How to Remove Other Users from Your Wi-Fi: Safe Methods

Have you noticed that your internet speed has suddenly dropped, and unknown devices have appeared in the list of connected devices? Or perhaps your neighbors are downloading torrents through your Wi-Fi, wasting bandwidth and creating security risks? Removing unauthorized users from your home network is a task every router owner faces sooner or later. But how do you do it correctly, without disrupting your devices or creating security breaches?

In this article we will look at 5 working methodsto disconnect other people's devices from yours Wi-Fi: from a basic password change to advanced filtering settings MAC addressesYou'll learn how to identify "unwanted" devices, which router settings are responsible for security, and why some methods may be ineffective against experienced hackers. You'll also learn what to do if, after all these steps, unauthorized devices continue to connect.

Important: All instructions are provided for modern routers (TP-Link, ASUS, Keenetic, MikroTik etc.), but the interface and menu item names may differ slightly. If your model was released before 2018, some functions (e.g., guest network or time limit) may be absent.

1. How to detect other people's devices on your Wi-Fi network

Before blocking unauthorized users, you need to make sure they are actually connected to your router. Many people confuse neighboring networks with the same name or their own devices in standby mode (for example, smart speakers or IP cameras). Here's how to check the list of connected gadgets:

• 📱 Via the router's mobile app: most modern models (TP-Link Tether, ASUS Router, Keenetic) have mobile applications, where in the section Devices or Clients a full list of connected devices is displayed with an indication IP, MAC addresses and name.
• 🖥️ Via the router's web interface: enter in browser 192.168.0.1 or 192.168.1.1 (the address is indicated on the router sticker), log in and find the section DHCP, Local area network or Wireless Mode → Statistics.
• 🔍 Using third-party utilities: programs like Wireless Network Watcher (Windows) or Fing (Android/iOS) scan the network and show all connected devices, even if the router does not display them.

Please note unknown device names (For example, android-123456 or Unknown-Device), as well as on unusual activity: high traffic outside of business hours or connections made while you're away. If the list includes a device with the name of your old smartphone, which you haven't used in a while, this is also cause for concern: it could have been hacked and used as a "bridge" to access the network.

2. Method 1: Changing your Wi-Fi password is the fastest way

If you find any foreign devices, The first thing you need to do is change your Wi-Fi passwordThis will instantly disconnect all current users, including your own devices (they will have to be reconnected). This method is effective if:

• ✅ You don't use complex security settings (for example, WPA3-Enterprise).
• ✅ Outsiders connected after learning your password (for example, through neighbors or a leak).
• ❌ It won't help if the attacker has hacked the network through a router vulnerability or uses dictionary attack.

How to change your password:

1. Open the router's web interface (usually at 192.168.0.1 or 192.168.1.1).
2. Go to the section Wireless mode (or Wi-Fi → Security settings).
3. In the field Password (or Key, Passphrase) Enter a new key. It must be at least 12 characters long and include letters, numbers, and special characters (e.g., Green$Tree2026!WiFi).
4. Save the settings and reboot the router.

Important: after changing the password, all your devices (smartphones, laptops, Smart TV) will be disconnected. Prepare a list of gadgets that need to be reconnected in advance and check if they are using saved networks (for example, in Android this is a setting Auto-connection in the Wi-Fi settings).

3. Method 2: Blocking by MAC address - reliable, but not perfect

Filter by MAC address — is a method in which the router allows only devices with authorized identifiers onto the network. Each network device has a unique MAC (For example, 00:1A:2B:3C:4D:5E), which can be used for blocking or permissions.

How to set up filtering:

1. Find MAC addresses all your devices (they are specified in the network settings of each gadget or in the router's client list).
2. In the router's web interface, go to the section Wireless Mode → MAC Filter (or Access control).
3. Select mode Allow only specified (or Whitelist).
4. Add to list MAC addresses your devices and save the settings.

Advantages of the method:

• 🔒 Even if someone knows the Wi-Fi password, they won't be able to connect without permission MAC addresses.
• 📱 Convenient for monitoring family devices (for example, you can restrict access to children's gadgets).

Flaws:

• ⚠️ MAC addresses can be forged (spoofed), so the method does not protect against experienced hackers.
• ⚠️ When adding a new device (for example, a guest smartphone), you will have to manually update the list.

How to find the MAC address on different devices

Android: Settings → About phone → General information → Wi-Fi MAC address
iPhone/iPad: Settings → General → About → Wi-Fi Address
Windows: run the command ipconfig /all V CMD and find the line Physical address
MacOS: System Preferences → Network → Advanced → Ethernet/Wi-Fi → MAC Address

MAC addresses of some devices (e.g. smart bulbs Xiaomi or cameras Hikvision) may change after a firmware update. In this case, you will have to update the list of allowed addresses manually.

4. Method 3: Using a Guest Network to Isolate Devices

If you frequently provide Wi-Fi access to guests but don't want to risk your main network, set up guest network. This is a separate access point with its own name (SSID) and a password that:

• 🔐 Isolated from the main network (guests won't see your shared folders or printers).
• 🕒 May have a time limit (for example, access only from 10:00 to 22:00).
• 📶 Usually has a limited speed so as not to overload the main channel.

How to set up a guest network:

A guest network doesn't protect against hacking of your main Wi-Fi, but it does reduce the risk of your password being accidentally leaked. For example, you can allow guests to access only the internet, but not local devices (printers, NAS).

5. Method 4: Time and Bandwidth Limitation

If other devices connect in your absence (for example, at night), you can set up Wi-Fi operating schedule Or limit the speed for unknown devices. This won't remove them from the network, but it will render the connection useless.

How to set a time limit:

1. In the router's web interface, find the section Access control, Parental control or Wi-Fi schedule.
2. Add a rule to restrict (eg. Mon-Fri from 23:00 to 07:00).
3. Apply the rule to all devices or select specific ones MAC addresses.

How to limit speed:

• In the section QoS (or Bandwidth control) set a limit for unknown devices (for example, 1 Mbps).
• Use traffic prioritizationto ensure your devices always have an edge.

This method is useful if:

• 🕒 You want to block internet access at night (for example, to prevent children from using the internet after 10:00 PM).
• 📉 Third-party devices consume a lot of traffic (for example, for mining or torrents).

6. Method 5: Resetting the router to factory settings (last resort)

If you suspect that your router has been hacked (for example, its settings have been changed) DNS or DMZ), and other people's devices continue to connect despite all measures, it remains full resetThis will return the router to its out-of-the-box state, deleting all settings, including passwords and filtering rules.

How to reset a router:

1. Find the button on the back of the router. Reset (usually recessed into the body).
2. Press and hold it for 10-15 seconds (until the indicators start flashing).
3. After rebooting the router will have a standard IP address (usually 192.168.0.1 or 192.168.1.1), login admin and password admin (or empty password).
4. Please reconfigure your router. update the firmware and set a complex password.

⚠️ Attention: After resetting, all connected devices (including Smart TV, cameras, and smart plugs will lose network access. Prepare a list of gadgets that need to be reconnected in advance and check if they are tied to old settings (for example, some IoT devices require re-authorization after resetting the router).

Resetting helps in the following cases:

• 🔄 If the router is infected with malware (for example, through a firmware vulnerability).
• 🔧 If the security settings have been changed by an attacker (for example, disabled Firewall or changed DNS).

7. Additional security measures: how to prevent reconnection

Deleting other people's devices is half the battle. To prevent them from returning, follow these recommendations:

• 🔄 Update your router firmware regularly: Vulnerabilities in older versions are often exploited. Check for updates in the section System → Software Update.
• 🔒 Disable WPS: This feature simplifies connection, but has critical vulnerabilities. In the router settings, find WPS and deactivate it.
• 🌐 Use WPA3 instead of WPA2: The new encryption standard is harder to crack. If your router supports WPA3, select it in the security settings.
• 📡 Hide your SSID: Disable network name broadcasting in settings Wireless Mode → Hide SSIDThis won't protect you from experienced hackers, but it will reduce the number of accidental connections.

It's also worth checking if you're using vulnerable settings:

• 🚫 DMZ (demilitarized zone) should be disabled unless you have configured it specifically.
• 🚫 Remote control (access to the router from the Internet) must be disabled.
• 🚫 Router administrator password (admin) must be different from the Wi-Fi password.

⚠️ AttentionIf, after all these steps, other devices continue to appear on the network, your router may be compromised at the firmware level. In this case, it is recommended to replace it with a model that supports WPA3 and hardware Firewall (For example, ASUS RT-AX88U or Netgear Nighthawk).

8. Common mistakes and why other people's devices are returned

Many users encounter unauthorized devices reappearing online after being blocked. Errors to consider:

If none of the methods helped, there are two possible scenarios:

1. Your router has hardware vulnerability (for example, in models TP-Link Archer C50 There was a critical flaw in the release until 2019 UPnP). The solution is to replace the router.
2. Someone has physical access Someone (for example, neighbors or tenants) accesses your router and resets the settings. Solution: Move the router to an inaccessible location and enable notifications when someone logs in to the control panel.

FAQ: Answers to Frequently Asked Questions

Is it possible to remove someone else's device from Wi-Fi without changing the password?

Yes, but this is a temporary solution. You can:

• Block him by MAC address in the router settings.
• Limit speed to 1 kbps through QoS.
• Disable it manually in the section Devices (but after rebooting the router it will connect again).

However, without changing the password or other security measures, the device will be able to connect again.

Why do unknown gadgets with names like "android-xxxx" or "Unknown" appear in the list of devices?

These could be:

• Neighbors' devices if your Wi-Fi has a weak password or is turned on WPS.
• Your own gadgets in standby mode (eg. smart watch or fitness bracelets).
• Botnets if the router is infected with malware (check the settings) DNS).

Check first MAC addresses unknown devices - these may be your old devices.

How to protect your Wi-Fi from hacking if your neighbors know the password?

If someone you know (for example, previous tenants) might have found out your password, do the following:

1. Change your password to a complex one (≥12 characters, with letters, numbers and special characters).
2. Turn on WPA3 (if supported by the router).
3. Set up guest network for temporary access.
4. Turn it off WPS And Remote control.

If your neighbors continue to connect, consider the option with replacing the router for a model with improved protection (for example, ASUS RT-AX86U with support AiProtection).

What should I do if my router won't let me block my device by MAC address?

Possible causes and solutions:

• Your router has outdated firmware - update it.
• Filtering function MAC disabled - check settings Firewall.
• The router does not support filtering - use alternative methods (guest network, QoS).

If your router is older than 5 years, it may be time to consider a new model with modern security features.

Can other people's devices harm my network even if they are just connected?

Yes, there are risks:

• 🕵️ Traffic interception: if the network is not encrypted (WPA3), an attacker can see your passwords or data.
• 💻 Attacks on other devices: through a local network, it is possible to hack poorly protected gadgets (for example, IP cameras with default password).
• 📥 Traffic consumption: outsiders can download torrents or mine cryptocurrency, for which you will pay your provider.
• 🚫 Blocking your devices: Some viruses can send packets Deauth, disconnecting your gadgets from the network.

Therefore, it is important not only to remove other people's devices, but also monitor network activity (for example, through applications like GlassWire or Fing).
