The higher the number of devices connected to a WiFi network, the overall internet speed starts to drop. It may be an open WiFi network or a password-protected personal network, but too many users can cause slow browsing and inconsistent connectivity. While users struggle slow speeds, the WiFi owner (host) remains has full control over who can stay connected.
When you notice that unknown devices are using your bandwidth, you can block unwanted WiFi users without much effort using the Access Control feature available of most routers. Here is a step-by-step guide for TP-Link, D-Link and NetGear routers to help you secure your network.
Block WiFi users using Access Control
Access Control lets you select which devices can stay connected and which ones should be blocklisted. To enable it, follow these steps.
TP-Link: How to block WiFi users
- Open your web browser.
- Type 192.168.0.1 or 192.168.1.1.
- Log in using the default username and password (admin/admin).
- Navigate to Advanced > Security > Access Control.
- Under Online Devices, you will see all connected users.
- Click the Block Icon next to the device you want to remove.
- Click Save to apply changes.
D-Link: Block devices from your WiFi
- Open your web browser.
- Type 192.168.0.1 or 192.168.1.1.
- Log in with default credentials (admin/admin).
- Go to Wireless > Advanced Wireless > ACL Setup.
- Enable Wireless Access Control Mode.
- Select the MAC addresses of devices you want to allow or restrict.
- Click Apply to save changes.

NetGear: Restrict WiFi access easily
- Connect your device to the router’s WiFi.
- In your browser, open
- routerlogin.net or routerlogin.com
- Enter the username and password (admin/password).
- Go to Advanced > Advanced Setup > Wireless Settings.
- Select Set Up Access List.
- Click Add, select the device name from the list, and click Apply.
- Turn Access Control ON and save changes.
Once done, your WiFi will only allow devices whose MAC addresses you have approved, and others will not be permitted to access the WiFi.
Frequently Asked Questions
How can I block someone from using my WiFi?
Log in to your router’s admin panel, open the Access Control or MAC Filtering settings, select the device you want to block, and save the changes. The blocked device will no longer be able to connect to your WiFi network.
Can I block WiFi users without changing my password?
Yes. Most modern routers let you block individual devices using their MAC address or the Access Control feature, so you do not have to change your WiFi password.
How do I see who is connected to my WiFi?
Log in to your router’s settings and open the Connected Devices, Device List, or Online Devices section. You will see all devices currently connected to your network.
Can a blocked device reconnect to my WiFi?
Not while Access Control or MAC filtering remains enabled. If you remove the device from the block list or disable the feature, it can connect again.
Will blocking a device improve my internet speed?
Blocking unauthorized or unnecessary devices can free up bandwidth and may improve internet speed, especially if multiple users were sharing your connection.
