Noticed an unknown device in the list of connected gadgets? Or want to restrict access to your network for older devices? Removing devices from Wi-Fi — a simple but important procedure for router security and optimization. In this article, we'll cover all the current methods: from manual deletion via the web interface to automatic blocking by MAC address.
Many users mistakenly believe that simply turning off a device will remove it from the list of connected devices. In fact, the router saves information Gadgets are cached, and some models even reserve IP addresses for them via DHCP. This can lead to IP conflicts, network slowdowns, or security vulnerabilities. Below, you'll learn how to completely "wipe" a device from your router's memory and why this is sometimes insufficient.
If you've never accessed your router settings before, don't worry. We'll walk you through the process for popular models (TP-Link Archer C6, ASUS RT-AX88U, Keenetic Giga) and universal methods that work on 90% of devices. And for those who prefer mobile solutions, there's a separate section on network management via apps like Tether or Mi Wi-Fi.
1. How to check the list of connected devices
Before deleting anything, you need to understand exactly which devices are connected to your network. This list will help you identify "unnecessary" devices—for example, neighbors who connected by mistake, or old smartphones that haven't been used for a while but are still using an IP address.
The list of active connections can be viewed in three ways:
- 🖥️ Through router web interface (the most reliable method)
- 📱 In mobile application manufacturer (convenient, but not all models are supported)
- 🔍 With the help of third-party utilities like Fing or WiFi Analyzer (shows only active devices)
To access the web interface, enter one of the standard IP addresses in the browser's address bar:
192.168.0.1, 192.168.1.1 or 192.168.8.1The default login and password are usually indicated on the router sticker (most often this is admin/admin or admin/password). In the menu, look for sections like DHCP Clients List, Connected Devices or Local area network.
Please note the columns with MAC address And IP address — this data will be useful for deletion. If the list contains a device with an unfamiliar name (for example, android-12345678 or esp_abcdef), it could be a smart light bulb, a camera, or someone else's gadget. MAC addresses in the format 00:1A:2B:... often belong to Apple devices, while addresses with the prefix 78:31:C1 belong to Xiaomi gadgets.
2. Removing devices via the router's web interface
This is the most reliable method, which works on all modern routers. Instructions may vary slightly depending on the model, but the general procedure is the same. Let's look at the process using popular brands as examples.
General plan of action:
- Log in to the router's web interface.
- Go to the section with a list of connected devices (names may differ).
- Find the desired device by name or MAC address.
- Click the button
Delete,BlockorDisconnect. - Save the settings (if required).
For specific models:
- 🔹 TP-Link:
Advanced → Statistics → DHCP Clients List→ select device →Remove - 🔹 ASUS:
Local Network → DHCP Client List→ click on the trash can icon - 🔹 Keenetic:
Devices → Device List→ click on the device →Forget - 🔹 MikroTik:
IP → DHCP Server → Leases→ select the line →Remove
Check the name and MAC address of the target device|
Make sure it is not currently in use|
Remember or write down the IP address (useful for blocking)|
Check if there is a MAC binding in the router settings-->
Important: Some routers (eg. Zyxel Keenetic) don't completely remove the device, but only break the current connection. To prevent the gadget from reconnecting, you need to add its MAC address to blacklist (more on this in the next section).
⚠️ Attention: If you are deleting a device that was connected viaWi-Fi DirectorWPS, its data may remain in a separate list. For example, on routers ASUS you need to go toWireless Network → WPSand manually clear the connection history.
3. Blocking devices by MAC address (blacklist)
Removing a device from the list of connected devices does not guarantee that it will not connect again. If necessary permanently block access For a specific device (for example, someone else's smartphone or a neighbor's smart speaker), add its MAC address to the blacklist.
How does this work:
- 🛡️ The router checks the MAC address of each device when attempting to connect.
- 🚫 If the address is on the blacklist, access is blocked at the network level.
- 🔄 The list is valid until the router is reset.
Instructions for popular routers:
| Brand | Path to settings | Action |
|---|---|---|
| TP-Link | Advanced → Security → Access Control |
Add MAC to the list Blocked Devices |
| ASUS | Local Network → Route → Access Control List |
Select Ban and specify the MAC |
| Keenetic | Devices → MAC Address Filter |
Create a rule with an action Block |
| D-Link | Advanced → MAC Filter |
Activate the filter and add the address to Deny |
Please note: On some routers (MikroTik, Ubiquiti) the blacklist is configured via FirewallFor example, in MikroTik you need to create a rule:
/ip firewall filter add chain=forward mac-protocol=ipv4 src-mac-address=00:1A:2B:3C:4D:5E action=drop⚠️ Please note: MAC addresses can be spoofed, so this method does not provide 100% protection. For critical networks, use additional measures, such as isolation of clients (AP Isolation) or guest network.
4. Removing devices via mobile apps
If accessing your router settings through a browser is inconvenient, you can use the manufacturer's official apps. They typically offer a simplified interface and notifications about new connections.
Popular Wi-Fi management apps:
- 📱 Tether (for routers TP-Link)
- 📱 ASUS Router (for devices ASUS)
- 📱 Mi Wi-Fi (for routers Xiaomi)
- 📱 Keenetic (universal for all models of the brand)
For example, in Tether the algorithm is as follows:
- Open the app and connect to your router.
- Go to the tab
Devices(orClients). - Find the device you need and swipe left (or tap the three dots).
- Select
DeleteorBlock.
IN Mi Wi-Fi there is an additional option Limit the speed — useful if you don't want to completely block a device, but just reduce its impact on the network. For example, you can restrict a smart camera that constantly uploads video to the cloud.
5. Clear DHCP leases and router cache
Even after a device is removed from the list, its IP address may remain reserved in DHCP poolThis causes the router to continue to "remember" the device and may assign it the same IP address the next time it connects. To completely reset this information, you need to clear the DHCP cache.
How to reset a DHCP lease:
- 🔄 On TP-Link:
Advanced → Network → DHCP Server→ clickRenewor reboot the router. - 🔄 On ASUS:
Local Network → DHCP Server→ buttonClear rental list. - 🔄 On Keenetic:
Internet → Local Network → DHCP Settings→Clear cache.
If your router does not have this option, you can do soft reset:
- Go to
System Tools(orAdministration). - Select
Reboot(reboot). - After rebooting, the DHCP cache will be cleared automatically.
What happens if you don't clear the DHCP cache?
If you don't reset the DHCP lease, the router may continue to reserve IP addresses for devices that haven't connected in a while. This leads to:
- Slowing down the issuance of IP addresses to new devices (the router has to "think" for a long time).
- IP conflicts if two devices receive the same address.
- Problems with connecting smart devices (lamps, cameras) that expect a specific IP.
For advanced users: If you need to manually manage IP allocation, you can assign addresses to specific devices (DHCP Reservation). For example, ASUS this is done in Local Network → DHCP Server → ReservationThis way, your smartphone will always receive the same IP address, while unknown devices will not.
6. Additional security measures after removal
Removing a device from the network is only the first step. To prevent unwanted devices from reconnecting, we recommend the following:
List of measures to protect Wi-Fi:
- 🔒 Change your Wi-Fi password (use
WPA3, if the router supports it). - 🔄 Disable WPS - This protocol is vulnerable to brute force attacks.
- 📡 Enable client isolation (AP Isolation) so that devices cannot see each other.
- 🛡️ Set up a guest network for temporary connections (e.g. for guests).
- 🔍 Turn on notifications for new devices in the mobile application.
How to change your Wi-Fi password: An example Keenetic:
- Go to
Wi-Fi network → Access point. - In the field
Network keyEnter a new password (at least 12 characters, including numbers and special characters). - Select the security type
WPA3-Personal(orWPA2/WPA3for compatibility). - Save the settings and reconnect all devices.
For maximum safety, you can also disable broadcast SSID (hide the network name). This way, only those who know the exact Wi-Fi name will be able to connect. However, this method doesn't protect against experienced hackers who can find the hidden network using specialized software.
⚠️ Warning: If you use Mesh system (For example, TP-Link Deco or Google Nest Wi-Fi), security settings must be applied on the primary router. Secondary nodes synchronize settings automatically, but sometimes a reboot of the entire system is required.
7. Common mistakes and how to avoid them
When removing devices from a Wi-Fi network, users often encounter common issues. Let's look at the most common ones and how to solve them.
Top 5 Bugs and Fixes:
| Problem | Cause | Solution |
|---|---|---|
| The device reappears after deletion. | DHCP cache not cleared or MAC not added to blacklist | Reset the DHCP lease and block the MAC address |
| I can't find the device in the list | The gadget is connected via cable (LAN) or disconnected | Check the section Local Area Network → ARP Table |
| After deleting, the Internet disappeared on all devices. | DHCP server failure | Reboot your router or reset DHCP settings |
| I can't access my router settings. | The gateway IP address has been changed or the web interface has been disabled. | Reset the router using the button Reset (hold for 10 seconds) |
| Smart devices (lamps, cameras) do not connect after changing the password | They remembered old Wi-Fi data | Reset your smart device and reconnect it |
If after all these steps the unknown device continues to appear on the network, this may indicate:
- 🕵️ Password leak (someone connects deliberately).
- 🤖 Infected device on your network (virus or botnet).
- 📡 Problems with the router (firmware failure or hardware malfunction).
In such cases we recommend:
- Check all connected devices for viruses (especially Windows PCs and Android smartphones).
- Update your router firmware to the latest version.
- Temporarily change the network name (SSID) and password to "reset" all connections.
FAQ: Answers to Frequently Asked Questions
Is it possible to remove a device from Wi-Fi without going into the router settings?
Yes, but with limitations. Some routers (for example, ASUS or Netgear) allow you to manage connections through a mobile app. You can also use third-party utilities such as Fing to break the connection, but this is a temporary measure - the device will be able to connect again.
Permanent deletion will still require access to the router's web interface or app.
How do I delete a device if I don't know the router password?
If you have forgotten your router password, you have two options:
- Factory reset: press and hold the button
Reseton the router for 10-15 seconds. After that, the login and password will be reset to the default (usuallyadmin/admin). - View the password on the sticker: Login information is often located on the bottom of the router.
Please note: Factory reset will erase all your settings, including your Wi-Fi name and network password.
Why does the device still connect after I remove it?
This happens because:
- You removed the device from the list of active connections, but did not block it. MAC address.
- The router didn't clear DHCP cache and assigned the same IP again.
- The device is connected via another protocol (for example, via WPS or Wi-Fi Direct).
Solution: Add the MAC address to the blacklist, reset the DHCP lease, and check the WPS settings.
Is it possible to delete a device by IP address?
Yes, but it's less secure than MAC blocking. IP addresses can change (unless they're statically assigned), while a MAC address is permanently tied to a device.
To block by IP on MikroTik, use the command:
/ip firewall filter add chain=forward src-address=192.168.1.100 action=dropMost home routers don't have this feature; it's easier to block by MAC.
How to remove a device from Wi-Fi on Android or iOS?
On a smartphone you can only forget the network, but this won't remove it from the router. To completely remove the device from Wi-Fi:
- On Android:
Settings → Wi-Fi → Tap on the network → Forget. - On iOS:
Settings → Wi-Fi → Tap the "i" next to the network → Forget this network.
However, this will only delete the network data from your phone. To erase the device from the router's memory, follow the instructions in this article.
