How to See and Block Wi-Fi Users on a TP-Link Router

If your internet feels slow and you think someone else is using your Wi-Fi, you can check every connected device and block the ones you do not recognize, straight from your TP-Link router's settings page. You do not need an app.

In this guide I show how to log in, how to tell your own devices from strangers, how to block a device properly and how to stop the same person from getting back in.

Two terms you will see: IP and MAC address

Every device on your network shows an IP address, such as 192.168.0.105. The router hands this out and it can change. Each device also has a MAC address, such as 3C:22:FB:1A:4D:90. Think of it as a device's ID card. The router uses the MAC address to recognize and block a device, so that is the number that matters here.

Step 1: Log in to your router

Connect to your Wi-Fi, or plug a computer into the router with a cable, and open a browser.
Go to 192.168.0.1 or tplinkwifi.net. Some models use 192.168.1.1. The correct address is printed on the label under the router.
Enter your router password. Older models use admin and admin by default. Newer ones ask you to create a password on first login.

If you still use the default admin password, change it while you are here. Anyone on your Wi-Fi could otherwise log in to the router and change your settings.

Step 2: See who is connected

The home screen shows your wireless and wired clients. Click them to see each device's name, IP and MAC address.

To tell which devices are yours, find the MAC address on your own phone, laptop and TV and compare. On a phone, it is usually under Settings, About phone or the Wi-Fi network details. A quick trick: switch off Wi-Fi on one of your devices and watch which entry disappears from the list.

Modern iPhones and Android phones often use a private Wi-Fi address, which is a different MAC for each network. If you cannot match your phone, check the Wi-Fi details screen for your home network, which shows the address it uses there.

Step 3: Block a device

Click Advanced at the top.
Go to Security, then Access Control.
Turn Access Control on. This is the step people miss: if it is off, the block list does nothing.
Choose Blacklist mode. Newer firmware may call it Blocklist.
Select the device from the online devices list, click Block, then Save.

The blocked device drops off your Wi-Fi straight away. To unblock it, remove it from the list and save.

Step 4: Change your Wi-Fi password

Blocking one device does not stop the same person from joining with another phone if they know your password. After blocking, change it:

Go to Advanced, then Wireless, then Wireless Settings.
Make sure the security is set to WPA2-PSK or WPA3 if your devices support it.
Enter a new, long password and save.

Every device will disconnect, including yours. Reconnect your own devices with the new password.

Good to know

You can only block wireless devices this way, not devices plugged in with a cable.
Whitelist mode, or Allowlist, does the opposite: only devices on the list can connect. Add all your own devices first, or you will lock yourself out.
Turn off WPS in the wireless settings if you do not use it. It is a button-based way to join that some people abuse.
Use the Guest Network feature for visitors. They get internet access without seeing your other devices, and you can change that password whenever you like.
Check for firmware updates under Advanced, then System Tools. Updates fix security problems.

The short version

Log in to your router, compare the connected devices with your own, turn on Access Control, block the strangers and change your Wi-Fi password. Then use a guest network for visitors so your main password stays private.
