How to Disconnect Someone Else's Device from Your Wi-Fi on an ASUS Router: 4 Working Methods

Have you noticed that your Wi-Fi has slowed down, and unknown devices have appeared in the list of connected devices? Or has your neighbor "forgotten" your network password again and is actively using your data? Disconnect the unwanted user from ASUS router You can do it in just a few minutes—and you don’t need to be an IT specialist.

In this article we will look at all available blocking methods: from basic disabling via the web interface to advanced settings like MAC filtering or changing your password. We'll describe the nuances for popular models— RT-AX88U, RT-AC68U, TUF-AX3000 and others. We'll also explain why sometimes the device continues to connect even after being blocked and how to fix it.

Important: all methods work on firmware ASUSWRT (including ASUSWRT-Merlin), but the menu item layout may differ slightly. If you have a router from a provider with custom firmware (for example, Rostelecom or Beeline), some functions may be limited.

1. Method 1: Disabling the device via the router's web interface

The easiest and fastest method is to block a device directly from the control panel. This is suitable if you urgently need to cut off a user but don't want to change network settings.

To log in to the web interface:

• 🌐 Open your browser and enter in the address bar 192.168.1.1 (or router.asus.com).
• 🔑 Enter your login and password (default - admin/admin, if you haven't changed it).
• 📊 Go to the section Network map (or Network Map (in the English version).

Next:

1. Tab Clients (Clients) - all connected devices are displayed here.
2. Find the device you need in the list (use the name as a guide, MAC address or IP).
3. Click on the icon Block (or Block) next to the device.
4. Confirm the action - the device will be immediately disabled.

⚠️ Attention: Blocking via the web interface remains in effect until the router is rebooted. After the reboot, the device will be able to connect again if it knows the password.

Have you confused your device with someone else's? The device does not belong to a guest or family member. You have memorized the MAC address for permanent blocking. The router is not in "Guest Network" mode (there are different settings).

2. Go to Wireless network → MAC filter (Wireless → MAC Filter).
3. Enable the filter by selecting Turn on (Enable).
4. In the field Filter mode select Ban (Deny).
5. Enter MAC address devices (can be copied from the section Network map).
6. Save settings (Apply).

Now the device with the specified MAC address will not be able to connect to your network, even if it knows the password.

Where to find the MAC address on different devices

On Windows: open command prompt (Win + R → cmd → ipconfig /all) and find the line Physical address.

On Android: Settings → About phone → General information → Wi-Fi MAC address.

On iPhone/iPad: Settings → Wi-Fi → (i) next to the network → MAC address.

3. Method 3: Changing the Wi-Fi password (radical method)

If you don't want to mess around with MAC addresses, the most reliable way is to change your Wi-Fi passwordAll devices will be disconnected, and only those you give the new password to will be able to connect.

How to change your password:

1. Log into your router's web interface.
2. Go to Wireless network → General (Wireless → General).
3. In the field WPA Pre-Shared Key (WPA Pre-Shared Key) enter a new password.
4. Click Apply.

⚠️ Attention: After changing the password all devices (including yours) will be disabled. Prepare a list of devices that will require a new password in advance.

Once a month|Once every six months|Only when I notice suspicious devices|Never changed-->

Password recommendations:

• 🔐 Use at least 12 characters (numbers, letters, special characters).
• 🚫 Do not use personal information (dates of birth, names).
• 🔄 Change your password every 3-6 months.

4. Method 4: Using the ASUS Router app

If you find it inconvenient to configure your router via a browser, use the official app. ASUS Router (available for Android And iOS). It allows you to manage the network directly from your smartphone.

Instructions:

1. Download and install the application from App Store or Google Play.
2. Connect to the router network and log in to the application (login/password are the same as for the web interface).
3. Go to the section Clients (Clients).
4. Select the device and click Block (Block).

Advantages of the application:

• 📱 Convenient interface for mobile devices.
• 🔔 Notifications about new connections.
• 📊 Quick access to traffic statistics.

5. Why does the device continue to connect after being blocked?

Sometimes, even after blocking a device via a MAC filter or web interface, it reappears online. Causes and solutions:

If nothing helps, try:

• 🔄 Reset the router to factory settings (button Reset on the back panel).
• 🛡️ Turn on AiProtection (available on new models) - it automatically blocks suspicious devices.
• 📡 Change network name (SSID) — sometimes it helps to “knock down” automatic connections.

6. Additional security measures

To minimize the risk of unauthorized connections, configure your router according to these recommendations:

• 🔒 Disable WPS — This protocol is vulnerable to hacking. Find the option in Wireless Network → WPS and select Disable.
• 📶 Hide SSID (network name): in the Wi-Fi settings, enable the option Hide SSIDThen the network will not appear in the list of available ones, but you can connect to it if you know the name.
• 🔄 Update the firmware: go to Administration → Firmware Update and check if the version is up to date.
• 🕒 Set up a schedule: If you only need Wi-Fi during certain hours, limit access by time. Wireless Network → Schedule.

⚠️ Attention: Hiding the SSID does not make the network completely invisible - experienced users can detect it using special programs (for example, Wireshark or NetSpot). This is an additional measure, but not a panacea.

7. Common mistakes and how to avoid them

When blocking devices, users often make these mistakes:

• 🔄 They block their device by mistake. Always check the MAC address or device name before blocking.
• 🔑 Forget the new password after the shift. Write it down in a safe place (for example, in a password manager).
• 📡 They don't update the firmware, which is why vulnerabilities remain. Check for updates every 2-3 months.
• 🚫 Use simple passwords like 12345678 or qwertySuch combinations can be cracked in minutes.

If the device still connects after blocking, check:

• Is it connected to guest network (she has a separate password).
• Has it changed? MAC address devices (especially relevant for smartphones running Android 10+).
• Have the router settings been reset (for example, after a power outage)?

FAQ: Answers to Frequently Asked Questions

Is it possible to block a device by IP address?

Yes, but this is less secure than MAC blocking. IP addresses on the local network can change (if DHCP is enabled), so the device will receive a new IP and be able to connect again. To block by IP:

1. Go to Local Network → DHCP Server.
2. Find the device in the list of leased IPs.
3. Add his IP to Block list (if such an option is available in the firmware).

It is better to combine blocking by IP and MAC.

How do I know who is connected to my Wi-Fi?

There are several ways:

• Via the router's web interface: Network Map → Clients.
• Via the app ASUS Router (chapter Clients).
• Using third-party programs: Wireless Network Watcher (Windows), Fing (Android/iOS).

Watch out for unknown device names or unusually high traffic.

What should I do if my neighbor hacked my Wi-Fi?

If you suspect a hack:

1. Immediately change your password to complex (12+ characters).
2. Turn on MAC filtering and add only your devices to the list.
3. Turn it off WPS And remote control (V Administration → System).
4. Check your router for presence malware (reset to factory settings).

If the problem persists, consider purchasing a router with support. VPN servers (For example, ASUS RT-AX86U) for additional protection.

Is it possible to lock a device for a certain time?

Yes, ASUS routers have this feature. Access scheduleTo set up:

1. Go to Wireless Network → Schedule.
2. Add a new rule, specifying the days and hours to block.
3. Bind the rule to the device's MAC address.

This is convenient if you want to restrict access, for example, for children at night.

Why do other people's devices connect again after resetting the router?

When resetting to factory settings:

• Everything is erased MAC filtering rules.
• It is being restored default password (usually indicated on the router sticker).
• Additional security settings are disabled (for example, AiProtection).

After reset, be sure to:

1. Change your password to a new one.
2. Please reconfigure your MAC filter.
3. Disable WPS and remote control.
