How to Disconnect a Device from Wi-Fi via a TP-Link Router: A Step-by-Step Guide

Have you noticed an unknown device connecting to your Wi-Fi network? Or do you want to limit your child's internet access at night? Disabling devices via the router TP-Link — is a simple way to control connections without changing the password. In this article, we'll cover all the current methods: from temporary blocking to complete banning by MAC address.

The procedure varies depending on the router model (for example, Archer C6, TL-WR841N or Deco) and firmware versions. We'll cover universal steps that work on 90% of the brand's devices, as well as highlight key differences between the new and old interfaces. If your router supports the app, Tether, you will find instructions for it too.

Important: Disabling a device via the router is not the same as changing the Wi-Fi password. In the first case, the blocking only affects that specific device, while other users continue to use the network. In the second case, all devices will be disabled until you enter a new password.

1. Preparation: How to access TP-Link router settings

Before disconnecting devices, you need to access the router's web interface. To do this:

• 🌐 Open a browser (Chrome, Firefox, Edge) on a computer or smartphone connected to the same Wi-Fi network.
• 🔗 Enter in the address bar 192.168.0.1 or 192.168.1.1 (less often - tplinkwifi.net). If the page does not open, check the router's IP address in the command line (ipconfig for Windows or ifconfig for macOS/Linux).
• 🔐 Enter your login and password. By default, this is admin/admin or admin/empty fieldIf you changed the data, use your own.

If you can't log in:

• 🔄 Reboot your router (button Power on the back panel) and try again after 1-2 minutes.
• 📡 Check that you are connected to the correct network (the Wi-Fi name should match the name on the router sticker).
• 🔧 Reset to factory settings by holding down the button Reset for 10 seconds (you will need to configure the network again!).

⚠️ Attention: After resetting, all connected devices will be disconnected, and Wi-Fi settings (network name, password) will be reset to factory defaults. This is a last resort—use it only if you've forgotten your control panel login information.

2. Method 1: Temporarily disable the device via "Wireless Mode"

The fastest method is to disable the device directly from the list of connected clients. This method is suitable if you need to block the device urgently, but not permanently (for example, while sleeping or during school).

Instructions:

1. In the router control panel, go to the section Wireless Mode → Wireless Mode Statistics (or Wireless → Wireless Statistics (in the English version).
2. In the table you will see all connected devices with the indication MAC addresses, IP addresses And host name (if defined). Find the one you need by name or MAC.
3. Click the button Disable (or Kick) near the device. In some models (for example, Archer C50) you may need to check the checkbox first.

The device will be immediately disconnected from the network, but can be reconnected if it knows the password. To make the block permanent, use the following method.

Make sure you are disabling the correct device (compare the MAC address)

Write down the MAC address in case you need to unlock it later.

Check if your device is using a static IP (this may interfere with blocking)

-->

3. Method 2: Permanent blocking by MAC address

If you want to permanently block a device from connecting to your network, add it MAC address blacklisted. This method works even after rebooting the router.

Step-by-step instructions:

1. Go to Wireless Mode → MAC Filtering (or Wireless → Wireless MAC Filtering).
2. Activate filtering by checking the box Turn on (Enable).
3. Select mode Deny the stations specified in the list access to the network (Deny).
4. In the MAC address field, enter the device address (for example, 00:1A:2B:3C:4D:5E). To find your MAC, look in Wireless statistics or on the device sticker.
5. Save the settings with the button Save (Save).

Now the device won't be able to connect to Wi-Fi, even if you enter the correct password. To unblock it, simply remove the MAC address from the list.

⚠️ Attention: Some devices (such as Android smartphones) may accidentally change their MAC address when connecting to new networks (a feature MAC Randomization). In this case, blocking may not work. To disable randomization, go to your phone's Wi-Fi settings and deactivate the "Random MAC" or "Private Address" option.

4. Method 3: Disconnect via the Tether or Deco app

If you have a router that supports a mobile app (for example, Archer or Deco), you can manage connections directly from your smartphone. This is convenient when you don't have access to a computer.

For Tether (routers Archer, TL-WR):

1. Open the app and connect to your router.
2. Go to the section Devices or Clients.
3. Find the desired device in the list and tap on it.
4. Select an option Disable or Block.

For Deco (Mesh systems):

1. In the appendix Deco go to Security → Devices.
2. Select the device and click Block.
3. To permanently block, add it to Blacklist.

The advantage of this method is notifications about new connections. For example, Deco can notify you if an unknown device connects to the network.

5. Additional settings: time and speed limits

Sometimes, instead of completely shutting down, it's more convenient to limit internet access on a schedule or reduce speed. This is useful for managing children's time online or for limiting bandwidth-hungry devices (such as torrent clients).

Time Limit (Parental Control):

1. Go to Advanced Settings → Access Control (Advanced → Parental Controls).
2. Add a new rule by specifying the MAC address of the device.
3. Set a schedule (for example, blocking from 11:00 PM to 7:00 AM).
4. Save the settings.

Rate limiting (QoS):

1. In the section Additional settings → QoS turn on the function.
2. Select mode IP/MAC restriction.
3. Specify the device and set the speed limit (for example, 1 Mbps).

These methods don't completely disable the device, but they make it less comfortable to use. For example, if the speed is limited to 1 Mbps, 4K video will stutter and online games will become unplayable.

What to do if the device ignores the lock?

If the device continues to connect despite MAC filtering, check:

1. Changing the MAC address on the device (for example, via Wi-Fi settings on Android or special programs on a PC).

2. Connecting via a guest network (if it is enabled on the router).

3. Using the second range (2.4 GHz vs 5 GHz) - blocking must be configured separately for each.

4. Resetting the router settings (if filtering rulesSuddenly stopped working).

6. Problems and solutions: why can't I turn off the device?

Sometimes users encounter difficulties locking their devices. Let's look at common situations and how to resolve them.

Problem 1: The "Disable" button is inactive or missing.

• 🔄 Make sure you have administrator rights (not guest access).
• 📋 Update your router firmware: older versions may not support this feature.
• 🖥️ Try a different browser (for example, Firefox instead of Chrome) - sometimes the interface displays incorrectly.

Problem 2: The device connects again after being blocked by MAC.

• 🔍 Make sure the MAC address is entered correctly (no spaces, case not important).
• 📡 Check if the device is connected to guest network (it has separate settings).
• 🔄 Reboot your router after applying the filter.

Problem 3: The device list displays incorrect names (for example, "Unknown").

• 📱 On your device (smartphone, laptop), check the hostname settings (in Windows: Control Panel → System → Advanced Settings → Computer Name).
• 🔧 Enable the option in your router Enable customer list (if any).
• 🔄 Reconnect the device - sometimes the name is only detected after reconnecting.

⚠️ Attention: On some firmware versions TP-Link (especially on older models like TL-WR740N) the device disconnection feature may be missing. In this case, the only options are to change the Wi-Fi password or use MAC filtering.

7. Alternative Methods: When Standard Methods Don't Work

If you are unable to disable the device via the web interface, try these options:

1. Change your Wi-Fi password

The most radical, yet reliable, solution is to change your network password. All devices will be disconnected, and only those you share the new password with will be able to connect.

1. Go to Wireless → Wireless Security.
2. In the field Wi-Fi password Enter a new key (we recommend using at least 12 characters with numbers and letters).
3. Save the settings.

2. Disabling DHCP for a specific device

If a blocked device uses a static IP, it can bypass MAC filtering. To prevent this:

1. Find the IP address of the device in Wireless statistics.
2. Go to Local Area Network → DHCP.
3. In the section Address reservation add a rule by binding the device's MAC address to a non-existent IP (e.g. 192.168.0.254).
4. Save and reboot the router.

3. Using a guest network

Create a separate guest network with a different password and connect only trusted devices to it. Unwanted devices will remain on the main network, which can be disabled or restricted.

FAQ: Frequently asked questions about disconnecting devices from Wi-Fi

Is it possible to turn off the device without going into the router settings?

Yes, if you have a router that supports the app. Tether or Deco. Also some models (for example, Archer AX6000) support voice control via Alice or Google Assistant (command “Disconnect device [name] from Wi-Fi”).

Without access to the router, the only way is to physically disconnect it from the power supply, but this will break the connection for all devices.

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

Check the list of devices in Wireless statisticsUnknown gadgets usually have:

• Unclear names (eg. android-1a2b3c).
• MAC addresses that do not match your devices (check through stickers or gadget settings).
• High traffic (if the router supports monitoring).

For detailed analysis, use programs like Wireless Network Watcher (Windows) or Fing (mobile).

Will the device consume traffic if it is disabled via the router?

No. After switching off (via the button) Kick (or MAC filter) the device completely loses access to the network and cannot consume traffic. However:

• If the device is connected to the router via cable (Ethernet), Wi-Fi blocking does not apply to it.
• Some smart devices (such as cameras) may try to reconnect, increasing the load on the router.

Is it possible to turn off the device on a schedule (for example, at night)?

Yes, use the function for this Parental Control (Access Control):

1. Please enter the MAC address of the device.
2. Set a time frame (e.g. 10:00 PM to 8:00 AM).
3. Save the rule.

During this time, the device will be unable to connect to Wi-Fi, even if it knows the password. This feature is available on most modern routers. TP-Link (except for budget models like TL-WR840N).

What should I do if my router starts to slow down after being blocked?

This can happen for two reasons:

1. Too many filtering rules (more than 20-30 MAC addresses). Solution: Delete unnecessary entries or update the firmware.
2. Conflict with other functions (For example, QoS or IPTV). Solution: disable additional services in the section Additional settings.

If the problem persists, reset the router to factory settings and set up blocking again.
