options not available in the web interface.

Application examples:

• 📱 Rostelecom: "My Account" app → "Wi-Fi" section → "Device Management." Here you can see all connected devices and block unnecessary ones.
• 📲 MTS: My MTS app → Wi-Fi Settings → Device List. There's an option to "Restrict new connections."
• 🌐 Beeline: My Beeline app → Internet → Wi-Fi settings. You can set the limit manually.

The advantage of this method is its simplicity and the lack of risk of damaging the router. The disadvantage: not all providers offer such options, and the apps' functionality is often limited.

⚠️ Attention: Provider apps sometimes have bugs that cause restrictions to reset after an update. Check your settings regularly if you notice any suspicious activity on the network.

7. Additional measures: how to protect Wi-Fi from unauthorized access

Limiting the number of users is good, but even better prevent other people's devices from connectingHere are some tips:

• 🔐 Change the default password: Use a complex password of 12+ characters, including numbers and special characters. Do not use your birthday or the word "password."
• 🔄 Disable WPS: This feature simplifies connection, but makes the network vulnerable to hacking. Disable it in your router settings.
• 📡 Hide SSID: In the Wi-Fi settings, disable the "Broadcast SSID" option. Your network will not appear in the list of available networks, but you can connect to it manually.
• 🔄 Update firmware: Manufacturers regularly patch vulnerabilities. Check for updates every three months.
• 🛡️ Use WPA3: If the router supports WPA3, enable it instead of the outdated one WPA2.

Also useful keep a connection logMost routers have a section Logs or System log, which displays all connection attempts. If you notice any unknown MAC addresses, block them immediately.

FAQ: Frequently asked questions about Wi-Fi user restrictions

Is it possible to limit the number of users on Wi-Fi without access to the router?

No, all restriction settings are configured at the router level. If you don't have access to the router's control panel (for example, in an office or public place), contact your network administrator. An alternative option is to use personal VPN on their devices, but this will not limit other users.

What should I do if my router doesn't support user restrictions?

There are several options:

1. Buy a router that supports this feature (for example, ASUS RT-AX55 or TP-Link Archer AX21).
2. Install alternative firmware (DD-WRT, OpenWRT).
3. Use MAC filtering or guest network as an alternative.
4. Connect the second router in mode access points with separate settings.

How do I know how many devices are connected to my Wi-Fi?

Verification methods:

• Via the router's web interface: section DHCP clients, List of devices or Wireless Clients.
• Via the provider's mobile app (if available).
• Using network scanning programs: Fing (Android/iOS), Wireless Network Watcher (Windows).

If you see unknown devices, block them immediately by MAC address.

Is it possible to limit the speed for certain devices?

Yes, this is done through a function QoS (Quality of Service) in the router. For example, on ASUS path: Adaptive QoS → BandwidthHere you can set limits for each device by MAC address or IP. Also, some routers (for example, Keenetic) allow you to limit the speed in the guest network.

Why did Wi-Fi become slower after limiting users?

Possible reasons:

• The router is overloaded due to a large number of connection requests. Try reducing the limit or rebooting the device.
• Feature enabled MAC filtering, which creates an additional load on the router's processor.
• The guest network uses the same frequency as the main network, causing interference. Try separating the networks into different channels (2.4 GHz and 5 GHz).

If the problem persists, reset your router to factory settings and reconfigure the restrictions.
